2 Advanced Linux Sound Architecture - Driver
3 ==========================================
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.
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.
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).
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.
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
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'.
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.
45 Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed.
50 The core ALSA module. It is used by all ALSA card drivers.
51 It takes the following options which have global effects.
53 major - major number for sound driver
56 - limiting card index for auto-loading (1-8)
58 - For auto-loading more than one card, specify this
59 option together with snd-card-X aliases.
65 The PCM OSS emulation module.
66 This module takes options which change the mapping of devices.
68 dsp_map - PCM device number maps assigned to the 1st OSS device.
70 adsp_map - PCM device number maps assigned to the 2st OSS device.
73 - Don't block opening busy PCM devices. Default: 1
75 For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of
76 the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped
77 to PCM #0 of the card #0.
78 For changing the second or later card, specify the option with
79 commas, such like "dsp_map=0,1".
81 nonblock_open option is used to change the behavior of the PCM
82 regarding opening the device. When this option is non-zero,
83 opening a busy OSS PCM device won't be blocked but return
84 immediately with EAGAIN (just like O_NONBLOCK flag).
89 This module takes options which change the mapping of devices.
90 similar to those of the snd-pcm-oss module.
92 midi_map - MIDI device number maps assigned to the 1st OSS device.
94 amidi_map - MIDI device number maps assigned to the 2st OSS device.
97 Common parameters for top sound card modules
98 --------------------------------------------
100 Each of top level sound card module takes the following options.
102 index - index (slot #) of sound card
103 - Values: 0 through 31 or negative
104 - If nonnegative, assign that index number
105 - if negative, interpret as a bitmask of permissible
106 indices; the first free permitted index is assigned
108 id - card ID (identifier or name)
109 - Can be up to 15 characters long
110 - Default: the card type
111 - A directory by this name is created under /proc/asound/
112 containing information about the card
113 - This ID can be used instead of the index number in
116 - Default: enabled, for PCI and ISA PnP cards
121 Module for AdLib FM cards.
123 port - port # for OPL chip
125 This module supports multiple cards. It does not support autoprobe, so
126 the port must be specified. For actual AdLib FM cards it will be 0x388.
127 Note that this card does not have PCM support and no mixer; only FM
130 Make sure you have "sbiload" from the alsa-tools package available and,
131 after loading the module, find out the assigned ALSA sequencer port
132 number through "sbiload -l". Example output:
134 Port Client name Port name
135 64:0 OPL2 FM synth OPL2 FM Port
137 Load the std.sb and drums.sb patches also supplied by sbiload:
139 sbiload -p 64:0 std.sb drums.sb
141 If you use this driver to drive an OPL3, you can use std.o3 and drums.o3
142 instead. To have the card produce sound, use aplaymidi from alsa-utils:
144 aplaymidi -p 64:0 foo.mid

987 The model name "genric" is treated as a special case. When this
988 model is given, the driver uses the generic codec parser without
989 "codec-patch". It's sometimes good for testing and debugging.
991 If the default configuration doesn't work and one of the above
992 matches with your device, report it together with the PCI
993 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
994 ML (see the section "Links and Addresses").
996 Note 2: If you get click noises on output, try the module option
997 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
998 register value without FIFO size correction as the current
999 DMA pointer. position_fix=2 will make the driver to use
1000 the position buffer instead of reading SD_LPIB register.
1001 (Usually SD_LPLIB register is more accurate than the
1004 NB: If you get many "azx_get_response timeout" messages at
1005 loading, it's likely a problem of interrupts (e.g. ACPI irq
1006 routing). Try to boot with options like "pci=noacpi". Also, you
1007 can try "single_cmd=1" module option. This will switch the
1008 communication method between HDA controller and codecs to the
1009 single immediate commands instead of CORB/RIRB. Basically, the
1010 single command mode is provided only for BIOS, and you won't get
1011 unsolicited events, too. But, at least, this works independently
1012 from the irq. Remember this is a last resort, and should be
1013 avoided as much as possible...
