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.
60 slots - Reserve the slot index for the given driver.
61 This option takes multiple strings.
62 See "Module Autoloading Support" section for details.
67 The PCM OSS emulation module.
68 This module takes options which change the mapping of devices.
70 dsp_map - PCM device number maps assigned to the 1st OSS device.
72 adsp_map - PCM device number maps assigned to the 2st OSS device.
75 - Don't block opening busy PCM devices. Default: 1
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".
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).
91 This module takes options which change the mapping of devices.
92 similar to those of the snd-pcm-oss module.
94 midi_map - MIDI device number maps assigned to the 1st OSS device.
96 amidi_map - MIDI device number maps assigned to the 2st OSS device.
99 Common parameters for top sound card modules
100 --------------------------------------------
102 Each of top level sound card module takes the following options.
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
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
118 - Default: enabled, for PCI and ISA PnP cards
123 Module for AdLib FM cards.
125 port - port # for OPL chip
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
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:
136 Port Client name Port name
137 64:0 OPL2 FM synth OPL2 FM Port
139 Load the std.sb and drums.sb patches also supplied by sbiload:
141 sbiload -p 64:0 std.sb drums.sb
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:
146 aplaymidi -p 64:0 foo.mid

989 The model name "genric" is treated as a special case. When this
990 model is given, the driver uses the generic codec parser without
991 "codec-patch". It's sometimes good for testing and debugging.
993 If the default configuration doesn't work and one of the above
994 matches with your device, report it together with the PCI
995 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
996 ML (see the section "Links and Addresses").
998 power_save and power_save_controller options are for power-saving
999 mode. See powersave.txt for details.
1001 Note 2: If you get click noises on output, try the module option
1002 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
1003 register value without FIFO size correction as the current
1004 DMA pointer. position_fix=2 will make the driver to use
1005 the position buffer instead of reading SD_LPIB register.
1006 (Usually SD_LPLIB register is more accurate than the
1009 NB: If you get many "azx_get_response timeout" messages at
1010 loading, it's likely a problem of interrupts (e.g. ACPI irq
1011 routing). Try to boot with options like "pci=noacpi". Also, you
1012 can try "single_cmd=1" module option. This will switch the
1013 communication method between HDA controller and codecs to the
1014 single immediate commands instead of CORB/RIRB. Basically, the
1015 single command mode is provided only for BIOS, and you won't get
1016 unsolicited events, too. But, at least, this works independently
1017 from the irq. Remember this is a last resort, and should be
1018 avoided as much as possible...
1020 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
1021 On some hardwares, you may need to add a proper probe_mask option
1022 to avoid the "azx_get_response timeout" problem above, instead.
1023 This occurs when the access to non-existing or non-working codec slot
1024 (likely a modem one) causes a stall of the communication via HD-audio
1025 bus. You can see which codec slots are probed by enabling
1026 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
1027 proc files. Then limit the slots to probe by probe_mask option.
1028 For example, probe_mask=1 means to probe only the first slot, and
1029 probe_mask=4 means only the third slot.
1031 The power-management is supported.
1036 Module for RME Hammerfall DSP audio interface(s)
1038 This module supports multiple cards.
1040 Note: The firmware data can be automatically loaded via hotplug
1041 when CONFIG_FW_LOADER is set. Otherwise, you need to load
1042 the firmware via hdsploader utility included in alsa-tools

1046 Note: snd-page-alloc module does the job which snd-hammerfall-mem
1047 module did formerly. It will allocate the buffers in advance
1048 when any HDSP cards are found. To make the buffer
1049 allocation sure, load snd-page-alloc module in the early
1050 stage of boot sequence. See "Early Buffer Allocation"

