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

998 The model name "genric" is treated as a special case. When this
999 model is given, the driver uses the generic codec parser without
1000 "codec-patch". It's sometimes good for testing and debugging.
1002 If the default configuration doesn't work and one of the above
1003 matches with your device, report it together with the PCI
1004 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
1005 ML (see the section "Links and Addresses").
1007 When CONFIG_SND_HDA_POWER_SAVE is set, two options, power_save and
1008 power_save_controller become available. power_save specifies the
1009 time to turn off the power automatically at idle status. When
1010 power_save_controller is true, the controller is also turned off.
1011 This might result in more obvious click noise at turning on/off.
1013 Note 2: If you get click noises on output, try the module option
1014 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
1015 register value without FIFO size correction as the current
1016 DMA pointer. position_fix=2 will make the driver to use
1017 the position buffer instead of reading SD_LPIB register.
1018 (Usually SD_LPLIB register is more accurate than the
1021 NB: If you get many "azx_get_response timeout" messages at
1022 loading, it's likely a problem of interrupts (e.g. ACPI irq
1023 routing). Try to boot with options like "pci=noacpi". Also, you
1024 can try "single_cmd=1" module option. This will switch the
1025 communication method between HDA controller and codecs to the
1026 single immediate commands instead of CORB/RIRB. Basically, the
1027 single command mode is provided only for BIOS, and you won't get
1028 unsolicited events, too. But, at least, this works independently
1029 from the irq. Remember this is a last resort, and should be
1030 avoided as much as possible...
1032 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
1033 On some hardwares, you may need to add a proper probe_mask option
1034 to avoid the "azx_get_response timeout" problem above, instead.
1035 This occurs when the access to non-existing or non-working codec slot
1036 (likely a modem one) causes a stall of the communication via HD-audio
1037 bus. You can see which codec slots are probed by enabling
1038 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
1039 proc files. Then limit the slots to probe by probe_mask option.
1040 For example, probe_mask=1 means to probe only the first slot, and
1041 probe_mask=4 means only the third slot.
1043 The power-management is supported.
1048 Module for RME Hammerfall DSP audio interface(s)
1050 This module supports multiple cards.
1052 Note: The firmware data can be automatically loaded via hotplug
1053 when CONFIG_FW_LOADER is set. Otherwise, you need to load
1054 the firmware via hdsploader utility included in alsa-tools
1056 The firmware data is found in alsa-firmware package.
1058 Note: snd-page-alloc module does the job which snd-hammerfall-mem
1059 module did formerly. It will allocate the buffers in advance
1060 when any HDSP cards are found. To make the buffer
1061 allocation sure, load snd-page-alloc module in the early
1062 stage of boot sequence. See "Early Buffer Allocation"

1405 buffer_top - specify buffer top address
1406 use_cache - 0 or 1 (disabled by default)
1407 vaio_hack - alias buffer_top=0x25a800
1408 reset_workaround - enable AC97 RESET workaround for some laptops
1409 reset_workaround2 - enable extended AC97 RESET workaround for some
1412 This module supports one chip and autoprobe.
1414 The power-management is supported.
1416 Note: on some notebooks the buffer address cannot be detected
1417 automatically, or causes hang-up during initialization.
1418 In such a case, specify the buffer top address explicitly via
1419 the buffer_top option.
1421 Sony F250: buffer_top=0x25a800
1422 Sony F270: buffer_top=0x272800
1423 The driver supports only ac97 codec. It's possible to force
1424 to initialize/use ac97 although it's not detected. In such a
1425 case, use force_ac97=1 option - but *NO* guarantee whether it
1428 Note: The NM256 chip can be linked internally with non-AC97
1429 codecs. This driver supports only the AC97 codec, and won't work
1430 with machines with other (most likely CS423x or OPL3SAx) chips,
1431 even though the device is detected in lspci. In such a case, try
1432 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1433 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1434 and proper hardware parameters in the case without ISA PnP.
1436 Note: some laptops need a workaround for AC97 RESET. For the
1437 known hardware like Dell Latitude LS and Sony PCG-F305, this
1438 workaround is enabled automatically. For other laptops with a
1439 hard freeze, you can try reset_workaround=1 option.
