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 863 position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF) 864 probe_mask - Bitmask to probe codecs (default = -1, meaning all slots) 865 When the bit 8 (0x100) is set, the lower 8 bits are used 866 as the "fixed" codec slots; i.e. the driver probes the 867 slots regardless what hardware reports back 868 probe_only - Only probing and no codec initialization (default=off); 869 Useful to check the initial codec status for debugging 870 bdl_pos_adj - Specifies the DMA IRQ timing delay in samples. 871 Passing -1 will make the driver to choose the appropriate 872 value based on the controller chip. 873 patch - Specifies the early "patch" files to modify the HD-audio 874 setup before initializing the codecs. This option is 875 available only when CONFIG_SND_HDA_PATCH_LOADER=y is set. 876 See HD-Audio.txt for details. 877 beep_mode - Selects the beep registration mode (0=off, 1=on, 2= 878 dynamic registration via mute switch on/off); the default 879 value is set via CONFIG_SND_HDA_INPUT_BEEP_MODE kconfig. 880 881 [Single (global) options] 882 single_cmd - Use single immediate commands to communicate with 883 codecs (for debugging only) 884 enable_msi - Enable Message Signaled Interrupt (MSI) (default = off) 885 power_save - Automatic power-saving timeout (in second, 0 = 886 disable) 887 power_save_controller - Reset HD-audio controller in power-saving mode 888 (default = on) 889 align_buffer_size - Force rounding of buffer/period sizes to multiples 890 of 128 bytes. This is more efficient in terms of memory 891 access but isn't required by the HDA spec and prevents 892 users from specifying exact period/buffer sizes. 893 (default = on) 894 snoop - Enable/disable snooping (default = on) 895 896 This module supports multiple cards and autoprobe. 897 898 See Documentation/sound/alsa/HD-Audio.txt for more details about 899 HD-audio driver. 900 901 Each codec may have a model table for different configurations. 902 If your machine isn't listed there, the default (usually minimal) 903 configuration is set up. You can pass "model=<name>" option to 904 specify a certain model in such a case. There are different 905 models depending on the codec chip. The list of available models 906 is found in HD-Audio-Models.txt 907 908 The model name "genric" is treated as a special case. When this 909 model is given, the driver uses the generic codec parser without 910 "codec-patch". It's sometimes good for testing and debugging. 911 912 If the default configuration doesn't work and one of the above 913 matches with your device, report it together with alsa-info.sh 914 output (with --no-upload option) to kernel bugzilla or alsa-devel 915 ML (see the section "Links and Addresses"). 916 917 power_save and power_save_controller options are for power-saving 918 mode. See powersave.txt for details. 919 920 Note 2: If you get click noises on output, try the module option 921 position_fix=1 or 2. position_fix=1 will use the SD_LPIB 922 register value without FIFO size correction as the current 923 DMA pointer. position_fix=2 will make the driver to use 924 the position buffer instead of reading SD_LPIB register. 925 (Usually SD_LPIB register is more accurate than the 926 position buffer.) 927 928 NB: If you get many "azx_get_response timeout" messages at 929 loading, it's likely a problem of interrupts (e.g. ACPI irq 930 routing). Try to boot with options like "pci=noacpi". Also, you 931 can try "single_cmd=1" module option. This will switch the 932 communication method between HDA controller and codecs to the 933 single immediate commands instead of CORB/RIRB. Basically, the 934 single command mode is provided only for BIOS, and you won't get 935 unsolicited events, too. But, at least, this works independently 936 from the irq. Remember this is a last resort, and should be 937 avoided as much as possible... 938 939 MORE NOTES ON "azx_get_response timeout" PROBLEMS: 940 On some hardwares, you may need to add a proper probe_mask option 941 to avoid the "azx_get_response timeout" problem above, instead. 942 This occurs when the access to non-existing or non-working codec slot 943 (likely a modem one) causes a stall of the communication via HD-audio 944 bus. You can see which codec slots are probed by enabling 945 CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec 946 proc files. Then limit the slots to probe by probe_mask option. 