1 2 Advanced Linux Sound Architecture - Driver 3 ========================================== 4 Configuration guide 5 6 7 Kernel Configuration 8 ==================== 9 10 To enable ALSA support you need at least to build the kernel with 11 primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS, 12 you don't have to choose any of the OSS modules. 13 14 Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and 15 PCM supports if you want to run OSS applications with ALSA. 16 17 If you want to support the WaveTable functionality on cards such as 18 SB Live! then you need to enable "Sequencer support" 19 (CONFIG_SND_SEQUENCER). 20 21 To make ALSA debug messages more verbose, enable the "Verbose printk" 22 and "Debug" options. To check for memory leaks, turn on "Debug memory" 23 too. "Debug detection" will add checks for the detection of cards. 24 25 Please note that all the ALSA ISA drivers support the Linux isapnp API 26 (if the card supports ISA PnP). You don't need to configure the cards 27 using isapnptools. 28 29 30 Creating ALSA devices 31 ===================== 32 33 This depends on your distribution, but normally you use the /dev/MAKEDEV 34 script to create the necessary device nodes. On some systems you use a 35 script named 'snddevices'. 36 37 38 Module parameters 39 ================= 40 41 The user can load modules with options. If the module supports more than 42 one card and you have more than one card of the same type then you can 43 specify multiple values for the option separated by commas. 44 45 Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed. 46 47 Module snd 48 ---------- 49 50 The core ALSA module. It is used by all ALSA card drivers. 51 It takes the following options which have global effects. 52 53 major - major number for sound driver 54 - Default: 116 55 cards_limit 56 - limiting card index for auto-loading (1-8) 57 - Default: 1 58 - For auto-loading more than one card, specify this 59 option together with snd-card-X aliases. 60 slots - Reserve the slot index for the given driver. 61 This option takes multiple strings. 62 See "Module Autoloading Support" section for details. 63 debug - Specifies the debug message level 64 (0 = disable debug prints, 1 = normal debug messages, 65 2 = verbose debug messages) 66 This option appears only when CONFIG_SND_DEBUG=y. 67 This option can be dynamically changed via sysfs 68 /sys/modules/snd/parameters/debug file. 69 70 Module snd-pcm-oss 71 ------------------ 72 73 The PCM OSS emulation module. 74 This module takes options which change the mapping of devices. 75 76 dsp_map - PCM device number maps assigned to the 1st OSS device. 77 - Default: 0 78 adsp_map - PCM device number maps assigned to the 2st OSS device. 79 - Default: 1 80 nonblock_open 81 - Don't block opening busy PCM devices. Default: 1 82 83 For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of 84 the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped 85 to PCM #0 of the card #0. 86 For changing the second or later card, specify the option with 87 commas, such like "dsp_map=0,1". 88 89 nonblock_open option is used to change the behavior of the PCM 90 regarding opening the device. When this option is non-zero, 91 opening a busy OSS PCM device won't be blocked but return 92 immediately with EAGAIN (just like O_NONBLOCK flag). 93 94 Module snd-rawmidi 95 ------------------ 96 97 This module takes options which change the mapping of devices. 98 similar to those of the snd-pcm-oss module. 99 100 midi_map - MIDI device number maps assigned to the 1st OSS device. 101 - Default: 0 102 amidi_map - MIDI device number maps assigned to the 2st OSS device. 103 - Default: 1 104 105 Common parameters for top sound card modules 106 -------------------------------------------- 107 108 Each of top level sound card module takes the following options. 109 110 index - index (slot #) of sound card 111 - Values: 0 through 31 or negative 112 - If nonnegative, assign that index number 113 - if negative, interpret as a bitmask of permissible 114 indices; the first free permitted index is assigned 115 - Default: -1 116 id - card ID (identifier or name) 117 - Can be up to 15 characters long 118 - Default: the card type 119 - A directory by this name is created under /proc/asound/ 120 containing information about the card 121 - This ID can be used instead of the index number in 122 identifying the card 123 enable - enable card 124 - Default: enabled, for PCI and ISA PnP cards 125 126 Module snd-adlib 127 ---------------- 128 129 Module for AdLib FM cards. 130 131 port - port # for OPL chip 132 133 This module supports multiple cards. It does not support autoprobe, so 134 the port must be specified. For actual AdLib FM cards it will be 0x388. 135 Note that this card does not have PCM support and no mixer; only FM 136 synthesis. 