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

982 The model name "genric" is treated as a special case. When this
983 model is given, the driver uses the generic codec parser without
984 "codec-patch". It's sometimes good for testing and debugging.
986 If the default configuration doesn't work and one of the above
987 matches with your device, report it together with the PCI
988 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
989 ML (see the section "Links and Addresses").
991 Note 2: If you get click noises on output, try the module option
992 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
993 register value without FIFO size correction as the current
994 DMA pointer. position_fix=2 will make the driver to use
995 the position buffer instead of reading SD_LPIB register.
996 (Usually SD_LPLIB register is more accurate than the
999 NB: If you get many "azx_get_response timeout" messages at
1000 loading, it's likely a problem of interrupts (e.g. ACPI irq
1001 routing). Try to boot with options like "pci=noacpi". Also, you
1002 can try "single_cmd=1" module option. This will switch the
1003 communication method between HDA controller and codecs to the
1004 single immediate commands instead of CORB/RIRB. Basically, the
1005 single command mode is provided only for BIOS, and you won't get
1006 unsolicited events, too. But, at least, this works independently
1007 from the irq. Remember this is a last resort, and should be
1008 avoided as much as possible...
1010 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
1011 On some hardwares, you may need to add a proper probe_mask option
1012 to avoid the "azx_get_response timeout" problem above, instead.
1013 This occurs when the access to non-existing or non-working codec slot
1014 (likely a modem one) causes a stall of the communication via HD-audio
1015 bus. You can see which codec slots are probed by enabling
1016 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
1017 proc files. Then limit the slots to probe by probe_mask option.
1018 For example, probe_mask=1 means to probe only the first slot, and
1019 probe_mask=4 means only the third slot.
1021 The power-management is supported.
1026 Module for RME Hammerfall DSP audio interface(s)
1028 This module supports multiple cards.
1030 Note: The firmware data can be automatically loaded via hotplug
1031 when CONFIG_FW_LOADER is set. Otherwise, you need to load
1032 the firmware via hdsploader utility included in alsa-tools
1034 The firmware data is found in alsa-firmware package.
1036 Note: snd-page-alloc module does the job which snd-hammerfall-mem
1037 module did formerly. It will allocate the buffers in advance
1038 when any HDSP cards are found. To make the buffer
1039 allocation sure, load snd-page-alloc module in the early
1040 stage of boot sequence. See "Early Buffer Allocation"

1386 reset_workaround - enable AC97 RESET workaround for some laptops
1387 reset_workaround2 - enable extended AC97 RESET workaround for some
1390 This module supports one chip and autoprobe.
1392 The power-management is supported.
1394 Note: on some notebooks the buffer address cannot be detected
1395 automatically, or causes hang-up during initialization.
1396 In such a case, specify the buffer top address explicitly via
1397 the buffer_top option.
1399 Sony F250: buffer_top=0x25a800
1400 Sony F270: buffer_top=0x272800
1401 The driver supports only ac97 codec. It's possible to force
1402 to initialize/use ac97 although it's not detected. In such a
1403 case, use force_ac97=1 option - but *NO* guarantee whether it
1406 Note: The NM256 chip can be linked internally with non-AC97
1407 codecs. This driver supports only the AC97 codec, and won't work
1408 with machines with other (most likely CS423x or OPL3SAx) chips,
1409 even though the device is detected in lspci. In such a case, try
1410 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1411 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1412 and proper hardware parameters in the case without ISA PnP.
1414 Note: some laptops need a workaround for AC97 RESET. For the
1415 known hardware like Dell Latitude LS and Sony PCG-F305, this
1416 workaround is enabled automatically. For other laptops with a
1417 hard freeze, you can try reset_workaround=1 option.
1419 Note: Dell Latitude CSx laptops have another problem regarding
1420 AC97 RESET. On these laptops, reset_workaround2 option is
1421 turned on as default. This option is worth to try if the
1422 previous reset_workaround option doesn't help.
1424 Note: This driver is really crappy. It's a porting from the
1425 OSS driver, which is a result of black-magic reverse engineering.
1426 The detection of codec will fail if the driver is loaded *after*
1427 X-server as described above. You might be able to force to load
1428 the module, but it may result in hang-up. Hence, make sure that
1429 you load this module *before* X if you encounter this kind of

1803 ac97_quirk - AC'97 workaround for strange hardware
1804 See "AC97 Quirk Option" section below.
1806 This module supports one chip and autoprobe.
1808 Note: on some SMP motherboards like MSI 694D the interrupts might
1809 not be generated properly. In such a case, please try to
1810 set the SMP (or MPS) version on BIOS to 1.1 instead of
1811 default value 1.4. Then the interrupt number will be
1812 assigned under 15. You might also upgrade your BIOS.
