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

755 RV630, RV635, RV670, RV770,
759 [Multiple options for each card instance]
760 model - force the model name
761 position_fix - Fix DMA pointer (0 = auto, 1 = use LPIB, 2 = POSBUF)
762 probe_mask - Bitmask to probe codecs (default = -1, meaning all slots)
763 When the bit 8 (0x100) is set, the lower 8 bits are used
764 as the "fixed" codec slots; i.e. the driver probes the
765 slots regardless what hardware reports back
766 probe_only - Only probing and no codec initialization (default=off);
767 Useful to check the initial codec status for debugging
768 bdl_pos_adj - Specifies the DMA IRQ timing delay in samples.
769 Passing -1 will make the driver to choose the appropriate
770 value based on the controller chip.
771 patch - Specifies the early "patch" files to modify the HD-audio
772 setup before initializing the codecs. This option is
773 available only when CONFIG_SND_HDA_PATCH_LOADER=y is set.
774 See HD-Audio.txt for details.
776 [Single (global) options]
777 single_cmd - Use single immediate commands to communicate with
778 codecs (for debugging only)
779 enable_msi - Enable Message Signaled Interrupt (MSI) (default = off)
780 power_save - Automatic power-saving timeout (in second, 0 =
782 power_save_controller - Reset HD-audio controller in power-saving mode
785 This module supports multiple cards and autoprobe.
787 See Documentation/sound/alsa/HD-Audio.txt for more details about
790 Each codec may have a model table for different configurations.
791 If your machine isn't listed there, the default (usually minimal)
792 configuration is set up. You can pass "model=<name>" option to
793 specify a certain model in such a case. There are different
794 models depending on the codec chip. The list of available models
795 is found in HD-Audio-Models.txt
797 The model name "genric" is treated as a special case. When this
798 model is given, the driver uses the generic codec parser without
799 "codec-patch". It's sometimes good for testing and debugging.
801 If the default configuration doesn't work and one of the above
802 matches with your device, report it together with alsa-info.sh
803 output (with --no-upload option) to kernel bugzilla or alsa-devel
804 ML (see the section "Links and Addresses").
806 power_save and power_save_controller options are for power-saving
807 mode. See powersave.txt for details.
809 Note 2: If you get click noises on output, try the module option
810 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
811 register value without FIFO size correction as the current
812 DMA pointer. position_fix=2 will make the driver to use
813 the position buffer instead of reading SD_LPIB register.
814 (Usually SD_LPIB register is more accurate than the
817 NB: If you get many "azx_get_response timeout" messages at
818 loading, it's likely a problem of interrupts (e.g. ACPI irq
819 routing). Try to boot with options like "pci=noacpi". Also, you
820 can try "single_cmd=1" module option. This will switch the
821 communication method between HDA controller and codecs to the
822 single immediate commands instead of CORB/RIRB. Basically, the
823 single command mode is provided only for BIOS, and you won't get
824 unsolicited events, too. But, at least, this works independently
825 from the irq. Remember this is a last resort, and should be
826 avoided as much as possible...
828 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
829 On some hardwares, you may need to add a proper probe_mask option
830 to avoid the "azx_get_response timeout" problem above, instead.
831 This occurs when the access to non-existing or non-working codec slot
832 (likely a modem one) causes a stall of the communication via HD-audio
833 bus. You can see which codec slots are probed by enabling
834 CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec
835 proc files. Then limit the slots to probe by probe_mask option.
836 For example, probe_mask=1 means to probe only the first slot, and
837 probe_mask=4 means only the third slot.
839 The power-management is supported.
844 Module for RME Hammerfall DSP audio interface(s)
846 This module supports multiple cards.

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

1285 reset_workaround - enable AC97 RESET workaround for some laptops
1286 reset_workaround2 - enable extended AC97 RESET workaround for some
1289 This module supports one chip and autoprobe.
1291 The power-management is supported.
1293 Note: on some notebooks the buffer address cannot be detected
1294 automatically, or causes hang-up during initialization.
1295 In such a case, specify the buffer top address explicitly via
1296 the buffer_top option.

