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

994 The model name "genric" is treated as a special case. When this
995 model is given, the driver uses the generic codec parser without
996 "codec-patch". It's sometimes good for testing and debugging.
998 If the default configuration doesn't work and one of the above
999 matches with your device, report it together with the PCI
1000 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
1001 ML (see the section "Links and Addresses").
1003 When CONFIG_SND_HDA_POWER_SAVE is set, two options, power_save and
1004 power_save_controller become available. power_save specifies the
1005 time to turn off the power automatically at idle status. When
1006 power_save_controller is true, the controller is also turned off.
1007 This might result in more obvious click noise at turning on/off.
1009 Note 2: If you get click noises on output, try the module option
1010 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
1011 register value without FIFO size correction as the current
1012 DMA pointer. position_fix=2 will make the driver to use
1013 the position buffer instead of reading SD_LPIB register.
1014 (Usually SD_LPLIB register is more accurate than the
1017 NB: If you get many "azx_get_response timeout" messages at
1018 loading, it's likely a problem of interrupts (e.g. ACPI irq
1019 routing). Try to boot with options like "pci=noacpi". Also, you
1020 can try "single_cmd=1" module option. This will switch the
1021 communication method between HDA controller and codecs to the
1022 single immediate commands instead of CORB/RIRB. Basically, the
1023 single command mode is provided only for BIOS, and you won't get
1024 unsolicited events, too. But, at least, this works independently
1025 from the irq. Remember this is a last resort, and should be
1026 avoided as much as possible...
1028 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
1029 On some hardwares, you may need to add a proper probe_mask option
1030 to avoid the "azx_get_response timeout" problem above, instead.
1031 This occurs when the access to non-existing or non-working codec slot
1032 (likely a modem one) causes a stall of the communication via HD-audio
1033 bus. You can see which codec slots are probed by enabling
1034 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
1035 proc files. Then limit the slots to probe by probe_mask option.
1036 For example, probe_mask=1 means to probe only the first slot, and
1037 probe_mask=4 means only the third slot.
1039 The power-management is supported.
1044 Module for RME Hammerfall DSP audio interface(s)
1046 This module supports multiple cards.
1048 Note: The firmware data can be automatically loaded via hotplug
1049 when CONFIG_FW_LOADER is set. Otherwise, you need to load
1050 the firmware via hdsploader utility included in alsa-tools
1052 The firmware data is found in alsa-firmware package.
1054 Note: snd-page-alloc module does the job which snd-hammerfall-mem
1055 module did formerly. It will allocate the buffers in advance
1056 when any HDSP cards are found. To make the buffer
1057 allocation sure, load snd-page-alloc module in the early
1058 stage of boot sequence. See "Early Buffer Allocation"

1404 reset_workaround - enable AC97 RESET workaround for some laptops
1405 reset_workaround2 - enable extended AC97 RESET workaround for some
1408 This module supports one chip and autoprobe.
1410 The power-management is supported.
1412 Note: on some notebooks the buffer address cannot be detected
1413 automatically, or causes hang-up during initialization.
1414 In such a case, specify the buffer top address explicitly via
1415 the buffer_top option.
1417 Sony F250: buffer_top=0x25a800
1418 Sony F270: buffer_top=0x272800
1419 The driver supports only ac97 codec. It's possible to force
1420 to initialize/use ac97 although it's not detected. In such a
1421 case, use force_ac97=1 option - but *NO* guarantee whether it
1424 Note: The NM256 chip can be linked internally with non-AC97
1425 codecs. This driver supports only the AC97 codec, and won't work
1426 with machines with other (most likely CS423x or OPL3SAx) chips,
1427 even though the device is detected in lspci. In such a case, try
1428 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1429 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1430 and proper hardware parameters in the case without ISA PnP.
1432 Note: some laptops need a workaround for AC97 RESET. For the
1433 known hardware like Dell Latitude LS and Sony PCG-F305, this
1434 workaround is enabled automatically. For other laptops with a
1435 hard freeze, you can try reset_workaround=1 option.
1437 Note: Dell Latitude CSx laptops have another problem regarding
1438 AC97 RESET. On these laptops, reset_workaround2 option is
1439 turned on as default. This option is worth to try if the
1440 previous reset_workaround option doesn't help.
1442 Note: This driver is really crappy. It's a porting from the
1443 OSS driver, which is a result of black-magic reverse engineering.
1444 The detection of codec will fail if the driver is loaded *after*
1445 X-server as described above. You might be able to force to load
1446 the module, but it may result in hang-up. Hence, make sure that
1447 you load this module *before* X if you encounter this kind of