137 138 Make sure you have "sbiload" from the alsa-tools package available and, 139 after loading the module, find out the assigned ALSA sequencer port 140 number through "sbiload -l". Example output: 141 142 Port Client name Port name 143 64:0 OPL2 FM synth OPL2 FM Port 144 145 Load the std.sb and drums.sb patches also supplied by sbiload: 146 147 sbiload -p 64:0 std.sb drums.sb 148 149 If you use this driver to drive an OPL3, you can use std.o3 and drums.o3 150 instead. To have the card produce sound, use aplaymidi from alsa-utils: 151 152 aplaymidi -p 64:0 foo.mid 153 154 Module snd-ad1816a 155 ------------------ 156 157 Module for sound cards based on Analog Devices AD1816A/AD1815 ISA chips. 158 159 clockfreq - Clock frequency for AD1816A chip (default = 0, 33000Hz) 160 161 This module supports multiple cards, autoprobe and PnP. 162 163 Module snd-ad1848 164 ----------------- 165 166 Module for sound cards based on AD1848/AD1847/CS4248 ISA chips. 167 168 port - port # for AD1848 chip 169 irq - IRQ # for AD1848 chip 170 dma1 - DMA # for AD1848 chip (0,1,3) 171 172 This module supports multiple cards.

force the model name 790 position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF) 791 probe_mask - Bitmask to probe codecs (default = -1, meaning all slots) 792 When the bit 8 (0x100) is set, the lower 8 bits are used 793 as the "fixed" codec slots; i.e. the driver probes the 794 slots regardless what hardware reports back 795 probe_only - Only probing and no codec initialization (default=off); 796 Useful to check the initial codec status for debugging 797 bdl_pos_adj - Specifies the DMA IRQ timing delay in samples. 798 Passing -1 will make the driver to choose the appropriate 799 value based on the controller chip. 800 patch - Specifies the early "patch" files to modify the HD-audio 801 setup before initializing the codecs. This option is 802 available only when CONFIG_SND_HDA_PATCH_LOADER=y is set. 803 See HD-Audio.txt for details. 804 beep_mode - Selects the beep registration mode (0=off, 1=on, 2= 805 dynamic registration via mute switch on/off); the default 806 value is set via CONFIG_SND_HDA_INPUT_BEEP_MODE kconfig. 807 808 [Single (global) options] 809 single_cmd - Use single immediate commands to communicate with 810 codecs (for debugging only) 811 enable_msi - Enable Message Signaled Interrupt (MSI) (default = off) 812 power_save - Automatic power-saving timeout (in second, 0 = 813 disable) 814 power_save_controller - Reset HD-audio controller in power-saving mode 815 (default = on) 816 817 This module supports multiple cards and autoprobe. 818 819 See Documentation/sound/alsa/HD-Audio.txt for more details about 820 HD-audio driver. 821 822 Each codec may have a model table for different configurations. 823 If your machine isn't listed there, the default (usually minimal) 824 configuration is set up. You can pass "model=<name>" option to 825 specify a certain model in such a case. There are different 826 models depending on the codec chip. The list of available models 827 is found in HD-Audio-Models.txt 828 829 The model name "genric" is treated as a special case. When this 830 model is given, the driver uses the generic codec parser without 831 "codec-patch". It's sometimes good for testing and debugging. 832 833 If the default configuration doesn't work and one of the above 834 matches with your device, report it together with alsa-info.sh 835 output (with --no-upload option) to kernel bugzilla or alsa-devel 836 ML (see the section "Links and Addresses"). 837 838 power_save and power_save_controller options are for power-saving 839 mode. See powersave.txt for details. 840 841 Note 2: If you get click noises on output, try the module option 842 position_fix=1 or 2. position_fix=1 will use the SD_LPIB 843 register value without FIFO size correction as the current 844 DMA pointer. position_fix=2 will make the driver to use 845 the position buffer instead of reading SD_LPIB register. 846 (Usually SD_LPIB register is more accurate than the 847 position buffer.) 848 849 NB: If you get many "azx_get_response timeout" messages at 850 loading, it's likely a problem of interrupts (e.g. ACPI irq 851 routing). Try to boot with options like "pci=noacpi". Also, you 852 can try "single_cmd=1" module option. This will switch the 853 communication method between HDA controller and codecs to the 854 single immediate commands instead of CORB/RIRB. Basically, the 855 single command mode is provided only for BIOS, and you won't get 856 unsolicited events, too. But, at least, this works independently 857 from the irq. Remember this is a last resort, and should be 858 avoided as much as possible... 859 860 MORE NOTES ON "azx_get_response timeout" PROBLEMS: 861 On some hardwares, you may need to add a proper probe_mask option 862 to avoid the "azx_get_response timeout" problem above, instead. 