947 For example, probe_mask=1 means to probe only the first slot, and 948 probe_mask=4 means only the third slot. 949 950 The power-management is supported. 951 952 Module snd-hdsp 953 --------------- 954 955 Module for RME Hammerfall DSP audio interface(s) 956 957 This module supports multiple cards. 958 959 Note: The firmware data can be automatically loaded via hotplug 960 when CONFIG_FW_LOADER is set. Otherwise, you need to load 961 the firmware via hdsploader utility included in alsa-tools 962 package. 963 The firmware data is found in alsa-firmware package. 964 965 Note: snd-page-alloc module does the job which snd-hammerfall-mem 966 module did formerly. It will allocate the buffers in advance 967 when any HDSP cards are found. To make the buffer 968 allocation sure, load snd-page-alloc module in the early 969 stage of boot sequence.

Note that it has been discontinued, but the 1360 Voyetra Turtle Beach knowledge base entry for it is still available 1361 at 1362 http://www.turtlebeach.com 1363 1364 Module snd-msnd-pinnacle 1365 ------------------------ 1366 1367 Module for Turtle Beach MultiSound Pinnacle/Fiji soundcards. 1368 1369 io - Port # for pinnacle/fiji card 1370 irq - IRQ # for pinnalce/fiji card 1371 mem - Memory address (0xb0000, 0xc8000, 0xd0000, 0xd8000, 1372 0xe0000 or 0xe8000) 1373 write_ndelay - enable write ndelay (default = 1) 1374 calibrate_signal - calibrate signal (default = 0) 1375 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1376 1377 The driver requires firmware files "turtlebeach/pndspini.bin" and 1378 "turtlebeach/pndsperm.bin" in the proper firmware directory. 1379 1380 Module snd-mtpav 1381 ---------------- 1382 1383 Module for MOTU MidiTimePiece AV multiport MIDI (on the parallel 1384 port). 1385 1386 port - I/O port # for MTPAV (0x378,0x278, default=0x378) 1387 irq - IRQ # for MTPAV (7,5, default=7) 1388 hwports - number of supported hardware ports, default=8. 1389 1390 Module supports only 1 card. This module has no enable option. 1391 1392 Module snd-mts64 1393 ---------------- 1394 1395 Module for Ego Systems (ESI) Miditerminal 4140 1396 1397 This module supports multiple devices. 1398 Requires parport (CONFIG_PARPORT). 1399 1400 Module snd-nm256 1401 ---------------- 1402 1403 Module for NeoMagic NM256AV/ZX chips 1404 1405 playback_bufsize - max playback frame size in kB (4-128kB) 1406 capture_bufsize - max capture frame size in kB (4-128kB) 1407 force_ac97 - 0 or 1 (disabled by default) 1408 buffer_top - specify buffer top address 1409 use_cache - 0 or 1 (disabled by default) 1410 vaio_hack - alias buffer_top=0x25a800 1411 reset_workaround - enable AC97 RESET workaround for some laptops 1412 reset_workaround2 - enable extended AC97 RESET workaround for some 1413 other laptops 1414 1415 This module supports one chip and autoprobe. 1416 1417 The power-management is supported. 1418 1419 Note: on some notebooks the buffer address cannot be detected 1420 automatically, or causes hang-up during initialization. 1421 In such a case, specify the buffer top address explicitly via 1422 the buffer_top option. 1423 For example, 1424 Sony F250: buffer_top=0x25a800 1425 Sony F270: buffer_top=0x272800 1426 The driver supports only ac97 codec. It's possible to force 1427 to initialize/use ac97 although it's not detected. In such a 1428 case, use force_ac97=1 option - but *NO* guarantee whether it 1429 works! 1430 1431 Note: The NM256 chip can be linked internally with non-AC97 1432 codecs. This driver supports only the AC97 codec, and won't work 1433 with machines with other (most likely CS423x or OPL3SAx) chips, 1434 even though the device is detected in lspci. In such a case, try 1435 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP 1436 but some doesn't have ISA PnP. You'll need to specify isapnp=0 1437 and proper hardware parameters in the case without ISA PnP. 1438 1439 Note: some laptops need a workaround for AC97 RESET. For the 1440 known hardware like Dell Latitude LS and Sony PCG-F305, this 1441 workaround is enabled automatically. For other laptops with a 1442 hard freeze, you can try reset_workaround=1 option. 