1015 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
1016 On some hardwares, you may need to add a proper probe_mask option
1017 to avoid the "azx_get_response timeout" problem above, instead.
1018 This occurs when the access to non-existing or non-working codec slot
1019 (likely a modem one) causes a stall of the communication via HD-audio
1020 bus. You can see which codec slots are probed by enabling
1021 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
1022 proc files. Then limit the slots to probe by probe_mask option.
1023 For example, probe_mask=1 means to probe only the first slot, and
1024 probe_mask=4 means only the third slot.
1026 The power-management is supported.
1031 Module for RME Hammerfall DSP audio interface(s)
1033 This module supports multiple cards.
1035 Note: The firmware data can be automatically loaded via hotplug
1036 when CONFIG_FW_LOADER is set. Otherwise, you need to load
1037 the firmware via hdsploader utility included in alsa-tools
1039 The firmware data is found in alsa-firmware package.
1041 Note: snd-page-alloc module does the job which snd-hammerfall-mem
1042 module did formerly. It will allocate the buffers in advance
1043 when any HDSP cards are found. To make the buffer
1044 allocation sure, load snd-page-alloc module in the early
1045 stage of boot sequence. See "Early Buffer Allocation"

1387 force_ac97 - 0 or 1 (disabled by default)
1388 buffer_top - specify buffer top address
1389 use_cache - 0 or 1 (disabled by default)
1390 vaio_hack - alias buffer_top=0x25a800
1391 reset_workaround - enable AC97 RESET workaround for some laptops
1392 reset_workaround2 - enable extended AC97 RESET workaround for some
1395 This module supports one chip and autoprobe.
1397 The power-management is supported.
1399 Note: on some notebooks the buffer address cannot be detected
1400 automatically, or causes hang-up during initialization.
1401 In such a case, specify the buffer top address explicitly via
1402 the buffer_top option.
1404 Sony F250: buffer_top=0x25a800
1405 Sony F270: buffer_top=0x272800
1406 The driver supports only ac97 codec. It's possible to force
1407 to initialize/use ac97 although it's not detected. In such a
1408 case, use force_ac97=1 option - but *NO* guarantee whether it
1411 Note: The NM256 chip can be linked internally with non-AC97
1412 codecs. This driver supports only the AC97 codec, and won't work
1413 with machines with other (most likely CS423x or OPL3SAx) chips,
1414 even though the device is detected in lspci. In such a case, try
1415 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1416 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1417 and proper hardware parameters in the case without ISA PnP.
1419 Note: some laptops need a workaround for AC97 RESET. For the
1420 known hardware like Dell Latitude LS and Sony PCG-F305, this
1421 workaround is enabled automatically. For other laptops with a
1422 hard freeze, you can try reset_workaround=1 option.
1424 Note: Dell Latitude CSx laptops have another problem regarding
1425 AC97 RESET. On these laptops, reset_workaround2 option is
1426 turned on as default. This option is worth to try if the
1427 previous reset_workaround option doesn't help.
1429 Note: This driver is really crappy. It's a porting from the
1430 OSS driver, which is a result of black-magic reverse engineering.
1431 The detection of codec will fail if the driver is loaded *after*
1432 X-server as described above. You might be able to force to load
1433 the module, but it may result in hang-up. Hence, make sure that
1434 you load this module *before* X if you encounter this kind of

1811 This module supports one chip and autoprobe.
1813 Note: on some SMP motherboards like MSI 694D the interrupts might
1814 not be generated properly. In such a case, please try to
1815 set the SMP (or MPS) version on BIOS to 1.1 instead of
1816 default value 1.4. Then the interrupt number will be
1817 assigned under 15. You might also upgrade your BIOS.