863 This occurs when the access to non-existing or non-working codec slot 864 (likely a modem one) causes a stall of the communication via HD-audio 865 bus. You can see which codec slots are probed by enabling 866 CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec 867 proc files. Then limit the slots to probe by probe_mask option. 868 For example, probe_mask=1 means to probe only the first slot, and 869 probe_mask=4 means only the third slot. 870 871 The power-management is supported. 872 873 Module snd-hdsp 874 --------------- 875 876 Module for RME Hammerfall DSP audio interface(s) 877 878 This module supports multiple cards. 879 880 Note: The firmware data can be automatically loaded via hotplug 881 when CONFIG_FW_LOADER is set. Otherwise, you need to load 882 the firmware via hdsploader utility included in alsa-tools 883 package. 884 The firmware data is found in alsa-firmware package. 885 886 Note: snd-page-alloc module does the job which snd-hammerfall-mem 887 module did formerly. It will allocate the buffers in advance 888 when any HDSP cards are found. To make the buffer 889 allocation sure, load snd-page-alloc module in the early 890 stage of boot sequence.

Note that it has been discontinued, but the 1281 Voyetra Turtle Beach knowledge base entry for it is still available 1282 at 1283 http://www.turtlebeach.com/site/kb_ftp/790.asp 1284 1285 Module snd-msnd-pinnacle 1286 ------------------------ 1287 1288 Module for Turtle Beach MultiSound Pinnacle/Fiji soundcards. 1289 1290 io - Port # for pinnacle/fiji card 1291 irq - IRQ # for pinnalce/fiji card 1292 mem - Memory address (0xb0000, 0xc8000, 0xd0000, 0xd8000, 1293 0xe0000 or 0xe8000) 1294 write_ndelay - enable write ndelay (default = 1) 1295 calibrate_signal - calibrate signal (default = 0) 1296 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1297 1298 The driver requires firmware files "turtlebeach/pndspini.bin" and 1299 "turtlebeach/pndsperm.bin" in the proper firmware directory. 1300 1301 Module snd-mtpav 1302 ---------------- 1303 1304 Module for MOTU MidiTimePiece AV multiport MIDI (on the parallel 1305 port). 1306 1307 port - I/O port # for MTPAV (0x378,0x278, default=0x378) 1308 irq - IRQ # for MTPAV (7,5, default=7) 1309 hwports - number of supported hardware ports, default=8. 1310 1311 Module supports only 1 card. This module has no enable option. 1312 1313 Module snd-mts64 1314 ---------------- 1315 1316 Module for Ego Systems (ESI) Miditerminal 4140 1317 1318 This module supports multiple devices. 1319 Requires parport (CONFIG_PARPORT). 1320 1321 Module snd-nm256 1322 ---------------- 1323 1324 Module for NeoMagic NM256AV/ZX chips 1325 1326 playback_bufsize - max playback frame size in kB (4-128kB) 1327 capture_bufsize - max capture frame size in kB (4-128kB) 1328 force_ac97 - 0 or 1 (disabled by default) 1329 buffer_top - specify buffer top address 1330 use_cache - 0 or 1 (disabled by default) 1331 vaio_hack - alias buffer_top=0x25a800 1332 reset_workaround - enable AC97 RESET workaround for some laptops 1333 reset_workaround2 - enable extended AC97 RESET workaround for some 1334 other laptops 1335 1336 This module supports one chip and autoprobe. 1337 1338 The power-management is supported. 1339 1340 Note: on some notebooks the buffer address cannot be detected 1341 automatically, or causes hang-up during initialization. 1342 In such a case, specify the buffer top address explicitly via 1343 the buffer_top option. 1344 For example, 1345 Sony F250: buffer_top=0x25a800 1346 Sony F270: buffer_top=0x272800 1347 The driver supports only ac97 codec. It's possible to force 1348 to initialize/use ac97 although it's not detected. In such a 1349 case, use force_ac97=1 option - but *NO* guarantee whether it 1350 works! 1351 1352 Note: The NM256 chip can be linked internally with non-AC97 1353 codecs. This driver supports only the AC97 codec, and won't work 1354 with machines with other (most likely CS423x or OPL3SAx) chips, 1355 even though the device is detected in lspci. In such a case, try 1356 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP 1357 but some doesn't have ISA PnP. You'll need to specify isapnp=0 1358 and proper hardware parameters in the case without ISA PnP. 1359 1360 Note: some laptops need a workaround for AC97 RESET. For the 1361 known hardware like Dell Latitude LS and Sony PCG-F305, this 1362 workaround is enabled automatically. For other laptops with a 1363 hard freeze, you can try reset_workaround=1 option. 1364 1365 Note: Dell Latitude CSx laptops have another problem regarding 1366 AC97 RESET. On these laptops, reset_workaround2 option is 1367 turned on as default. This option is worth to try if the 1368 previous reset_workaround option doesn't help. 1369 1370 Note: This driver is really crappy. It's a porting from the 1371 OSS driver, which is a result of black-magic reverse engineering. 