1443 1444 Note: Dell Latitude CSx laptops have another problem regarding 1445 AC97 RESET. On these laptops, reset_workaround2 option is 1446 turned on as default. This option is worth to try if the 1447 previous reset_workaround option doesn't help. 1448 1449 Note: This driver is really crappy. It's a porting from the 1450 OSS driver, which is a result of black-magic reverse engineering. 1451 The detection of codec will fail if the driver is loaded *after* 1452 X-server as described above. You might be able to force to load 1453 the module, but it may result in hang-up. Hence, make sure that 1454 you load this module *before* X if you encounter this kind of 1455 problem. 1456 1457 Module snd-opl3sa2 1458 ------------------ 1459 1460 Module for Yamaha OPL3-SA2/SA3 sound cards. 1461 1462 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default) 1463 1464 with isapnp=0, the following options are available: 1465 1466 port - control port # for OPL3-SA chip (0x370) 1467 sb_port - SB port # for OPL3-SA chip (0x220,0x240) 1468 wss_port - WSS port # for OPL3-SA chip (0x530,0xe80,0xf40,0x604) 1469 midi_port - port # for MPU-401 UART (0x300,0x330), -1 = disable 1470 fm_port - FM port # for OPL3-SA chip (0x388), -1 = disable 1471 irq - IRQ # for OPL3-SA chip (5,7,9,10) 1472 dma1 - first DMA # for Yamaha OPL3-SA chip (0,1,3) 1473 dma2 - second DMA # for Yamaha OPL3-SA chip (0,1,3), -1 = disable 1474 1475 This module supports multiple cards and ISA PnP.

Changing via sysfs has no sanity 1908 check. 1909 NB: async_unlink=0 would cause Oops. It remains just for 1910 debugging purpose (if any). 1911 NB: ignore_ctl_error=1 may help when you get an error at accessing 1912 the mixer element such as URB error -22. This happens on some 1913 buggy USB device or the controller. 1914 1915 Module snd-usb-caiaq 1916 -------------------- 1917 1918 Module for caiaq UB audio interfaces, 1919 * Native Instruments RigKontrol2 1920 * Native Instruments Kore Controller 1921 * Native Instruments Audio Kontrol 1 1922 * Native Instruments Audio 8 DJ 1923 1924 This module supports multiple devices, autoprobe and hotplugging. 1925 1926 Module snd-usb-usx2y 1927 -------------------- 1928 1929 Module for Tascam USB US-122, US-224 and US-428 devices. 1930 1931 This module supports multiple devices, autoprobe and hotplugging. 1932 1933 Note: you need to load the firmware via usx2yloader utility included 1934 in alsa-tools and alsa-firmware packages. 1935 1936 Module snd-via82xx 1937 ------------------ 1938 1939 Module for AC'97 motherboards based on VIA 82C686A/686B, 8233, 1940 8233A, 8233C, 8235, 8237 (south) bridge. 1941 1942 mpu_port - 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup 1943 [VIA686A/686B only] 1944 joystick - Enable joystick (default off) [VIA686A/686B only] 1945 ac97_clock - AC'97 codec clock base (default 48000Hz) 1946 dxs_support - support DXS channels, 1947 0 = auto (default), 1 = enable, 2 = disable, 1948 3 = 48k only, 4 = no VRA, 5 = enable any sample 1949 rate and different sample rates on different 1950 channels 1951 [VIA8233/C, 8235, 8237 only] 1952 ac97_quirk - AC'97 workaround for strange hardware 1953 See "AC97 Quirk Option" section below. 1954 1955 This module supports one chip and autoprobe. 1956 1957 Note: on some SMP motherboards like MSI 694D the interrupts might 1958 not be generated properly. In such a case, please try to 1959 set the SMP (or MPS) version on BIOS to 1.1 instead of 1960 default value 1.4. Then the interrupt number will be 1961 assigned under 15. You might also upgrade your BIOS. 1962 1963 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) 1964 channels as the first PCM. On these channels, up to 4 1965 streams can be played at the same time, and the controller 1966 can perform sample rate conversion with separate rates for 1967 each channel. 1968 As default (dxs_support = 0), 48k fixed rate is chosen 1969 except for the known devices since the output is often 1970 noisy except for 48k on some mother boards due to the 1971 bug of BIOS. 1972 Please try once dxs_support=5 and if it works on other 1973 sample rates (e.g. 44.1kHz of mp3 playback), please let us 1974 know the PCI subsystem vendor/device id's (output of 1975 "lspci -nv"). 