1299 Sony F270: buffer_top=0x272800
1300 The driver supports only ac97 codec. It's possible to force
1301 to initialize/use ac97 although it's not detected. In such a
1302 case, use force_ac97=1 option - but *NO* guarantee whether it
1305 Note: The NM256 chip can be linked internally with non-AC97
1306 codecs. This driver supports only the AC97 codec, and won't work
1307 with machines with other (most likely CS423x or OPL3SAx) chips,
1308 even though the device is detected in lspci. In such a case, try
1309 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
1310 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1311 and proper hardware parameters in the case without ISA PnP.
1313 Note: some laptops need a workaround for AC97 RESET. For the
1314 known hardware like Dell Latitude LS and Sony PCG-F305, this
1315 workaround is enabled automatically. For other laptops with a
1316 hard freeze, you can try reset_workaround=1 option.
1318 Note: Dell Latitude CSx laptops have another problem regarding
1319 AC97 RESET. On these laptops, reset_workaround2 option is
1320 turned on as default. This option is worth to try if the
1321 previous reset_workaround option doesn't help.
1323 Note: This driver is really crappy. It's a porting from the
1324 OSS driver, which is a result of black-magic reverse engineering.
1325 The detection of codec will fail if the driver is loaded *after*
1326 X-server as described above. You might be able to force to load
1327 the module, but it may result in hang-up. Hence, make sure that
1328 you load this module *before* X if you encounter this kind of

1663 The below are options for wavefront_synth features:
1664 wf_raw - Assume that we need to boot the OS (default:no)
1665 If yes, then during driver loading, the state of the board is
1666 ignored, and we reset the board and load the firmware anyway.
1667 fx_raw - Assume that the FX process needs help (default:yes)
1668 If false, we'll leave the FX processor in whatever state it is
1669 when the driver is loaded. The default is to download the
1670 microprogram and associated coefficients to set it up for
1671 "default" operation, whatever that means.
1672 debug_default - Debug parameters for card initialization
1673 wait_usecs - How long to wait without sleeping, usecs
1675 This magic number seems to give pretty optimal throughput
1676 based on my limited experimentation.
1677 If you want to play around with it and find a better value, be
1678 my guest. Remember, the idea is to get a number that causes us
1679 to just busy wait for as many WaveFront commands as possible,
1680 without coming up with a number so large that we hog the whole
1682 Specifically, with this number, out of about 134,000 status
1683 waits, only about 250 result in a sleep.
1684 sleep_interval - How long to sleep when waiting for reply
1686 sleep_tries - How many times to try sleeping during a wait
1688 ospath - Pathname to processed ICS2115 OS firmware
1689 (default:wavefront.os)
1690 The path name of the ISC2115 OS firmware. In the recent
1691 version, it's handled via firmware loader framework, so it
1692 must be installed in the proper path, typically,
1694 reset_time - How long to wait for a reset to take effect
1696 ramcheck_time - How many seconds to wait for the RAM test
1698 osrun_time - How many seconds to wait for the ICS2115 OS
1701 This module supports multiple cards and ISA PnP.
1703 Note: the firmware file "wavefront.os" was located in the earlier
1704 version in /etc. Now it's loaded via firmware loader, and
1705 must be in the proper firmware path, such as /lib/firmware.
1706 Copy (or symlink) the file appropriately if you get an error
1707 regarding firmware downloading after upgrading the kernel.

1778 This module supports multiple devices, autoprobe and hotplugging.
1780 NB: nrpacks parameter can be modified dynamically via sysfs.
1781 Don't put the value over 20. Changing via sysfs has no sanity
1783 NB: async_unlink=0 would cause Oops. It remains just for
1784 debugging purpose (if any).
1785 NB: ignore_ctl_error=1 may help when you get an error at accessing
1786 the mixer element such as URB error -22. This happens on some
1787 buggy USB device or the controller.