1372 The detection of codec will fail if the driver is loaded *after* 1373 X-server as described above. You might be able to force to load 1374 the module, but it may result in hang-up. Hence, make sure that 1375 you load this module *before* X if you encounter this kind of 1376 problem. 1377 1378 Module snd-opl3sa2 1379 ------------------ 1380 1381 Module for Yamaha OPL3-SA2/SA3 sound cards. 1382 1383 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1384 1385 with isapnp=0, the following options are available: 1386 1387 port - control port # for OPL3-SA chip (0x370) 1388 sb_port - SB port # for OPL3-SA chip (0x220,0x240) 1389 wss_port - WSS port # for OPL3-SA chip (0x530,0xe80,0xf40,0x604) 1390 midi_port - port # for MPU-401 UART (0x300,0x330), -1 = disable 1391 fm_port - FM port # for OPL3-SA chip (0x388), -1 = disable 1392 irq - IRQ # for OPL3-SA chip (5,7,9,10) 1393 dma1 - first DMA # for Yamaha OPL3-SA chip (0,1,3) 1394 dma2 - second DMA # for Yamaha OPL3-SA chip (0,1,3), -1 = disable 1395 1396 This module supports multiple cards and ISA PnP. It does not support 1397 autoprobe (if ISA PnP is not used) thus all ports must be specified!!! 1398 1399 The power-management is supported. 1400 1401 Module snd-opti92x-ad1848 1402 ------------------------- 1403 1404 Module for sound cards based on OPTi 82c92x and Analog Devices AD1848 chips. 1405 Module works with OAK Mozart cards as well. 1406 1407 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1408 1409 with isapnp=0, the following options are available: 1410 1411 port - port # for WSS chip (0x530,0xe80,0xf40,0x604) 1412 mpu_port - port # for MPU-401 UART (0x300,0x310,0x320,0x330) 1413 fm_port - port # for OPL3 device (0x388) 1414 irq - IRQ # for WSS chip (5,7,9,10,11) 1415 mpu_irq - IRQ # for MPU-401 UART (5,7,9,10) 1416 dma1 - first DMA # for WSS chip (0,1,3) 1417 1418 This module supports only one card, autoprobe and PnP. 1419 1420 Module snd-opti92x-cs4231 1421 ------------------------- 1422 1423 Module for sound cards based on OPTi 82c92x and Crystal CS4231 chips. 1424 1425 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1426 1427 with isapnp=0, the following options are available: 1428 1429 port - port # for WSS chip (0x530,0xe80,0xf40,0x604) 1430 mpu_port - port # for MPU-401 UART (0x300,0x310,0x320,0x330) 1431 fm_port - port # for OPL3 device (0x388) 1432 irq - IRQ # for WSS chip (5,7,9,10,11) 1433 mpu_irq - IRQ # for MPU-401 UART (5,7,9,10) 1434 dma1 - first DMA # for WSS chip (0,1,3) 1435 dma2 - second DMA # for WSS chip (0,1,3) 1436 1437 This module supports only one card, autoprobe and PnP. 1438 1439 Module snd-opti93x 1440 ------------------ 1441 1442 Module for sound cards based on OPTi 82c93x chips. 1443 1444 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1445 1446 with isapnp=0, the following options are available: 1447 1448 port - port # for WSS chip (0x530,0xe80,0xf40,0x604) 1449 mpu_port - port # for MPU-401 UART (0x300,0x310,0x320,0x330) 1450 fm_port - port # for OPL3 device (0x388) 1451 irq - IRQ # for WSS chip (5,7,9,10,11) 1452 mpu_irq - IRQ # for MPU-401 UART (5,7,9,10) 1453 dma1 - first DMA # for WSS chip (0,1,3) 1454 dma2 - second DMA # for WSS chip (0,1,3) 1455 1456 This module supports only one card, autoprobe and PnP. 1457 1458 Module snd-oxygen 1459 ----------------- 1460 1461 Module for sound cards based on the C-Media CMI8788 chip: 1462 * Asound A-8788 1463 * AuzenTech X-Meridian 1464 * Bgears b-Enspirer 1465 * Club3D Theatron DTS 1466 * HT-Omega Claro (plus) 1467 * HT-Omega Claro halo (XT) 1468 * Razer Barracuda AC-1 1469 * Sondigo Inferno 1470 1471 This module supports autoprobe and multiple cards. 1472 1473 Module snd-pcsp 1474 ----------------- 1475 1476 Module for internal PC-Speaker. 1477 1478 nopcm - Disable PC-Speaker PCM sound.

Assume that we need to boot the OS (default:no) 1714 If yes, then during driver loading, the state of the board is 1715 ignored, and we reset the board and load the firmware anyway. 1716 fx_raw - Assume that the FX process needs help (default:yes) 1717 If false, we'll leave the FX processor in whatever state it is 1718 when the driver is loaded. The default is to download the 1719 microprogram and associated coefficients to set it up for 1720 "default" operation, whatever that means. 1721 debug_default - Debug parameters for card initialization 1722 wait_usecs - How long to wait without sleeping, usecs 1723 (default:150) 1724 This magic number seems to give pretty optimal throughput 1725 based on my limited experimentation. 1726 If you want to play around with it and find a better value, be 1727 my guest. Remember, the idea is to get a number that causes us 1728 to just busy wait for as many WaveFront commands as possible, 1729 without coming up with a number so large that we hog the whole 1730 CPU. 1731 Specifically, with this number, out of about 134,000 status 1732 waits, only about 250 result in a sleep. 