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 64 Module snd-pcm-oss 65 ------------------ 66 67 The PCM OSS emulation module. 68 This module takes options which change the mapping of devices. 69 70 dsp_map - PCM device number maps assigned to the 1st OSS device. 71 - Default: 0 72 adsp_map - PCM device number maps assigned to the 2st OSS device. 73 - Default: 1 74 nonblock_open 75 - Don't block opening busy PCM devices. Default: 1 76 77 For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of 78 the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped 79 to PCM #0 of the card #0. 80 For changing the second or later card, specify the option with 81 commas, such like "dsp_map=0,1". 82 83 nonblock_open option is used to change the behavior of the PCM 84 regarding opening the device. When this option is non-zero, 85 opening a busy OSS PCM device won't be blocked but return 86 immediately with EAGAIN (just like O_NONBLOCK flag). 87 88 Module snd-rawmidi 89 ------------------ 90 91 This module takes options which change the mapping of devices. 92 similar to those of the snd-pcm-oss module. 93 94 midi_map - MIDI device number maps assigned to the 1st OSS device. 95 - Default: 0 96 amidi_map - MIDI device number maps assigned to the 2st OSS device. 97 - Default: 1 98 99 Common parameters for top sound card modules 100 -------------------------------------------- 101 102 Each of top level sound card module takes the following options. 103 104 index - index (slot #) of sound card 105 - Values: 0 through 31 or negative 106 - If nonnegative, assign that index number 107 - if negative, interpret as a bitmask of permissible 108 indices; the first free permitted index is assigned 109 - Default: -1 110 id - card ID (identifier or name) 111 - Can be up to 15 characters long 112 - Default: the card type 113 - A directory by this name is created under /proc/asound/ 114 containing information about the card 115 - This ID can be used instead of the index number in 116 identifying the card 117 enable - enable card 118 - Default: enabled, for PCI and ISA PnP cards 119 120 Module snd-adlib 121 ---------------- 122 123 Module for AdLib FM cards. 124 125 port - port # for OPL chip 126 127 This module supports multiple cards. It does not support autoprobe, so 128 the port must be specified. For actual AdLib FM cards it will be 0x388. 129 Note that this card does not have PCM support and no mixer; only FM 130 synthesis. 131 132 Make sure you have "sbiload" from the alsa-tools package available and, 133 after loading the module, find out the assigned ALSA sequencer port 134 number through "sbiload -l". Example output: 135 136 Port Client name Port name 137 64:0 OPL2 FM synth OPL2 FM Port 138 139 Load the std.sb and drums.sb patches also supplied by sbiload: 140 141 sbiload -p 64:0 std.sb drums.sb 142 143 If you use this driver to drive an OPL3, you can use std.o3 and drums.o3 144 instead. To have the card produce sound, use aplaymidi from alsa-utils: 145 146 aplaymidi -p 64:0 foo.mid 147 148 Module snd-ad1816a 149 ------------------ 150 151 Module for sound cards based on Analog Devices AD1816A/AD1815 ISA chips. 152 153 clockfreq - Clock frequency for AD1816A chip (default = 0, 33000Hz) 154 155 This module supports multiple cards, autoprobe and PnP. 156 157 Module snd-ad1848 158 ----------------- 159 160 Module for sound cards based on AD1848/AD1847/CS4248 ISA chips. 161 162 port - port # for AD1848 chip 163 irq - IRQ # for AD1848 chip 164 dma1 - DMA # for AD1848 chip (0,1,3) 165 166 This module supports multiple cards.

When this 1026 model is given, the driver uses the generic codec parser without 1027 "codec-patch". It's sometimes good for testing and debugging. 1028 1029 If the default configuration doesn't work and one of the above 1030 matches with your device, report it together with the PCI 1031 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel 1032 ML (see the section "Links and Addresses"). 1033 1034 power_save and power_save_controller options are for power-saving 1035 mode. See powersave.txt for details. 1036 1037 Note 2: If you get click noises on output, try the module option 1038 position_fix=1 or 2. position_fix=1 will use the SD_LPIB 1039 register value without FIFO size correction as the current 1040 DMA pointer. position_fix=2 will make the driver to use 1041 the position buffer instead of reading SD_LPIB register. 1042 (Usually SD_LPLIB register is more accurate than the 1043 position buffer.) 1044 1045 NB: If you get many "azx_get_response timeout" messages at 1046 loading, it's likely a problem of interrupts (e.g. ACPI irq 1047 routing). Try to boot with options like "pci=noacpi". Also, you 1048 can try "single_cmd=1" module option. This will switch the 1049 communication method between HDA controller and codecs to the 1050 single immediate commands instead of CORB/RIRB. Basically, the 1051 single command mode is provided only for BIOS, and you won't get 1052 unsolicited events, too. But, at least, this works independently 1053 from the irq. Remember this is a last resort, and should be 1054 avoided as much as possible... 1055 1056 MORE NOTES ON "azx_get_response timeout" PROBLEMS: 1057 On some hardwares, you may need to add a proper probe_mask option 1058 to avoid the "azx_get_response timeout" problem above, instead. 1059 This occurs when the access to non-existing or non-working codec slot 1060 (likely a modem one) causes a stall of the communication via HD-audio 1061 bus. You can see which codec slots are probed by enabling 1062 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec 1063 proc files. Then limit the slots to probe by probe_mask option. 1064 For example, probe_mask=1 means to probe only the first slot, and 1065 probe_mask=4 means only the third slot. 1066 1067 The power-management is supported. 1068 1069 Module snd-hdsp 1070 --------------- 1071 1072 Module for RME Hammerfall DSP audio interface(s) 1073 1074 This module supports multiple cards. 1075 1076 Note: The firmware data can be automatically loaded via hotplug 1077 when CONFIG_FW_LOADER is set. Otherwise, you need to load 1078 the firmware via hdsploader utility included in alsa-tools 1079 package. 1080 The firmware data is found in alsa-firmware package. 1081 1082 Note: snd-page-alloc module does the job which snd-hammerfall-mem 1083 module did formerly. It will allocate the buffers in advance 1084 when any HDSP cards are found. To make the buffer 1085 allocation sure, load snd-page-alloc module in the early 1086 stage of boot sequence.