1441 Note: Dell Latitude CSx laptops have another problem regarding
1442 AC97 RESET. On these laptops, reset_workaround2 option is
1443 turned on as default. This option is worth to try if the
1444 previous reset_workaround option doesn't help.
1446 Note: This driver is really crappy. It's a porting from the
1447 OSS driver, which is a result of black-magic reverse engineering.
1448 The detection of codec will fail if the driver is loaded *after*
1449 X-server as described above. You might be able to force to load
1450 the module, but it may result in hang-up. Hence, make sure that
1451 you load this module *before* X if you encounter this kind of

1721 The below are options for wavefront_synth features:
1722 wf_raw - Assume that we need to boot the OS (default:no)
1723 If yes, then during driver loading, the state of the board is
1724 ignored, and we reset the board and load the firmware anyway.
1725 fx_raw - Assume that the FX process needs help (default:yes)
1726 If false, we'll leave the FX processor in whatever state it is
1727 when the driver is loaded. The default is to download the
1728 microprogram and associated coefficients to set it up for
1729 "default" operation, whatever that means.
1730 debug_default - Debug parameters for card initialization
1731 wait_usecs - How long to wait without sleeping, usecs
1733 This magic number seems to give pretty optimal throughput
1734 based on my limited experimentation.
1735 If you want to play around with it and find a better value, be
1736 my guest. Remember, the idea is to get a number that causes us
1737 to just busy wait for as many WaveFront commands as possible,
1738 without coming up with a number so large that we hog the whole
1740 Specifically, with this number, out of about 134,000 status
1741 waits, only about 250 result in a sleep.
1742 sleep_interval - How long to sleep when waiting for reply
1744 sleep_tries - How many times to try sleeping during a wait
1746 ospath - Pathname to processed ICS2115 OS firmware
1747 (default:wavefront.os)
1748 The path name of the ISC2115 OS firmware. In the recent
1749 version, it's handled via firmware loader framework, so it
1750 must be installed in the proper path, typically,
1752 reset_time - How long to wait for a reset to take effect
1754 ramcheck_time - How many seconds to wait for the RAM test
1756 osrun_time - How many seconds to wait for the ICS2115 OS
1759 This module supports multiple cards and ISA PnP.
1761 Note: the firmware file "wavefront.os" was located in the earlier
1762 version in /etc. Now it's loaded via firmware loader, and
1763 must be in the proper firmware path, such as /lib/firmware.
1764 Copy (or symlink) the file appropriately if you get an error
1765 regarding firmware downloading after upgrading the kernel.

1869 ac97_quirk - AC'97 workaround for strange hardware
1870 See "AC97 Quirk Option" section below.
1872 This module supports one chip and autoprobe.
1874 Note: on some SMP motherboards like MSI 694D the interrupts might
1875 not be generated properly. In such a case, please try to
1876 set the SMP (or MPS) version on BIOS to 1.1 instead of
1877 default value 1.4. Then the interrupt number will be
1878 assigned under 15. You might also upgrade your BIOS.
1880 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1881 channels as the first PCM. On these channels, up to 4
1882 streams can be played at the same time, and the controller
1883 can perform sample rate conversion with separate rates for
1885 As default (dxs_support = 0), 48k fixed rate is chosen
1886 except for the known devices since the output is often
1887 noisy except for 48k on some mother boards due to the
1889 Please try once dxs_support=5 and if it works on other
1890 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1891 know the PCI subsystem vendor/device id's (output of
1893 If dxs_support=5 does not work, try dxs_support=4; if it
1894 doesn't work too, try dxs_support=1. (dxs_support=1 is
1895 usually for old motherboards. The correct implemented
1896 board should work with 4 or 5.) If it still doesn't
1897 work and the default setting is ok, dxs_support=3 is the
1898 right choice. If the default setting doesn't work at all,
1899 try dxs_support=2 to disable the DXS channels.
1900 In any cases, please let us know the result and the
1901 subsystem vendor/device ids. See "Links and Addresses"
1904 Note: for the MPU401 on VIA823x, use snd-mpu401 driver
1905 additionally. The mpu_port option is for VIA686 chips only.