1408 In such a case, specify the buffer top address explicitly via
1409 the buffer_top option.
1411 Sony F250: buffer_top=0x25a800
1412 Sony F270: buffer_top=0x272800
1413 The driver supports only ac97 codec. It's possible to force
1414 to initialize/use ac97 although it's not detected. In such a
1415 case, use force_ac97=1 option - but *NO* guarantee whether it
1418 Note: The NM256 chip can be linked internally with non-AC97
1419 codecs. This driver supports only the AC97 codec, and won't work
1420 with machines with other (most likely CS423x or OPL3SAx) chips,
1421 even though the device is detected in lspci. In such a case, try
1422 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1423 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1424 and proper hardware parameters in the case without ISA PnP.
1426 Note: some laptops need a workaround for AC97 RESET. For the
1427 known hardware like Dell Latitude LS and Sony PCG-F305, this
1428 workaround is enabled automatically. For other laptops with a
1429 hard freeze, you can try reset_workaround=1 option.
1431 Note: Dell Latitude CSx laptops have another problem regarding
1432 AC97 RESET. On these laptops, reset_workaround2 option is
1433 turned on as default. This option is worth to try if the
1434 previous reset_workaround option doesn't help.
1436 Note: This driver is really crappy. It's a porting from the
1437 OSS driver, which is a result of black-magic reverse engineering.
1438 The detection of codec will fail if the driver is loaded *after*
1439 X-server as described above. You might be able to force to load
1440 the module, but it may result in hang-up. Hence, make sure that
1441 you load this module *before* X if you encounter this kind of

1726 isapnp - ISA PnP detection - 0 = disable, 1 = enable (default)
1728 The below are options for wavefront_synth features:
1729 wf_raw - Assume that we need to boot the OS (default:no)
1730 If yes, then during driver loading, the state of the board is
1731 ignored, and we reset the board and load the firmware anyway.
1732 fx_raw - Assume that the FX process needs help (default:yes)
1733 If false, we'll leave the FX processor in whatever state it is
1734 when the driver is loaded. The default is to download the
1735 microprogram and associated coefficients to set it up for
1736 "default" operation, whatever that means.
1737 debug_default - Debug parameters for card initialization
1738 wait_usecs - How long to wait without sleeping, usecs
1740 This magic number seems to give pretty optimal throughput
1741 based on my limited experimentation.
1742 If you want to play around with it and find a better value, be
1743 my guest. Remember, the idea is to get a number that causes us
1744 to just busy wait for as many WaveFront commands as possible,
1745 without coming up with a number so large that we hog the whole
1747 Specifically, with this number, out of about 134,000 status
1748 waits, only about 250 result in a sleep.
1749 sleep_interval - How long to sleep when waiting for reply
1751 sleep_tries - How many times to try sleeping during a wait
1753 ospath - Pathname to processed ICS2115 OS firmware
1754 (default:wavefront.os)
1755 The path name of the ISC2115 OS firmware. In the recent
1756 version, it's handled via firmware loader framework, so it
1757 must be installed in the proper path, typically,
1759 reset_time - How long to wait for a reset to take effect
1761 ramcheck_time - How many seconds to wait for the RAM test
1763 osrun_time - How many seconds to wait for the ICS2115 OS
1766 This module supports multiple cards and ISA PnP.
1768 Note: the firmware file "wavefront.os" was located in the earlier
1769 version in /etc. Now it's loaded via firmware loader, and
1770 must be in the proper firmware path, such as /lib/firmware.
1771 Copy (or symlink) the file appropriately if you get an error
1772 regarding firmware downloading after upgrading the kernel.

1877 See "AC97 Quirk Option" section below.
1879 This module supports one chip and autoprobe.
1881 Note: on some SMP motherboards like MSI 694D the interrupts might
1882 not be generated properly. In such a case, please try to
1883 set the SMP (or MPS) version on BIOS to 1.1 instead of
1884 default value 1.4. Then the interrupt number will be
1885 assigned under 15. You might also upgrade your BIOS.
1887 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1888 channels as the first PCM. On these channels, up to 4
1889 streams can be played at the same time, and the controller
1890 can perform sample rate conversion with separate rates for
1892 As default (dxs_support = 0), 48k fixed rate is chosen
1893 except for the known devices since the output is often
1894 noisy except for 48k on some mother boards due to the
1896 Please try once dxs_support=5 and if it works on other
1897 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1898 know the PCI subsystem vendor/device id's (output of
1900 If dxs_support=5 does not work, try dxs_support=4; if it
1901 doesn't work too, try dxs_support=1. (dxs_support=1 is
1902 usually for old motherboards. The correct implemented
1903 board should work with 4 or 5.) If it still doesn't
1904 work and the default setting is ok, dxs_support=3 is the
1905 right choice. If the default setting doesn't work at all,
1906 try dxs_support=2 to disable the DXS channels.
1907 In any cases, please let us know the result and the
1908 subsystem vendor/device ids. See "Links and Addresses"
1911 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1949 This module supports multiple cards.
1951 When the driver is compiled as a module and the hotplug firmware
1952 is supported, the firmware data is loaded via hotplug automatically.
1953 Install the necessary firmware files in alsa-firmware package.
1954 When no hotplug fw loader is available, you need to load the
1955 firmware via vxloader utility in alsa-tools package. To invoke
1956 vxloader automatically, add the following to /etc/modprobe.conf
1958 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1960 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1961 /etc/modules.conf, instead.)
1962 IBL size defines the interrupts period for PCM. The smaller size
1963 gives smaller latency but leads to more CPU consumption, too.
1964 The size is usually aligned to 126. As default (=0), the smallest
1965 size is chosen. The possible IBL values can be found in
1966 /proc/asound/cardX/vx-status proc file.
1968 The power-management is supported.
1973 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.