1829 This module supports one chip and autoprobe.
1831 Note: on some SMP motherboards like MSI 694D the interrupts might
1832 not be generated properly. In such a case, please try to
1833 set the SMP (or MPS) version on BIOS to 1.1 instead of
1834 default value 1.4. Then the interrupt number will be
1835 assigned under 15. You might also upgrade your BIOS.
1837 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1838 channels as the first PCM. On these channels, up to 4
1839 streams can be played at the same time, and the controller
1840 can perform sample rate conversion with separate rates for
1842 As default (dxs_support = 0), 48k fixed rate is chosen
1843 except for the known devices since the output is often
1844 noisy except for 48k on some mother boards due to the
1846 Please try once dxs_support=5 and if it works on other
1847 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1848 know the PCI subsystem vendor/device id's (output of
1850 If dxs_support=5 does not work, try dxs_support=4; if it
1851 doesn't work too, try dxs_support=1. (dxs_support=1 is
1852 usually for old motherboards. The correct implemented
1853 board should work with 4 or 5.) If it still doesn't
1854 work and the default setting is ok, dxs_support=3 is the
1855 right choice. If the default setting doesn't work at all,
1856 try dxs_support=2 to disable the DXS channels.
1857 In any cases, please let us know the result and the
1858 subsystem vendor/device ids. See "Links and Addresses"
1861 Note: for the MPU401 on VIA823x, use snd-mpu401 driver

1910 When the driver is compiled as a module and the hotplug firmware
1911 is supported, the firmware data is loaded via hotplug automatically.
1912 Install the necessary firmware files in alsa-firmware package.
1913 When no hotplug fw loader is available, you need to load the
1914 firmware via vxloader utility in alsa-tools package. To invoke
1915 vxloader automatically, add the following to /etc/modprobe.conf
1917 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1919 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1920 /etc/modules.conf, instead.)
1921 IBL size defines the interrupts period for PCM. The smaller size
1922 gives smaller latency but leads to more CPU consumption, too.
1923 The size is usually aligned to 126. As default (=0), the smallest
1924 size is chosen. The possible IBL values can be found in
1925 /proc/asound/cardX/vx-status proc file.
1927 The power-management is supported.
1932 Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards.

1937 PCMCIA is supported on kernel.
1939 With the older 2.6.x kernel, to activate the driver via the card
1940 manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the
1941 sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no
1942 longer require a config file.
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.
1950 About capture IBL, see the description of snd-vx222 module.