1814 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1815 channels as the first PCM. On these channels, up to 4
1816 streams can be played at the same time, and the controller
1817 can perform sample rate conversion with separate rates for
1819 As default (dxs_support = 0), 48k fixed rate is chosen
1820 except for the known devices since the output is often
1821 noisy except for 48k on some mother boards due to the
1823 Please try once dxs_support=5 and if it works on other
1824 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1825 know the PCI subsystem vendor/device id's (output of
1827 If dxs_support=5 does not work, try dxs_support=4; if it
1828 doesn't work too, try dxs_support=1. (dxs_support=1 is
1829 usually for old motherboards. The correct implemented
1830 board should work with 4 or 5.) If it still doesn't
1831 work and the default setting is ok, dxs_support=3 is the
1832 right choice. If the default setting doesn't work at all,
1833 try dxs_support=2 to disable the DXS channels.
1834 In any cases, please let us know the result and the
1835 subsystem vendor/device ids. See "Links and Addresses"
1838 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1874 ibl - Capture IBL size. (default = 0, minimum size)
1876 This module supports multiple cards.
1878 When the driver is compiled as a module and the hotplug firmware
1879 is supported, the firmware data is loaded via hotplug automatically.
1880 Install the necessary firmware files in alsa-firmware package.
1881 When no hotplug fw loader is available, you need to load the
1882 firmware via vxloader utility in alsa-tools package. To invoke
1883 vxloader automatically, add the following to /etc/modprobe.conf
1885 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1887 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1888 /etc/modules.conf, instead.)
1889 IBL size defines the interrupts period for PCM. The smaller size
1890 gives smaller latency but leads to more CPU consumption, too.
1891 The size is usually aligned to 126. As default (=0), the smallest
1892 size is chosen. The possible IBL values can be found in
1893 /proc/asound/cardX/vx-status proc file.
1895 The power-management is supported.
1900 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1902 ibl - Capture IBL size. (default = 0, minimum size)
1904 This module supports multiple cards. The module is compiled only when
1905 PCMCIA is supported on kernel.
1907 With the older 2.6.x kernel, to activate the driver via the card
1908 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1909 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1910 longer require a config file.
1912 When the driver is compiled as a module and the hotplug firmware
1913 is supported, the firmware data is loaded via hotplug automatically.
1914 Install the necessary firmware files in alsa-firmware package.
1915 When no hotplug fw loader is available, you need to load the
1916 firmware via vxloader utility in alsa-tools package.
1918 About capture IBL, see the description of snd-vx222 module.
1920 Note: snd-vxp440 driver is merged to snd-vxpocket driver since
1923 The power-management is supported.
1928 Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x).

1938 This module supports autoprobe and multiple chips.
1940 The power-management is supported.
1942 Module snd-pdaudiocf
1943 --------------------
1945 Module for Sound Core PDAudioCF sound card.
1947 The power-management is supported.
1953 The ac97_quirk option is used to enable/override the workaround for
1954 specific devices on drivers for on-board AC'97 controllers like
1955 snd-intel8x0. Some hardware have swapped output pins between Master
1956 and Headphone, or Surround (thanks to confusion of AC'97
1957 specifications from version to version :-)
1959 The driver provides the auto-detection of known problematic devices,
1960 but some might be unknown or wrongly detected. In such a case, pass
1961 the proper value with this option.
1963 The following strings are accepted:
1964 - default Don't override the default setting
1965 - none Disable the quirk
1966 - hp_only Bind Master and Headphone controls as a single control
1967 - swap_hp Swap headphone and master controls
1968 - swap_surround Swap master and surround controls
1969 - ad_sharing For AD1985, turn on OMS bit and use headphone
1970 - alc_jack For ALC65x, turn on the jack sense mode
1971 - inv_eapd Inverted EAPD implementation
1972 - mute_led Bind EAPD bit for turning on/off mute LED
1974 For backward compatibility, the corresponding integer value -1, 0,
1975 ... are accepted, too.
1977 For example, if "Master" volume control has no effect on your device
1978 but only "Headphone" does, pass ac97_quirk=hp_only module option.