1978 PCMCIA is supported on kernel.
1980 With the older 2.6.x kernel, to activate the driver via the card
1981 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1982 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1983 longer require a config file.
1985 When the driver is compiled as a module and the hotplug firmware
1986 is supported, the firmware data is loaded via hotplug automatically.
1987 Install the necessary firmware files in alsa-firmware package.
1988 When no hotplug fw loader is available, you need to load the
1989 firmware via vxloader utility in alsa-tools package.
1991 About capture IBL, see the description of snd-vx222 module.
1993 Note: snd-vxp440 driver is merged to snd-vxpocket driver since

2005 fm_port - 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default
2006 1 (auto-detect for YMF744/754 only)
2007 joystick_port - 0x201,0x202,0x204,0x205, 0 (disable) by default,
2009 rear_switch - enable shared rear/line-in switch (bool)
2011 This module supports autoprobe and multiple chips.
2013 The power-management is supported.
2015 Module snd-pdaudiocf
2016 --------------------
2018 Module for Sound Core PDAudioCF sound card.
2020 The power-management is supported.
2026 The ac97_quirk option is used to enable/override the workaround for
2027 specific devices on drivers for on-board AC'97 controllers like
2028 snd-intel8x0. Some hardware have swapped output pins between Master
2029 and Headphone, or Surround (thanks to confusion of AC'97
2030 specifications from version to version :-)
2032 The driver provides the auto-detection of known problematic devices,
2033 but some might be unknown or wrongly detected. In such a case, pass
2034 the proper value with this option.
2036 The following strings are accepted:
2037 - default Don't override the default setting
2038 - none Disable the quirk
2039 - hp_only Bind Master and Headphone controls as a single control
2040 - swap_hp Swap headphone and master controls
2041 - swap_surround Swap master and surround controls
2042 - ad_sharing For AD1985, turn on OMS bit and use headphone
2043 - alc_jack For ALC65x, turn on the jack sense mode
2044 - inv_eapd Inverted EAPD implementation
2045 - mute_led Bind EAPD bit for turning on/off mute LED
2047 For backward compatibility, the corresponding integer value -1, 0,
2048 ... are accepted, too.
2050 For example, if "Master" volume control has no effect on your device
2051 but only "Headphone" does, pass ac97_quirk=hp_only module option.
2054 Configuring Non-ISAPNP Cards
2055 ============================
2057 When the kernel is configured with ISA-PnP support, the modules
2058 supporting the isapnp cards will have module options "isapnp".
2059 If this option is set, *only* the ISA-PnP devices will be probed.
2060 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
2061 together with the proper i/o and irq configuration.
2063 When the kernel is configured without ISA-PnP support, isapnp option
2064 will be not built in.
2067 Module Autoloading Support
2068 ==========================
2070 The ALSA drivers can be loaded automatically on demand by defining
2071 module aliases. The string 'snd-card-%1' is requested for ALSA native
2072 devices where %i is sound card number from zero to seven.
2074 To auto-load an ALSA driver for OSS services, define the string
2075 'sound-slot-%i' where %i means the slot number for OSS, which
2076 corresponds to the card index of ALSA. Usually, define this
2077 as the same card module.
2079 An example configuration for a single emu10k1 card is like below:
2080 ----- /etc/modprobe.conf
2081 alias snd-card-0 snd-emu10k1
2082 alias sound-slot-0 snd-emu10k1
2083 ----- /etc/modprobe.conf
2085 The available number of auto-loaded sound cards depends on the module
2086 option "cards_limit" of snd module. As default it's set to 1.
2087 To enable the auto-loading of multiple cards, specify the number of
2088 sound cards in that option.
2090 When multiple cards are available, it'd better to specify the index
2091 number for each card via module option, too, so that the order of
2092 cards is kept consistent.
2094 An example configuration for two sound cards is like below:
2096 ----- /etc/modprobe.conf
2098 options snd cards_limit=2
2099 alias snd-card-0 snd-interwave
2100 alias snd-card-1 snd-ens1371
2101 options snd-interwave index=0