1976 If dxs_support=5 does not work, try dxs_support=4; if it 1977 doesn't work too, try dxs_support=1. (dxs_support=1 is 1978 usually for old motherboards. The correct implemented 1979 board should work with 4 or 5.) If it still doesn't 1980 work and the default setting is ok, dxs_support=3 is the 1981 right choice. If the default setting doesn't work at all, 1982 try dxs_support=2 to disable the DXS channels. 1983 In any cases, please let us know the result and the 1984 subsystem vendor/device ids. See "Links and Addresses" 1985 below. 1986 1987 Note: for the MPU401 on VIA823x, use snd-mpu401 driver 1988 additionally. The mpu_port option is for VIA686 chips only. 1989 1990 The power-management is supported. 1991 1992 Module snd-via82xx-modem 1993 ------------------------ 1994 1995 Module for VIA82xx AC97 modem 1996 1997 ac97_clock - AC'97 codec clock base (default 48000Hz) 1998 1999 This module supports one card and autoprobe. 2000 2001 Note: The default index value of this module is -2, i.e. the first 2002 slot is excluded. 2003 2004 The power-management is supported. 2005 2006 Module snd-virmidi 2007 ------------------ 2008 2009 Module for virtual rawmidi devices. 2010 This module creates virtual rawmidi devices which communicate 2011 to the corresponding ALSA sequencer ports. 2012 2013 midi_devs - MIDI devices # (1-4, default=4) 2014 2015 This module supports multiple cards. 2016 2017 Module snd-virtuoso 2018 ------------------- 2019 2020 Module for sound cards based on the Asus AV66/AV100/AV200 chips, 2021 i.e., Xonar D1, DX, D2, D2X, DS, Essence ST (Deluxe), Essence STX, 2022 HDAV1.3 (Deluxe), and HDAV1.3 Slim. 2023 2024 This module supports autoprobe and multiple cards. 2025 2026 Module snd-vx222 2027 ---------------- 2028 2029 Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards. 2030 2031 mic - Enable Microphone on V222 Mic (NYI) 2032 ibl - Capture IBL size. (default = 0, minimum size) 2033 2034 This module supports multiple cards. 2035 2036 When the driver is compiled as a module and the hotplug firmware 2037 is supported, the firmware data is loaded via hotplug automatically. 2038 Install the necessary firmware files in alsa-firmware package. 2039 When no hotplug fw loader is available, you need to load the 2040 firmware via vxloader utility in alsa-tools package. To invoke 2041 vxloader automatically, add the following to /etc/modprobe.conf 2042 2043 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader 2044 2045 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to 2046 /etc/modules.conf, instead.) 2047 IBL size defines the interrupts period for PCM. The smaller size 2048 gives smaller latency but leads to more CPU consumption, too. 2049 The size is usually aligned to 126. As default (=0), the smallest 2050 size is chosen. The possible IBL values can be found in 2051 /proc/asound/cardX/vx-status proc file. 2052 2053 The power-management is supported. 2054 2055 Module snd-vxpocket 2056 ------------------- 2057 2058 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards. 2059 2060 ibl - Capture IBL size. (default = 0, minimum size) 2061 2062 This module supports multiple cards. The module is compiled only when 2063 PCMCIA is supported on kernel. 2064 2065 With the older 2.6.x kernel, to activate the driver via the card 2066 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the 2067 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no 2068 longer require a config file. 2069 2070 When the driver is compiled as a module and the hotplug firmware 2071 is supported, the firmware data is loaded via hotplug automatically. 2072 Install the necessary firmware files in alsa-firmware package. 2073 When no hotplug fw loader is available, you need to load the 2074 firmware via vxloader utility in alsa-tools package. 2075 2076 About capture IBL, see the description of snd-vx222 module. 2077 2078 Note: snd-vxp440 driver is merged to snd-vxpocket driver since 2079 ALSA 1.0.10. 2080 2081 The power-management is supported. 2082 2083 Module snd-ymfpci 2084 ----------------- 2085 2086 Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x). 2087 2088 mpu_port - 0x300,0x330,0x332,0x334, 0 (disable) by default, 2089 1 (auto-detect for YMF744/754 only) 2090 fm_port - 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default 2091 1 (auto-detect for YMF744/754 only) 2092 joystick_port - 0x201,0x202,0x204,0x205, 0 (disable) by default, 2093 1 (auto-detect) 2094 rear_switch - enable shared rear/line-in switch (bool) 2095 2096 This module supports autoprobe and multiple chips. 