1985 The ac97_quirk option is used to enable/override the workaround for
1986 specific devices on drivers for on-board AC'97 controllers like
1987 snd-intel8x0. Some hardware have swapped output pins between Master
1988 and Headphone, or Surround (thanks to confusion of AC'97
1989 specifications from version to version :-)
1991 The driver provides the auto-detection of known problematic devices,
1992 but some might be unknown or wrongly detected. In such a case, pass
1993 the proper value with this option.
1995 The following strings are accepted:
1996 - default Don't override the default setting
1997 - none Disable the quirk
1998 - hp_only Bind Master and Headphone controls as a single control
1999 - swap_hp Swap headphone and master controls
2000 - swap_surround Swap master and surround controls
2001 - ad_sharing For AD1985, turn on OMS bit and use headphone
2002 - alc_jack For ALC65x, turn on the jack sense mode
2003 - inv_eapd Inverted EAPD implementation
2004 - mute_led Bind EAPD bit for turning on/off mute LED
2006 For backward compatibility, the corresponding integer value -1, 0,
2007 ... are accepted, too.
2009 For example, if "Master" volume control has no effect on your device
2010 but only "Headphone" does, pass ac97_quirk=hp_only module option.
2013 Configuring Non-ISAPNP Cards
2014 ============================
2016 When the kernel is configured with ISA-PnP support, the modules
2017 supporting the isapnp cards will have module options "isapnp".
2018 If this option is set, *only* the ISA-PnP devices will be probed.
2019 For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
2020 together with the proper i/o and irq configuration.
2022 When the kernel is configured without ISA-PnP support, isapnp option
2023 will be not built in.
2026 Module Autoloading Support
2027 ==========================
2029 The ALSA drivers can be loaded automatically on demand by defining
2030 module aliases. The string 'snd-card-%1' is requested for ALSA native
2031 devices where %i is sound card number from zero to seven.
2033 To auto-load an ALSA driver for OSS services, define the string
2034 'sound-slot-%i' where %i means the slot number for OSS, which
2035 corresponds to the card index of ALSA. Usually, define this
2036 as the same card module.
2038 An example configuration for a single emu10k1 card is like below:
2039 ----- /etc/modprobe.conf
2040 alias snd-card-0 snd-emu10k1
2041 alias sound-slot-0 snd-emu10k1
2042 ----- /etc/modprobe.conf
2044 The available number of auto-loaded sound cards depends on the module
2045 option "cards_limit" of snd module. As default it's set to 1.
2046 To enable the auto-loading of multiple cards, specify the number of
2047 sound cards in that option.
2049 When multiple cards are available, it'd better to specify the index
2050 number for each card via module option, too, so that the order of
2051 cards is kept consistent.
2053 An example configuration for two sound cards is like below:
2055 ----- /etc/modprobe.conf
2057 options snd cards_limit=2
2058 alias snd-card-0 snd-interwave
2059 alias snd-card-1 snd-ens1371
2060 options snd-interwave index=0
2061 options snd-ens1371 index=1
2063 alias sound-slot-0 snd-interwave
2064 alias sound-slot-1 snd-ens1371
2065 ----- /etc/modprobe.conf
2067 In this example, the interwave card is always loaded as the first card
2068 (index 0) and ens1371 as the second (index 1).
2070 Alternative (and new) way to fixate the slot assignment is to use
2071 "slots" option of snd module. In the case above, specify like the
2074 options snd slots=snd-interwave,snd-ens1371
2076 Then, the first slot (#0) is reserved for snd-interwave driver, and
2077 the second (#1) for snd-ens1371. You can omit index option in each
2078 driver if slots option is used (although you can still have them at
2079 the same time as long as they don't conflict).
2081 The slots option is especially useful for avoiding the possible
2082 hot-plugging and the resultant slot conflict. For example, in the
2083 case above again, the first two slots are already reserved. If any
2084 other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
2085 snd-ens1371, it will be assigned to the third or later slot.
2087 When a module name is given with '!', the slot will be given for any
2088 modules but that name. For example, "slots=!snd-pcsp" will reserve
2089 the first slot for any modules but snd-pcsp.
2092 ALSA PCM devices to OSS devices mapping
2093 =======================================
2095 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2096 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2097 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2098 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2099 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2100 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2101 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2102 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2103 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2105 The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2106 sound card number and second means device number. The ALSA devices
2107 have either 'c' or 'p' suffix indicating the direction, capture and
2108 playback, respectively.
2110 Please note that the device mapping above may be varied via the module
2111 options of snd-pcm-oss module.
2114 Proc interfaces (/proc/asound)
2115 ==============================
2117 /proc/asound/card#/pcm#[cp]/oss
2118 -------------------------------
2119 String "erase" - erase all additional informations about OSS applications
2120 String "<app_name> <fragments> <fragment_size> [<options>]"
2122 <app_name> - name of application with (higher priority) or without path
2123 <fragments> - number of fragments or zero if auto
2124 <fragment_size> - size of fragment in bytes or zero if auto
2125 <options> - optional parameters
2126 - disable the application tries to open a pcm device for
2127 this channel but does not want to use it.
2128 (Cause a bug or mmap needs)
2129 It's good for Quake etc...
2130 - direct don't use plugins
2131 - block force block mode (rvplayer)
2132 - non-block force non-block mode
2133 - whole-frag write only whole fragments (optimization affecting
2135 - no-silence do not fill silence ahead to avoid clicks
2136 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
2137 instead of filled blocks
2139 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
2140 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
2141 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss
2144 Early Buffer Allocation
2145 =======================
2147 Some drivers (e.g. hdsp) require the large contiguous buffers, and
2148 sometimes it's too late to find such spaces when the driver module is
2149 actually loaded due to memory fragmentation. You can pre-allocate the
2150 PCM buffers by loading snd-page-alloc module and write commands to its
2151 proc file in prior, for example, in the early boot stage like
2152 /etc/init.d/*.local scripts.
2154 Reading the proc file /proc/drivers/snd-page-alloc shows the current
2155 usage of page allocation. In writing, you can send the following
2156 commands to the snd-page-alloc driver:
2158 - add VENDOR DEVICE MASK SIZE BUFFERS
2160 VENDOR and DEVICE are PCI vendor and device IDs. They take
2161 integer numbers (0x prefix is needed for the hex).
2162 MASK is the PCI DMA mask. Pass 0 if not restricted.
2163 SIZE is the size of each buffer to allocate. You can pass
2164 k and m suffix for KB and MB. The max number is 16MB.
2165 BUFFERS is the number of buffers to allocate. It must be greater
2166 than 0. The max number is 4.
2170 This will erase the all pre-allocated buffers which are not in