1733 sleep_interval - How long to sleep when waiting for reply 1734 (default: 100) 1735 sleep_tries - How many times to try sleeping during a wait 1736 (default: 50) 1737 ospath - Pathname to processed ICS2115 OS firmware 1738 (default:wavefront.os) 1739 The path name of the ISC2115 OS firmware. In the recent 1740 version, it's handled via firmware loader framework, so it 1741 must be installed in the proper path, typically, 1742 /lib/firmware. 1743 reset_time - How long to wait for a reset to take effect 1744 (default:2) 1745 ramcheck_time - How many seconds to wait for the RAM test 1746 (default:20) 1747 osrun_time - How many seconds to wait for the ICS2115 OS 1748 (default:10) 1749 1750 This module supports multiple cards and ISA PnP. 1751 1752 Note: the firmware file "wavefront.os" was located in the earlier 1753 version in /etc. Now it's loaded via firmware loader, and 1754 must be in the proper firmware path, such as /lib/firmware. 1755 Copy (or symlink) the file appropriately if you get an error 1756 regarding firmware downloading after upgrading the kernel. 1757 1758 Module snd-sonicvibes 1759 --------------------- 1760 1761 Module for S3 SonicVibes PCI sound cards. 1762 * PINE Schubert 32 PCI 1763 1764 reverb - Reverb Enable - 1 = enable, 0 = disable (default) 1765 - SoundCard must have onboard SRAM for this. 1766 mge - Mic Gain Enable - 1 = enable, 0 = disable (default) 1767 1768 This module supports multiple cards and autoprobe. 1769 1770 Module snd-serial-u16550 1771 ------------------------ 1772 1773 Module for UART16550A serial MIDI ports. 1774 1775 port - port # for UART16550A chip 1776 irq - IRQ # for UART16550A chip, -1 = poll mode 1777 speed - speed in bauds (9600,19200,38400,57600,115200) 1778 38400 = default 1779 base - base for divisor in bauds (57600,115200,230400,460800) 1780 115200 = default 1781 outs - number of MIDI ports in a serial port (1-4) 1782 1 = default 1783 adaptor - Type of adaptor. 1784 0 = Soundcanvas, 1 = MS-124T, 2 = MS-124W S/A, 1785 3 = MS-124W M/B, 4 = Generic 1786 1787 This module supports multiple cards. This module does not support autoprobe 1788 thus the main port must be specified!!! Other options are optional. 1789 1790 Module snd-trident 1791 ------------------ 1792 1793 Module for Trident 4DWave DX/NX sound cards. 1794 * Best Union Miss Melody 4DWave PCI 1795 * HIS 4DWave PCI 1796 * Warpspeed ONSpeed 4DWave PCI 1797 * AzTech PCI 64-Q3D 1798 * Addonics SV 750 1799 * CHIC True Sound 4Dwave 1800 * Shark Predator4D-PCI 1801 * Jaton SonicWave 4D 1802 * SiS SI7018 PCI Audio 1803 * Hoontech SoundTrack Digital 4DWave NX 1804 1805 pcm_channels - max channels (voices) reserved for PCM 1806 wavetable_size - max wavetable size in kB (4-?kb) 1807 1808 This module supports multiple cards and autoprobe. 1809 1810 The power-management is supported. 1811 1812 Module snd-ua101 1813 ---------------- 1814 1815 Module for the Edirol UA-101/UA-1000 audio/MIDI interfaces. 1816 1817 This module supports multiple devices, autoprobe and hotplugging. 1818 1819 Module snd-usb-audio 1820 -------------------- 1821 1822 Module for USB audio and USB MIDI devices. 1823 1824 vid - Vendor ID for the device (optional) 1825 pid - Product ID for the device (optional) 1826 nrpacks - Max. number of packets per URB (default: 8) 1827 async_unlink - Use async unlink mode (default: yes) 1828 device_setup - Device specific magic number (optional) 1829 - Influence depends on the device 1830 - Default: 0x0000 1831 ignore_ctl_error - Ignore any USB-controller regarding mixer 1832 interface (default: no) 1833 1834 This module supports multiple devices, autoprobe and hotplugging. 1835 1836 NB: nrpacks parameter can be modified dynamically via sysfs. 1837 Don't put the value over 20. Changing via sysfs has no sanity 1838 check. 1839 NB: async_unlink=0 would cause Oops. It remains just for 1840 debugging purpose (if any). 1841 NB: ignore_ctl_error=1 may help when you get an error at accessing 1842 the mixer element such as URB error -22. This happens on some 1843 buggy USB device or the controller. 1844 1845 Module snd-usb-caiaq 1846 -------------------- 1847 1848 Module for caiaq UB audio interfaces, 1849 * Native Instruments RigKontrol2 1850 * Native Instruments Kore Controller 1851 * Native Instruments Audio Kontrol 1 1852 * Native Instruments Audio 8 DJ 1853 1854 This module supports multiple devices, autoprobe and hotplugging. 1855 1856 Module snd-usb-usx2y 1857 -------------------- 1858 1859 Module for Tascam USB US-122, US-224 and US-428 devices. 1860 1861 This module supports multiple devices, autoprobe and hotplugging. 1862 1863 Note: you need to load the firmware via usx2yloader utility included 1864 in alsa-tools and alsa-firmware packages. 1865 1866 Module snd-via82xx 1867 ------------------ 1868 1869 Module for AC'97 motherboards based on VIA 82C686A/686B, 8233, 1870 8233A, 8233C, 8235, 8237 (south) bridge. 