1907 The power-management is supported.
1909 Module snd-via82xx-modem
1910 ------------------------
1912 Module for VIA82xx AC97 modem

1940 ibl - Capture IBL size. (default = 0, minimum size)
1942 This module supports multiple cards.
1944 When the driver is compiled as a module and the hotplug firmware
1945 is supported, the firmware data is loaded via hotplug automatically.
1946 Install the necessary firmware files in alsa-firmware package.
1947 When no hotplug fw loader is available, you need to load the
1948 firmware via vxloader utility in alsa-tools package. To invoke
1949 vxloader automatically, add the following to /etc/modprobe.conf
1951 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1953 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1954 /etc/modules.conf, instead.)
1955 IBL size defines the interrupts period for PCM. The smaller size
1956 gives smaller latency but leads to more CPU consumption, too.
1957 The size is usually aligned to 126. As default (=0), the smallest
1958 size is chosen. The possible IBL values can be found in
1959 /proc/asound/cardX/vx-status proc file.
1961 The power-management is supported.
1966 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.
1968 ibl - Capture IBL size. (default = 0, minimum size)
1970 This module supports multiple cards. The module is compiled only when
1971 PCMCIA is supported on kernel.
1973 With the older 2.6.x kernel, to activate the driver via the card
1974 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1975 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1976 longer require a config file.
1978 When the driver is compiled as a module and the hotplug firmware
1979 is supported, the firmware data is loaded via hotplug automatically.
1980 Install the necessary firmware files in alsa-firmware package.
1981 When no hotplug fw loader is available, you need to load the
1982 firmware via vxloader utility in alsa-tools package.
1984 About capture IBL, see the description of snd-vx222 module.
1986 Note: snd-vxp440 driver is merged to snd-vxpocket driver since
1989 The power-management is supported.
1994 Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x).
1996 mpu_port - 0x300,0x330,0x332,0x334, 0 (disable) by default,
1997 1 (auto-detect for YMF744/754 only)
1998 fm_port - 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default
1999 1 (auto-detect for YMF744/754 only)
2000 joystick_port - 0x201,0x202,0x204,0x205, 0 (disable) by default,
2002 rear_switch - enable shared rear/line-in switch (bool)
2004 This module supports autoprobe and multiple chips.
2006 The power-management is supported.
2008 Module snd-pdaudiocf
2009 --------------------
2011 Module for Sound Core PDAudioCF sound card.
2013 The power-management is supported.
2019 The ac97_quirk option is used to enable/override the workaround for
2020 specific devices on drivers for on-board AC'97 controllers like
2021 snd-intel8x0. Some hardware have swapped output pins between Master
2022 and Headphone, or Surround (thanks to confusion of AC'97
2023 specifications from version to version :-)
2025 The driver provides the auto-detection of known problematic devices,
2026 but some might be unknown or wrongly detected. In such a case, pass
2027 the proper value with this option.
2029 The following strings are accepted:
2030 - default Don't override the default setting
2031 - none Disable the quirk
2032 - hp_only Bind Master and Headphone controls as a single control
2033 - swap_hp Swap headphone and master controls
2034 - swap_surround Swap master and surround controls
2035 - ad_sharing For AD1985, turn on OMS bit and use headphone
2036 - alc_jack For ALC65x, turn on the jack sense mode
2037 - inv_eapd Inverted EAPD implementation
2038 - mute_led Bind EAPD bit for turning on/off mute LED
2040 For backward compatibility, the corresponding integer value -1, 0,
2041 ... are accepted, too.
2043 For example, if "Master" volume control has no effect on your device
2044 but only "Headphone" does, pass ac97_quirk=hp_only module option.
2047 Configuring Non-ISAPNP Cards
2048 ============================
2050 When the kernel is configured with ISA-PnP support, the modules
2051 supporting the isapnp cards will have module options "isapnp".
2052 If this option is set, *only* the ISA-PnP devices will be probed.
2053 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
2054 together with the proper i/o and irq configuration.
2056 When the kernel is configured without ISA-PnP support, isapnp option
2057 will be not built in.