2102 options snd-ens1371 index=1
2104 alias sound-slot-0 snd-interwave
2105 alias sound-slot-1 snd-ens1371
2106 ----- /etc/modprobe.conf
2108 In this example, the interwave card is always loaded as the first card
2109 (index 0) and ens1371 as the second (index 1).
2111 Alternative (and new) way to fixate the slot assignment is to use
2112 "slots" option of snd module. In the case above, specify like the
2115 options snd slots=snd-interwave,snd-ens1371
2117 Then, the first slot (#0) is reserved for snd-interwave driver, and
2118 the second (#1) for snd-ens1371. You can omit index option in each
2119 driver if slots option is used (although you can still have them at
2120 the same time as long as they don't conflict).
2122 The slots option is especially useful for avoiding the possible
2123 hot-plugging and the resultant slot conflict. For example, in the
2124 case above again, the first two slots are already reserved. If any
2125 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
2126 snd-ens1371, it will be assigned to the third or later slot.
2129 ALSA PCM devices to OSS devices mapping
2130 =======================================
2132 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2133 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2134 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2135 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2136 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2137 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2138 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2139 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2140 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2142 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2143 sound card number and second means device number. The ALSA devices
2144 have either 'c' or 'p' suffix indicating the direction, capture and
2145 playback, respectively.
2147 Please note that the device mapping above may be varied via the module
2148 options of snd-pcm-oss module.
2151 Proc interfaces (/proc/asound)
2152 ==============================
2154 /proc/asound/card#/pcm#[cp]/oss
2155 -------------------------------
2156 String "erase" - erase all additional informations about OSS applications
2157 String "<app_name> <fragments> <fragment_size> [<options>]"
2159 <app_name> - name of application with (higher priority) or without path
2160 <fragments> - number of fragments or zero if auto
2161 <fragment_size> - size of fragment in bytes or zero if auto
2162 <options> - optional parameters
2163 - disable the application tries to open a pcm device for
2164 this channel but does not want to use it.
2165 (Cause a bug or mmap needs)
2166 It's good for Quake etc...
2167 - direct don't use plugins
2168 - block force block mode (rvplayer)
2169 - non-block force non-block mode
2170 - whole-frag write only whole fragments (optimization affecting
2172 - no-silence do not fill silence ahead to avoid clicks
2173 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2174 instead of filled blocks
2176 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2177 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2178 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2181 Early Buffer Allocation
2182 =======================
2184 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2185 sometimes it's too late to find such spaces when the driver module is
2186 actually loaded due to memory fragmentation. You can pre-allocate the
2187 PCM buffers by loading snd-page-alloc module and write commands to its
2188 proc file in prior, for example, in the early boot stage like
2189 /etc/init.d/*.local scripts.
2191 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2192 usage of page allocation. In writing, you can send the following
2193 commands to the snd-page-alloc driver:
2195 - add VENDOR DEVICE MASK SIZE BUFFERS
2197 VENDOR and DEVICE are PCI vendor and device IDs. They take
2198 integer numbers (0x prefix is needed for the hex).
2199 MASK is the PCI DMA mask. Pass 0 if not restricted.
2200 SIZE is the size of each buffer to allocate. You can pass
2201 k and m suffix for KB and MB. The max number is 16MB.
2202 BUFFERS is the number of buffers to allocate. It must be greater
2203 than 0. The max number is 4.
2207 This will erase the all pre-allocated buffers which are not in