2097 2098 The power-management is supported. 2099 2100 Module snd-pdaudiocf 2101 -------------------- 2102 2103 Module for Sound Core PDAudioCF sound card. 2104 2105 The power-management is supported. 2106 2107 2108 AC97 Quirk Option 2109 ================= 2110 2111 The ac97_quirk option is used to enable/override the workaround for 2112 specific devices on drivers for on-board AC'97 controllers like 2113 snd-intel8x0. Some hardware have swapped output pins between Master 2114 and Headphone, or Surround (thanks to confusion of AC'97 2115 specifications from version to version :-) 2116 2117 The driver provides the auto-detection of known problematic devices, 2118 but some might be unknown or wrongly detected. In such a case, pass 2119 the proper value with this option. 2120 2121 The following strings are accepted: 2122 - default Don't override the default setting 2123 - none Disable the quirk 2124 - hp_only Bind Master and Headphone controls as a single control 2125 - swap_hp Swap headphone and master controls 2126 - swap_surround Swap master and surround controls 2127 - ad_sharing For AD1985, turn on OMS bit and use headphone 2128 - alc_jack For ALC65x, turn on the jack sense mode 2129 - inv_eapd Inverted EAPD implementation 2130 - mute_led Bind EAPD bit for turning on/off mute LED 2131 2132 For backward compatibility, the corresponding integer value -1, 0, 2133 ... are accepted, too. 2134 2135 For example, if "Master" volume control has no effect on your device 2136 but only "Headphone" does, pass ac97_quirk=hp_only module option. 2137 2138 2139 Configuring Non-ISAPNP Cards 2140 ============================ 2141 2142 When the kernel is configured with ISA-PnP support, the modules 2143 supporting the isapnp cards will have module options "isapnp". 2144 If this option is set, *only* the ISA-PnP devices will be probed. 2145 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option 2146 together with the proper i/o and irq configuration. 2147 2148 When the kernel is configured without ISA-PnP support, isapnp option 2149 will be not built in. 2150 2151 2152 Module Autoloading Support 2153 ========================== 2154 2155 The ALSA drivers can be loaded automatically on demand by defining 2156 module aliases. The string 'snd-card-%1' is requested for ALSA native 2157 devices where %i is sound card number from zero to seven. 2158 2159 To auto-load an ALSA driver for OSS services, define the string 2160 'sound-slot-%i' where %i means the slot number for OSS, which 2161 corresponds to the card index of ALSA. Usually, define this 2162 as the same card module. 2163 2164 An example configuration for a single emu10k1 card is like below: 2165 ----- /etc/modprobe.conf 2166 alias snd-card-0 snd-emu10k1 2167 alias sound-slot-0 snd-emu10k1 2168 ----- /etc/modprobe.conf 2169 2170 The available number of auto-loaded sound cards depends on the module 2171 option "cards_limit" of snd module. As default it's set to 1. 2172 To enable the auto-loading of multiple cards, specify the number of 2173 sound cards in that option. 2174 2175 When multiple cards are available, it'd better to specify the index 2176 number for each card via module option, too, so that the order of 2177 cards is kept consistent. 2178 2179 An example configuration for two sound cards is like below: 2180 2181 ----- /etc/modprobe.conf 2182 # ALSA portion 2183 options snd cards_limit=2 2184 alias snd-card-0 snd-interwave 2185 alias snd-card-1 snd-ens1371 2186 options snd-interwave index=0 2187 options snd-ens1371 index=1 2188 # OSS/Free portion 2189 alias sound-slot-0 snd-interwave 2190 alias sound-slot-1 snd-ens1371 2191 ----- /etc/modprobe.conf 2192 2193 In this example, the interwave card is always loaded as the first card 2194 (index 0) and ens1371 as the second (index 1). 2195 2196 Alternative (and new) way to fixate the slot assignment is to use 2197 "slots" option of snd module. In the case above, specify like the 2198 following: 2199 2200 options snd slots=snd-interwave,snd-ens1371 2201 2202 Then, the first slot (#0) is reserved for snd-interwave driver, and 2203 the second (#1) for snd-ens1371. You can omit index option in each 2204 driver if slots option is used (although you can still have them at 2205 the same time as long as they don't conflict). 