1871 1872 mpu_port - 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup 1873 [VIA686A/686B only] 1874 joystick - Enable joystick (default off) [VIA686A/686B only] 1875 ac97_clock - AC'97 codec clock base (default 48000Hz) 1876 dxs_support - support DXS channels, 1877 0 = auto (default), 1 = enable, 2 = disable, 1878 3 = 48k only, 4 = no VRA, 5 = enable any sample 1879 rate and different sample rates on different 1880 channels 1881 [VIA8233/C, 8235, 8237 only] 1882 ac97_quirk - AC'97 workaround for strange hardware 1883 See "AC97 Quirk Option" section below. 1884 1885 This module supports one chip and autoprobe. 1886 1887 Note: on some SMP motherboards like MSI 694D the interrupts might 1888 not be generated properly. In such a case, please try to 1889 set the SMP (or MPS) version on BIOS to 1.1 instead of 1890 default value 1.4. Then the interrupt number will be 1891 assigned under 15. You might also upgrade your BIOS. 1892 1893 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) 1894 channels as the first PCM. On these channels, up to 4 1895 streams can be played at the same time, and the controller 1896 can perform sample rate conversion with separate rates for 1897 each channel. 1898 As default (dxs_support = 0), 48k fixed rate is chosen 1899 except for the known devices since the output is often 1900 noisy except for 48k on some mother boards due to the 1901 bug of BIOS. 1902 Please try once dxs_support=5 and if it works on other 1903 sample rates (e.g. 44.1kHz of mp3 playback), please let us 1904 know the PCI subsystem vendor/device id's (output of 1905 "lspci -nv"). 1906 If dxs_support=5 does not work, try dxs_support=4; if it 1907 doesn't work too, try dxs_support=1. (dxs_support=1 is 1908 usually for old motherboards. The correct implemented 1909 board should work with 4 or 5.) If it still doesn't 1910 work and the default setting is ok, dxs_support=3 is the 1911 right choice. If the default setting doesn't work at all, 1912 try dxs_support=2 to disable the DXS channels. 1913 In any cases, please let us know the result and the 1914 subsystem vendor/device ids. See "Links and Addresses" 1915 below. 1916 1917 Note: for the MPU401 on VIA823x, use snd-mpu401 driver 1918 additionally. The mpu_port option is for VIA686 chips only. 1919 1920 The power-management is supported. 1921 1922 Module snd-via82xx-modem 1923 ------------------------ 1924 1925 Module for VIA82xx AC97 modem 1926 1927 ac97_clock - AC'97 codec clock base (default 48000Hz) 1928 1929 This module supports one card and autoprobe. 1930 1931 Note: The default index value of this module is -2, i.e. the first 1932 slot is excluded. 1933 1934 The power-management is supported. 1935 1936 Module snd-virmidi 1937 ------------------ 1938 1939 Module for virtual rawmidi devices. 1940 This module creates virtual rawmidi devices which communicate 1941 to the corresponding ALSA sequencer ports. 1942 1943 midi_devs - MIDI devices # (1-4, default=4) 1944 1945 This module supports multiple cards. 1946 1947 Module snd-virtuoso 1948 ------------------- 1949 1950 Module for sound cards based on the Asus AV100/AV200 chips, 1951 i.e., Xonar D1, DX, D2, D2X, DS, HDAV1.3 (Deluxe), Essence ST 1952 (Deluxe) and Essence STX. 1953 1954 This module supports autoprobe and multiple cards. 1955 1956 Module snd-vx222 1957 ---------------- 1958 1959 Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards. 1960 1961 mic - Enable Microphone on V222 Mic (NYI) 1962 ibl - Capture IBL size. (default = 0, minimum size) 1963 1964 This module supports multiple cards. 1965 1966 When the driver is compiled as a module and the hotplug firmware 1967 is supported, the firmware data is loaded via hotplug automatically. 1968 Install the necessary firmware files in alsa-firmware package. 1969 When no hotplug fw loader is available, you need to load the 1970 firmware via vxloader utility in alsa-tools package. To invoke 1971 vxloader automatically, add the following to /etc/modprobe.conf 1972 1973 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader 1974 1975 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to 1976 /etc/modules.conf, instead.) 1977 IBL size defines the interrupts period for PCM. The smaller size 1978 gives smaller latency but leads to more CPU consumption, too. 1979 The size is usually aligned to 126. As default (=0), the smallest 1980 size is chosen. The possible IBL values can be found in 1981 /proc/asound/cardX/vx-status proc file. 1982 1983 The power-management is supported. 1984 1985 Module snd-vxpocket 1986 ------------------- 1987 1988 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards. 1989 1990 ibl - Capture IBL size. (default = 0, minimum size) 1991 1992 This module supports multiple cards. The module is compiled only when 1993 PCMCIA is supported on kernel. 