1819 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1820 channels as the first PCM. On these channels, up to 4
1821 streams can be played at the same time, and the controller
1822 can perform sample rate conversion with separate rates for
1824 As default (dxs_support = 0), 48k fixed rate is chosen
1825 except for the known devices since the output is often
1826 noisy except for 48k on some mother boards due to the
1828 Please try once dxs_support=5 and if it works on other
1829 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1830 know the PCI subsystem vendor/device id's (output of
1832 If dxs_support=5 does not work, try dxs_support=4; if it
1833 doesn't work too, try dxs_support=1. (dxs_support=1 is
1834 usually for old motherboards. The correct implemented
1835 board should work with 4 or 5.) If it still doesn't
1836 work and the default setting is ok, dxs_support=3 is the
1837 right choice. If the default setting doesn't work at all,
1838 try dxs_support=2 to disable the DXS channels.
1839 In any cases, please let us know the result and the
1840 subsystem vendor/device ids. See "Links and Addresses"
1843 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1879 ibl - Capture IBL size. (default = 0, minimum size)
1881 This module supports multiple cards.
1883 When the driver is compiled as a module and the hotplug firmware
1884 is supported, the firmware data is loaded via hotplug automatically.
1885 Install the necessary firmware files in alsa-firmware package.
1886 When no hotplug fw loader is available, you need to load the
1887 firmware via vxloader utility in alsa-tools package. To invoke
1888 vxloader automatically, add the following to /etc/modprobe.conf
1890 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1892 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1893 /etc/modules.conf, instead.)
1894 IBL size defines the interrupts period for PCM. The smaller size
1895 gives smaller latency but leads to more CPU consumption, too.
1896 The size is usually aligned to 126. As default (=0), the smallest
1897 size is chosen. The possible IBL values can be found in
1898 /proc/asound/cardX/vx-status proc file.
1900 The power-management is supported.
1905 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1907 ibl - Capture IBL size. (default = 0, minimum size)
1909 This module supports multiple cards. The module is compiled only when
1910 PCMCIA is supported on kernel.
1912 With the older 2.6.x kernel, to activate the driver via the card
1913 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1914 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1915 longer require a config file.
1917 When the driver is compiled as a module and the hotplug firmware
1918 is supported, the firmware data is loaded via hotplug automatically.
1919 Install the necessary firmware files in alsa-firmware package.
1920 When no hotplug fw loader is available, you need to load the
1921 firmware via vxloader utility in alsa-tools package.
1923 About capture IBL, see the description of snd-vx222 module.
1925 Note: snd-vxp440 driver is merged to snd-vxpocket driver since
1928 The power-management is supported.

1948 --------------------
1950 Module for Sound Core PDAudioCF sound card.
1952 The power-management is supported.
1958 The ac97_quirk option is used to enable/override the workaround for
1959 specific devices on drivers for on-board AC'97 controllers like
1960 snd-intel8x0. Some hardware have swapped output pins between Master
1961 and Headphone, or Surround (thanks to confusion of AC'97
1962 specifications from version to version :-)
1964 The driver provides the auto-detection of known problematic devices,
1965 but some might be unknown or wrongly detected. In such a case, pass
1966 the proper value with this option.
1968 The following strings are accepted:
1969 - default Don't override the default setting
1970 - none Disable the quirk
1971 - hp_only Bind Master and Headphone controls as a single control
1972 - swap_hp Swap headphone and master controls
1973 - swap_surround Swap master and surround controls
1974 - ad_sharing For AD1985, turn on OMS bit and use headphone
1975 - alc_jack For ALC65x, turn on the jack sense mode
1976 - inv_eapd Inverted EAPD implementation
1977 - mute_led Bind EAPD bit for turning on/off mute LED
1979 For backward compatibility, the corresponding integer value -1, 0,
1980 ... are accepted, too.
1982 For example, if "Master" volume control has no effect on your device
1983 but only "Headphone" does, pass ac97_quirk=hp_only module option.
1986 Configuring Non-ISAPNP Cards
1987 ============================
1989 When the kernel is configured with ISA-PnP support, the modules
1990 supporting the isapnp cards will have module options "isapnp".
1991 If this option is set, *only* the ISA-PnP devices will be probed.
1992 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
1993 together with the proper i/o and irq configuration.
1995 When the kernel is configured without ISA-PnP support, isapnp option
1996 will be not built in.