2206 2207 The slots option is especially useful for avoiding the possible 2208 hot-plugging and the resultant slot conflict. For example, in the 2209 case above again, the first two slots are already reserved. If any 2210 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or 2211 snd-ens1371, it will be assigned to the third or later slot. 2212 2213 When a module name is given with '!', the slot will be given for any 2214 modules but that name. For example, "slots=!snd-pcsp" will reserve 2215 the first slot for any modules but snd-pcsp. 2216 2217 2218 ALSA PCM devices to OSS devices mapping 2219 ======================================= 2220 2221 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 2222 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 2223 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 2224 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 2225 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 2226 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 2227 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 2228 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 2229 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 2230 2231 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means 2232 sound card number and second means device number. The ALSA devices 2233 have either 'c' or 'p' suffix indicating the direction, capture and 2234 playback, respectively. 2235 2236 Please note that the device mapping above may be varied via the module 2237 options of snd-pcm-oss module. 2238 2239 2240 Proc interfaces (/proc/asound) 2241 ============================== 2242 2243 /proc/asound/card#/pcm#[cp]/oss 2244 ------------------------------- 2245 String "erase" - erase all additional information about OSS applications 2246 String "<app_name> <fragments> <fragment_size> [<options>]" 2247 2248 <app_name> - name of application with (higher priority) or without path 2249 <fragments> - number of fragments or zero if auto 2250 <fragment_size> - size of fragment in bytes or zero if auto 2251 <options> - optional parameters 2252 - disable the application tries to open a pcm device for 2253 this channel but does not want to use it. 2254 (Cause a bug or mmap needs) 2255 It's good for Quake etc... 2256 - direct don't use plugins 2257 - block force block mode (rvplayer) 2258 - non-block force non-block mode 2259 - whole-frag write only whole fragments (optimization affecting 2260 playback only) 2261 - no-silence do not fill silence ahead to avoid clicks 2262 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl 2263 instead of filled blocks 2264 2265 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss 2266 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss 2267 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss 2268 2269 2270 Early Buffer Allocation 2271 ======================= 2272 2273 Some drivers (e.g. hdsp) require the large contiguous buffers, and 2274 sometimes it's too late to find such spaces when the driver module is 2275 actually loaded due to memory fragmentation. You can pre-allocate the 2276 PCM buffers by loading snd-page-alloc module and write commands to its 2277 proc file in prior, for example, in the early boot stage like 2278 /etc/init.d/*.local scripts. 2279 2280 Reading the proc file /proc/drivers/snd-page-alloc shows the current 2281 usage of page allocation. In writing, you can send the following 2282 commands to the snd-page-alloc driver: 2283 2284 - add VENDOR DEVICE MASK SIZE BUFFERS 2285 2286 VENDOR and DEVICE are PCI vendor and device IDs. They take 2287 integer numbers (0x prefix is needed for the hex). 2288 MASK is the PCI DMA mask. Pass 0 if not restricted. 2289 SIZE is the size of each buffer to allocate. You can pass 2290 k and m suffix for KB and MB. The max number is 16MB. 2291 BUFFERS is the number of buffers to allocate. It must be greater 2292 than 0. The max number is 4. 2293 2294 - erase 2295 2296 This will erase the all pre-allocated buffers which are not in 2297 use. 2298 2299 2300 Links and Addresses 2301 =================== 2302 2303 ALSA project homepage 2304 http://www.alsa-project.org 2305 2306 Kernel Bugzilla 2307 http://bugzilla.kernel.org/ 2308 2309 ALSA Developers ML 2310 mailto:alsa-devel@alsa-project.org 2311 2312 alsa-info.sh script 2313 http://www.alsa-project.org/alsa-info.sh