1994 1995 With the older 2.6.x kernel, to activate the driver via the card 1996 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the 1997 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no 1998 longer require a config file. 1999 2000 When the driver is compiled as a module and the hotplug firmware 2001 is supported, the firmware data is loaded via hotplug automatically. 2002 Install the necessary firmware files in alsa-firmware package. 2003 When no hotplug fw loader is available, you need to load the 2004 firmware via vxloader utility in alsa-tools package. 2005 2006 About capture IBL, see the description of snd-vx222 module. 2007 2008 Note: snd-vxp440 driver is merged to snd-vxpocket driver since 2009 ALSA 1.0.10. 2010 2011 The power-management is supported. 2012 2013 Module snd-ymfpci 2014 ----------------- 2015 2016 Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x). 2017 2018 mpu_port - 0x300,0x330,0x332,0x334, 0 (disable) by default, 2019 1 (auto-detect for YMF744/754 only) 2020 fm_port - 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default 2021 1 (auto-detect for YMF744/754 only) 2022 joystick_port - 0x201,0x202,0x204,0x205, 0 (disable) by default, 2023 1 (auto-detect) 2024 rear_switch - enable shared rear/line-in switch (bool) 2025 2026 This module supports autoprobe and multiple chips. 2027 2028 The power-management is supported. 2029 2030 Module snd-pdaudiocf 2031 -------------------- 2032 2033 Module for Sound Core PDAudioCF sound card. 2034 2035 The power-management is supported. 2036 2037 2038 AC97 Quirk Option 2039 ================= 2040 2041 The ac97_quirk option is used to enable/override the workaround for 2042 specific devices on drivers for on-board AC'97 controllers like 2043 snd-intel8x0. Some hardware have swapped output pins between Master 2044 and Headphone, or Surround (thanks to confusion of AC'97 2045 specifications from version to version :-) 2046 2047 The driver provides the auto-detection of known problematic devices, 2048 but some might be unknown or wrongly detected. In such a case, pass 2049 the proper value with this option. 2050 2051 The following strings are accepted: 2052 - default Don't override the default setting 2053 - none Disable the quirk 2054 - hp_only Bind Master and Headphone controls as a single control 2055 - swap_hp Swap headphone and master controls 2056 - swap_surround Swap master and surround controls 2057 - ad_sharing For AD1985, turn on OMS bit and use headphone 2058 - alc_jack For ALC65x, turn on the jack sense mode 2059 - inv_eapd Inverted EAPD implementation 2060 - mute_led Bind EAPD bit for turning on/off mute LED 2061 2062 For backward compatibility, the corresponding integer value -1, 0, 2063 ... are accepted, too. 2064 2065 For example, if "Master" volume control has no effect on your device 2066 but only "Headphone" does, pass ac97_quirk=hp_only module option. 2067 2068 2069 Configuring Non-ISAPNP Cards 2070 ============================ 2071 2072 When the kernel is configured with ISA-PnP support, the modules 2073 supporting the isapnp cards will have module options "isapnp". 2074 If this option is set, *only* the ISA-PnP devices will be probed. 2075 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option 2076 together with the proper i/o and irq configuration. 2077 2078 When the kernel is configured without ISA-PnP support, isapnp option 2079 will be not built in. 2080 2081 2082 Module Autoloading Support 2083 ========================== 2084 2085 The ALSA drivers can be loaded automatically on demand by defining 2086 module aliases. The string 'snd-card-%1' is requested for ALSA native 2087 devices where %i is sound card number from zero to seven. 2088 2089 To auto-load an ALSA driver for OSS services, define the string 2090 'sound-slot-%i' where %i means the slot number for OSS, which 2091 corresponds to the card index of ALSA. Usually, define this 2092 as the same card module. 2093 2094 An example configuration for a single emu10k1 card is like below: 2095 ----- /etc/modprobe.conf 2096 alias snd-card-0 snd-emu10k1 2097 alias sound-slot-0 snd-emu10k1 2098 ----- /etc/modprobe.conf 2099 2100 The available number of auto-loaded sound cards depends on the module 2101 option "cards_limit" of snd module. As default it's set to 1. 2102 To enable the auto-loading of multiple cards, specify the number of 2103 sound cards in that option. 2104 2105 When multiple cards are available, it'd better to specify the index 2106 number for each card via module option, too, so that the order of 2107 cards is kept consistent. 2108 2109 An example configuration for two sound cards is like below: 2110 2111 ----- /etc/modprobe.conf 2112 # ALSA portion 2113 options snd cards_limit=2 2114 alias snd-card-0 snd-interwave 2115 alias snd-card-1 snd-ens1371 2116 options snd-interwave index=0 2117 options snd-ens1371 index=1 2118 # OSS/Free portion 2119 alias sound-slot-0 snd-interwave 2120 alias sound-slot-1 snd-ens1371 2121 ----- /etc/modprobe.conf 2122 2123 In this example, the interwave card is always loaded as the first card 2124 (index 0) and ens1371 as the second (index 1). 