1981 Configuring Non-ISAPNP Cards
1982 ============================
1984 When the kernel is configured with ISA-PnP support, the modules
1985 supporting the isapnp cards will have module options "isapnp".
1986 If this option is set, *only* the ISA-PnP devices will be probed.
1987 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
1988 together with the proper i/o and irq configuration.
1990 When the kernel is configured without ISA-PnP support, isapnp option
1991 will be not built in.
1994 Module Autoloading Support
1995 ==========================
1997 The ALSA drivers can be loaded automatically on demand by defining
1998 module aliases. The string 'snd-card-%1' is requested for ALSA native
1999 devices where %i is sound card number from zero to seven.
2001 To auto-load an ALSA driver for OSS services, define the string
2002 'sound-slot-%i' where %i means the slot number for OSS, which
2003 corresponds to the card index of ALSA. Usually, define this
2004 as the same card module.
2006 An example configuration for a single emu10k1 card is like below:
2007 ----- /etc/modprobe.conf
2008 alias snd-card-0 snd-emu10k1
2009 alias sound-slot-0 snd-emu10k1
2010 ----- /etc/modprobe.conf
2012 The available number of auto-loaded sound cards depends on the module
2013 option "cards_limit" of snd module. As default it's set to 1.
2014 To enable the auto-loading of multiple cards, specify the number of
2015 sound cards in that option.
2017 When multiple cards are available, it'd better to specify the index
2018 number for each card via module option, too, so that the order of
2019 cards is kept consistent.
2021 An example configuration for two sound cards is like below:
2023 ----- /etc/modprobe.conf
2025 options snd cards_limit=2
2026 alias snd-card-0 snd-interwave
2027 alias snd-card-1 snd-ens1371
2028 options snd-interwave index=0
2029 options snd-ens1371 index=1
2031 alias sound-slot-0 snd-interwave
2032 alias sound-slot-1 snd-ens1371
2033 ----- /etc/modprobe.conf
2035 In this example, the interwave card is always loaded as the first card
2036 (index 0) and ens1371 as the second (index 1).
2039 ALSA PCM devices to OSS devices mapping
2040 =======================================
2042 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2043 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2044 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2045 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2046 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2047 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2048 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2049 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2050 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2052 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2053 sound card number and second means device number. The ALSA devices
2054 have either 'c' or 'p' suffix indicating the direction, capture and
2055 playback, respectively.
2057 Please note that the device mapping above may be varied via the module
2058 options of snd-pcm-oss module.
2061 Proc interfaces (/proc/asound)
2062 ==============================
2064 /proc/asound/card#/pcm#[cp]/oss
2065 -------------------------------
2066 String "erase" - erase all additional informations about OSS applications
2067 String "<app_name> <fragments> <fragment_size> [<options>]"
2069 <app_name> - name of application with (higher priority) or without path
2070 <fragments> - number of fragments or zero if auto
2071 <fragment_size> - size of fragment in bytes or zero if auto
2072 <options> - optional parameters
2073 - disable the application tries to open a pcm device for
2074 this channel but does not want to use it.
2075 (Cause a bug or mmap needs)
2076 It's good for Quake etc...
2077 - direct don't use plugins
2078 - block force block mode (rvplayer)
2079 - non-block force non-block mode
2080 - whole-frag write only whole fragments (optimization affecting
2082 - no-silence do not fill silence ahead to avoid clicks
2083 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2084 instead of filled blocks
2086 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2087 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2088 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2091 Early Buffer Allocation
2092 =======================
2094 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2095 sometimes it's too late to find such spaces when the driver module is
2096 actually loaded due to memory fragmentation. You can pre-allocate the
2097 PCM buffers by loading snd-page-alloc module and write commands to its
2098 proc file in prior, for example, in the early boot stage like
2099 /etc/init.d/*.local scripts.
2101 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2102 usage of page allocation. In writing, you can send the following
2103 commands to the snd-page-alloc driver:
2105 - add VENDOR DEVICE MASK SIZE BUFFERS
2107 VENDOR and DEVICE are PCI vendor and device IDs. They take
2108 integer numbers (0x prefix is needed for the hex).
2109 MASK is the PCI DMA mask. Pass 0 if not restricted.
2110 SIZE is the size of each buffer to allocate. You can pass
2111 k and m suffix for KB and MB. The max number is 16MB.
2112 BUFFERS is the number of buffers to allocate. It must be greater
2113 than 0. The max number is 4.
2117 This will erase the all pre-allocated buffers which are not in