1821 ac97_quirk - AC'97 workaround for strange hardware
1822 See "AC97 Quirk Option" section below.
1824 This module supports one chip and autoprobe.
1826 Note: on some SMP motherboards like MSI 694D the interrupts might
1827 not be generated properly. In such a case, please try to
1828 set the SMP (or MPS) version on BIOS to 1.1 instead of
1829 default value 1.4. Then the interrupt number will be
1830 assigned under 15. You might also upgrade your BIOS.
1832 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1833 channels as the first PCM. On these channels, up to 4
1834 streams can be played at the same time, and the controller
1835 can perform sample rate conversion with separate rates for
1837 As default (dxs_support = 0), 48k fixed rate is chosen
1838 except for the known devices since the output is often
1839 noisy except for 48k on some mother boards due to the
1841 Please try once dxs_support=5 and if it works on other
1842 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1843 know the PCI subsystem vendor/device id's (output of
1845 If dxs_support=5 does not work, try dxs_support=4; if it
1846 doesn't work too, try dxs_support=1. (dxs_support=1 is
1847 usually for old motherboards. The correct implemented
1848 board should work with 4 or 5.) If it still doesn't
1849 work and the default setting is ok, dxs_support=3 is the
1850 right choice. If the default setting doesn't work at all,
1851 try dxs_support=2 to disable the DXS channels.
1852 In any cases, please let us know the result and the
1853 subsystem vendor/device ids. See "Links and Addresses"
1856 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1892 ibl - Capture IBL size. (default = 0, minimum size)
1894 This module supports multiple cards.
1896 When the driver is compiled as a module and the hotplug firmware
1897 is supported, the firmware data is loaded via hotplug automatically.
1898 Install the necessary firmware files in alsa-firmware package.
1899 When no hotplug fw loader is available, you need to load the
1900 firmware via vxloader utility in alsa-tools package. To invoke
1901 vxloader automatically, add the following to /etc/modprobe.conf
1903 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1905 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1906 /etc/modules.conf, instead.)
1907 IBL size defines the interrupts period for PCM. The smaller size
1908 gives smaller latency but leads to more CPU consumption, too.
1909 The size is usually aligned to 126. As default (=0), the smallest
1910 size is chosen. The possible IBL values can be found in
1911 /proc/asound/cardX/vx-status proc file.
1913 The power-management is supported.
1918 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1920 ibl - Capture IBL size. (default = 0, minimum size)
1922 This module supports multiple cards. The module is compiled only when
1923 PCMCIA is supported on kernel.
1925 With the older 2.6.x kernel, to activate the driver via the card
1926 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1927 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1928 longer require a config file.
1930 When the driver is compiled as a module and the hotplug firmware
1931 is supported, the firmware data is loaded via hotplug automatically.
1932 Install the necessary firmware files in alsa-firmware package.
1933 When no hotplug fw loader is available, you need to load the
1934 firmware via vxloader utility in alsa-tools package.
1936 About capture IBL, see the description of snd-vx222 module.
1938 Note: snd-vxp440 driver is merged to snd-vxpocket driver since
1941 The power-management is supported.

1971 The ac97_quirk option is used to enable/override the workaround for
1972 specific devices on drivers for on-board AC'97 controllers like
1973 snd-intel8x0. Some hardware have swapped output pins between Master
1974 and Headphone, or Surround (thanks to confusion of AC'97
1975 specifications from version to version :-)
1977 The driver provides the auto-detection of known problematic devices,
1978 but some might be unknown or wrongly detected. In such a case, pass
1979 the proper value with this option.
1981 The following strings are accepted:
1982 - default Don't override the default setting
1983 - none Disable the quirk
1984 - hp_only Bind Master and Headphone controls as a single control