2125 2126 Alternative (and new) way to fixate the slot assignment is to use 2127 "slots" option of snd module. In the case above, specify like the 2128 following: 2129 2130 options snd slots=snd-interwave,snd-ens1371 2131 2132 Then, the first slot (#0) is reserved for snd-interwave driver, and 2133 the second (#1) for snd-ens1371. You can omit index option in each 2134 driver if slots option is used (although you can still have them at 2135 the same time as long as they don't conflict). 2136 2137 The slots option is especially useful for avoiding the possible 2138 hot-plugging and the resultant slot conflict. For example, in the 2139 case above again, the first two slots are already reserved. If any 2140 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or 2141 snd-ens1371, it will be assigned to the third or later slot. 2142 2143 When a module name is given with '!', the slot will be given for any 2144 modules but that name. For example, "slots=!snd-pcsp" will reserve 2145 the first slot for any modules but snd-pcsp. 2146 2147 2148 ALSA PCM devices to OSS devices mapping 2149 ======================================= 2150 2151 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 2152 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 2153 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 2154 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 2155 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 2156 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 2157 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 2158 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 2159 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 2160 2161 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means 2162 sound card number and second means device number. The ALSA devices 2163 have either 'c' or 'p' suffix indicating the direction, capture and 2164 playback, respectively. 2165 2166 Please note that the device mapping above may be varied via the module 2167 options of snd-pcm-oss module. 2168 2169 2170 Proc interfaces (/proc/asound) 2171 ============================== 2172 2173 /proc/asound/card#/pcm#[cp]/oss 2174 ------------------------------- 2175 String "erase" - erase all additional informations about OSS applications 2176 String "<app_name> <fragments> <fragment_size> [<options>]" 2177 2178 <app_name> - name of application with (higher priority) or without path 2179 <fragments> - number of fragments or zero if auto 2180 <fragment_size> - size of fragment in bytes or zero if auto 2181 <options> - optional parameters 2182 - disable the application tries to open a pcm device for 2183 this channel but does not want to use it. 2184 (Cause a bug or mmap needs) 2185 It's good for Quake etc... 2186 - direct don't use plugins 2187 - block force block mode (rvplayer) 2188 - non-block force non-block mode 2189 - whole-frag write only whole fragments (optimization affecting 2190 playback only) 2191 - no-silence do not fill silence ahead to avoid clicks 2192 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl 2193 instead of filled blocks 2194 2195 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss 2196 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss 2197 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss 2198 2199 2200 Early Buffer Allocation 2201 ======================= 2202 2203 Some drivers (e.g. hdsp) require the large contiguous buffers, and 2204 sometimes it's too late to find such spaces when the driver module is 2205 actually loaded due to memory fragmentation. You can pre-allocate the 2206 PCM buffers by loading snd-page-alloc module and write commands to its 2207 proc file in prior, for example, in the early boot stage like 2208 /etc/init.d/*.local scripts. 2209 2210 Reading the proc file /proc/drivers/snd-page-alloc shows the current 2211 usage of page allocation. In writing, you can send the following 2212 commands to the snd-page-alloc driver: 2213 2214 - add VENDOR DEVICE MASK SIZE BUFFERS 2215 2216 VENDOR and DEVICE are PCI vendor and device IDs. They take 2217 integer numbers (0x prefix is needed for the hex). 2218 MASK is the PCI DMA mask. Pass 0 if not restricted. 2219 SIZE is the size of each buffer to allocate. You can pass 2220 k and m suffix for KB and MB. The max number is 16MB. 2221 BUFFERS is the number of buffers to allocate. It must be greater 2222 than 0. The max number is 4. 2223 2224 - erase 2225 2226 This will erase the all pre-allocated buffers which are not in 2227 use. 2228 2229 2230 Links and Addresses 2231 =================== 2232 2233 ALSA project homepage 2234 http://www.alsa-project.org 2235 2236 Kernel Bugzilla 2237 http://bugzilla.kernel.org/ 2238 2239 ALSA Developers ML 2240 mailto:alsa-devel[AT]alsa-project[DOT]org 2241 2242 alsa-info.sh script 2243 http://www.alsa-project.org/alsa-info.sh