1999 Module Autoloading Support
2000 ==========================
2002 The ALSA drivers can be loaded automatically on demand by defining
2003 module aliases. The string 'snd-card-%1' is requested for ALSA native
2004 devices where %i is sound card number from zero to seven.
2006 To auto-load an ALSA driver for OSS services, define the string
2007 'sound-slot-%i' where %i means the slot number for OSS, which
2008 corresponds to the card index of ALSA. Usually, define this
2009 as the same card module.
2011 An example configuration for a single emu10k1 card is like below:
2012 ----- /etc/modprobe.conf
2013 alias snd-card-0 snd-emu10k1
2014 alias sound-slot-0 snd-emu10k1
2015 ----- /etc/modprobe.conf
2017 The available number of auto-loaded sound cards depends on the module
2018 option "cards_limit" of snd module. As default it's set to 1.
2019 To enable the auto-loading of multiple cards, specify the number of
2020 sound cards in that option.
2022 When multiple cards are available, it'd better to specify the index
2023 number for each card via module option, too, so that the order of
2024 cards is kept consistent.
2026 An example configuration for two sound cards is like below:
2028 ----- /etc/modprobe.conf
2030 options snd cards_limit=2
2031 alias snd-card-0 snd-interwave
2032 alias snd-card-1 snd-ens1371
2033 options snd-interwave index=0
2034 options snd-ens1371 index=1
2036 alias sound-slot-0 snd-interwave
2037 alias sound-slot-1 snd-ens1371
2038 ----- /etc/modprobe.conf
2040 In this example, the interwave card is always loaded as the first card
2041 (index 0) and ens1371 as the second (index 1).
2044 ALSA PCM devices to OSS devices mapping
2045 =======================================
2047 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2048 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2049 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2050 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2051 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2052 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2053 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2054 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2055 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2057 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2058 sound card number and second means device number. The ALSA devices
2059 have either 'c' or 'p' suffix indicating the direction, capture and
2060 playback, respectively.
2062 Please note that the device mapping above may be varied via the module
2063 options of snd-pcm-oss module.
2066 Proc interfaces (/proc/asound)
2067 ==============================
2069 /proc/asound/card#/pcm#[cp]/oss
2070 -------------------------------
2071 String "erase" - erase all additional informations about OSS applications
2072 String "<app_name> <fragments> <fragment_size> [<options>]"
2074 <app_name> - name of application with (higher priority) or without path
2075 <fragments> - number of fragments or zero if auto
2076 <fragment_size> - size of fragment in bytes or zero if auto
2077 <options> - optional parameters
2078 - disable the application tries to open a pcm device for
2079 this channel but does not want to use it.
2080 (Cause a bug or mmap needs)
2081 It's good for Quake etc...
2082 - direct don't use plugins
2083 - block force block mode (rvplayer)
2084 - non-block force non-block mode
2085 - whole-frag write only whole fragments (optimization affecting
2087 - no-silence do not fill silence ahead to avoid clicks
2088 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2089 instead of filled blocks
2091 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2092 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2093 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2096 Early Buffer Allocation
2097 =======================
2099 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2100 sometimes it's too late to find such spaces when the driver module is
2101 actually loaded due to memory fragmentation. You can pre-allocate the
2102 PCM buffers by loading snd-page-alloc module and write commands to its
2103 proc file in prior, for example, in the early boot stage like
2104 /etc/init.d/*.local scripts.
2106 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2107 usage of page allocation. In writing, you can send the following
2108 commands to the snd-page-alloc driver:
2110 - add VENDOR DEVICE MASK SIZE BUFFERS
2112 VENDOR and DEVICE are PCI vendor and device IDs. They take
2113 integer numbers (0x prefix is needed for the hex).
2114 MASK is the PCI DMA mask. Pass 0 if not restricted.
2115 SIZE is the size of each buffer to allocate. You can pass
2116 k and m suffix for KB and MB. The max number is 16MB.
2117 BUFFERS is the number of buffers to allocate. It must be greater
2118 than 0. The max number is 4.
2122 This will erase the all pre-allocated buffers which are not in