1986 - swap_surround Swap master and surround controls
1987 - ad_sharing For AD1985, turn on OMS bit and use headphone
1988 - alc_jack For ALC65x, turn on the jack sense mode
1989 - inv_eapd Inverted EAPD implementation
1990 - mute_led Bind EAPD bit for turning on/off mute LED
1992 For backward compatibility, the corresponding integer value -1, 0,
1993 ... are accepted, too.
1995 For example, if "Master" volume control has no effect on your device
1996 but only "Headphone" does, pass ac97_quirk=hp_only module option.
1999 Configuring Non-ISAPNP Cards
2000 ============================
2002 When the kernel is configured with ISA-PnP support, the modules
2003 supporting the isapnp cards will have module options "isapnp".
2004 If this option is set, *only* the ISA-PnP devices will be probed.
2005 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
2006 together with the proper i/o and irq configuration.
2008 When the kernel is configured without ISA-PnP support, isapnp option
2009 will be not built in.
2012 Module Autoloading Support
2013 ==========================
2015 The ALSA drivers can be loaded automatically on demand by defining
2016 module aliases. The string 'snd-card-%1' is requested for ALSA native
2017 devices where %i is sound card number from zero to seven.
2019 To auto-load an ALSA driver for OSS services, define the string
2020 'sound-slot-%i' where %i means the slot number for OSS, which
2021 corresponds to the card index of ALSA. Usually, define this
2022 as the same card module.
2024 An example configuration for a single emu10k1 card is like below:
2025 ----- /etc/modprobe.conf
2026 alias snd-card-0 snd-emu10k1
2027 alias sound-slot-0 snd-emu10k1
2028 ----- /etc/modprobe.conf
2030 The available number of auto-loaded sound cards depends on the module
2031 option "cards_limit" of snd module. As default it's set to 1.
2032 To enable the auto-loading of multiple cards, specify the number of
2033 sound cards in that option.
2035 When multiple cards are available, it'd better to specify the index
2036 number for each card via module option, too, so that the order of
2037 cards is kept consistent.
2039 An example configuration for two sound cards is like below:
2041 ----- /etc/modprobe.conf
2043 options snd cards_limit=2
2044 alias snd-card-0 snd-interwave
2045 alias snd-card-1 snd-ens1371
2046 options snd-interwave index=0
2047 options snd-ens1371 index=1
2049 alias sound-slot-0 snd-interwave
2050 alias sound-slot-1 snd-ens1371
2051 ----- /etc/modprobe.conf
2053 In this example, the interwave card is always loaded as the first card
2054 (index 0) and ens1371 as the second (index 1).
2057 ALSA PCM devices to OSS devices mapping
2058 =======================================
2060 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2061 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2062 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2063 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2064 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2065 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2066 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2067 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2068 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2070 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2071 sound card number and second means device number. The ALSA devices
2072 have either 'c' or 'p' suffix indicating the direction, capture and
2073 playback, respectively.
2075 Please note that the device mapping above may be varied via the module
2076 options of snd-pcm-oss module.
2079 Proc interfaces (/proc/asound)
2080 ==============================
2082 /proc/asound/card#/pcm#[cp]/oss
2083 -------------------------------
2084 String "erase" - erase all additional informations about OSS applications
2085 String "<app_name> <fragments> <fragment_size> [<options>]"
2087 <app_name> - name of application with (higher priority) or without path
2088 <fragments> - number of fragments or zero if auto
2089 <fragment_size> - size of fragment in bytes or zero if auto
2090 <options> - optional parameters
2091 - disable the application tries to open a pcm device for
2092 this channel but does not want to use it.
2093 (Cause a bug or mmap needs)
2094 It's good for Quake etc...
2095 - direct don't use plugins
2096 - block force block mode (rvplayer)
2097 - non-block force non-block mode
2098 - whole-frag write only whole fragments (optimization affecting
2100 - no-silence do not fill silence ahead to avoid clicks
2101 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2102 instead of filled blocks
2104 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2105 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2106 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2109 Early Buffer Allocation
2110 =======================
2112 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2113 sometimes it's too late to find such spaces when the driver module is
2114 actually loaded due to memory fragmentation. You can pre-allocate the
2115 PCM buffers by loading snd-page-alloc module and write commands to its
2116 proc file in prior, for example, in the early boot stage like
2117 /etc/init.d/*.local scripts.
2119 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2120 usage of page allocation. In writing, you can send the following
2121 commands to the snd-page-alloc driver:
2123 - add VENDOR DEVICE MASK SIZE BUFFERS
2125 VENDOR and DEVICE are PCI vendor and device IDs. They take
2126 integer numbers (0x prefix is needed for the hex).
2127 MASK is the PCI DMA mask. Pass 0 if not restricted.
2128 SIZE is the size of each buffer to allocate. You can pass
2129 k and m suffix for KB and MB. The max number is 16MB.
2130 BUFFERS is the number of buffers to allocate. It must be greater
2131 than 0. The max number is 4.
2135 This will erase the all pre-allocated buffers which are not in