2060 Module Autoloading Support
2061 ==========================
2063 The ALSA drivers can be loaded automatically on demand by defining
2064 module aliases. The string 'snd-card-%1' is requested for ALSA native
2065 devices where %i is sound card number from zero to seven.
2067 To auto-load an ALSA driver for OSS services, define the string
2068 'sound-slot-%i' where %i means the slot number for OSS, which
2069 corresponds to the card index of ALSA. Usually, define this
2070 as the same card module.
2072 An example configuration for a single emu10k1 card is like below:
2073 ----- /etc/modprobe.conf
2074 alias snd-card-0 snd-emu10k1
2075 alias sound-slot-0 snd-emu10k1
2076 ----- /etc/modprobe.conf
2078 The available number of auto-loaded sound cards depends on the module
2079 option "cards_limit" of snd module. As default it's set to 1.
2080 To enable the auto-loading of multiple cards, specify the number of
2081 sound cards in that option.
2083 When multiple cards are available, it'd better to specify the index
2084 number for each card via module option, too, so that the order of
2085 cards is kept consistent.
2087 An example configuration for two sound cards is like below:
2089 ----- /etc/modprobe.conf
2091 options snd cards_limit=2
2092 alias snd-card-0 snd-interwave
2093 alias snd-card-1 snd-ens1371
2094 options snd-interwave index=0
2095 options snd-ens1371 index=1
2097 alias sound-slot-0 snd-interwave
2098 alias sound-slot-1 snd-ens1371
2099 ----- /etc/modprobe.conf
2101 In this example, the interwave card is always loaded as the first card
2102 (index 0) and ens1371 as the second (index 1).
2105 ALSA PCM devices to OSS devices mapping
2106 =======================================
2108 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2109 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2110 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2111 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2112 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2113 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2114 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2115 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2116 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2118 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2119 sound card number and second means device number. The ALSA devices
2120 have either 'c' or 'p' suffix indicating the direction, capture and
2121 playback, respectively.
2123 Please note that the device mapping above may be varied via the module
2124 options of snd-pcm-oss module.
2127 Proc interfaces (/proc/asound)
2128 ==============================
2130 /proc/asound/card#/pcm#[cp]/oss
2131 -------------------------------
2132 String "erase" - erase all additional informations about OSS applications
2133 String "<app_name> <fragments> <fragment_size> [<options>]"
2135 <app_name> - name of application with (higher priority) or without path
2136 <fragments> - number of fragments or zero if auto
2137 <fragment_size> - size of fragment in bytes or zero if auto
2138 <options> - optional parameters
2139 - disable the application tries to open a pcm device for
2140 this channel but does not want to use it.
2141 (Cause a bug or mmap needs)
2142 It's good for Quake etc...
2143 - direct don't use plugins
2144 - block force block mode (rvplayer)
2145 - non-block force non-block mode
2146 - whole-frag write only whole fragments (optimization affecting
2148 - no-silence do not fill silence ahead to avoid clicks
2149 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2150 instead of filled blocks
2152 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2153 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2154 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2157 Early Buffer Allocation
2158 =======================
2160 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2161 sometimes it's too late to find such spaces when the driver module is
2162 actually loaded due to memory fragmentation. You can pre-allocate the
2163 PCM buffers by loading snd-page-alloc module and write commands to its
2164 proc file in prior, for example, in the early boot stage like
2165 /etc/init.d/*.local scripts.
2167 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2168 usage of page allocation. In writing, you can send the following
2169 commands to the snd-page-alloc driver:
2171 - add VENDOR DEVICE MASK SIZE BUFFERS
2173 VENDOR and DEVICE are PCI vendor and device IDs. They take
2174 integer numbers (0x prefix is needed for the hex).
2175 MASK is the PCI DMA mask. Pass 0 if not restricted.
2176 SIZE is the size of each buffer to allocate. You can pass
2177 k and m suffix for KB and MB. The max number is 16MB.
2178 BUFFERS is the number of buffers to allocate. It must be greater
2179 than 0. The max number is 4.
2183 This will erase the all pre-allocated buffers which are not in
