2 Advanced Linux Sound Architecture - Driver
3 ==========================================
4 Configuration guide
5
6
7Kernel Configuration
8====================
9
10To enable ALSA support you need at least to build the kernel with
11primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS,
12you don't have to choose any of the OSS modules.
13
14Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and
15PCM supports if you want to run OSS applications with ALSA.
16
17If you want to support the WaveTable functionality on cards such as
18SB Live! then you need to enable "Sequencer support"
19(CONFIG_SND_SEQUENCER).
20
21To make ALSA debug messages more verbose, enable the "Verbose printk"
22and "Debug" options. To check for memory leaks, turn on "Debug memory"
23too. "Debug detection" will add checks for the detection of cards.
24
25Please 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
27using isapnptools.
28
29
30Creating ALSA devices
31=====================
32
33This depends on your distribution, but normally you use the /dev/MAKEDEV
34script to create the necessary device nodes. On some systems you use a
35script named 'snddevices'.
36
37
38Module parameters
39=================
40
41The user can load modules with options. If the module supports more than
42one card and you have more than one card of the same type then you can
43specify multiple values for the option separated by commas.
44
45Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed.
46
47 Module snd
48 ----------
49
50 The core ALSA module. It is used by all ALSA card drivers.
51 It takes the following options which have global effects.
52
53 major - major number for sound driver
54 - Default: 116
55 cards_limit
56 - limiting card index for auto-loading (1-8)
57 - Default: 1
58 - For auto-loading more than one card, specify this
59 option together with snd-card-X aliases.
Linus Torvalds1da177e2005-04-16 15:20:36 -070060
61
62 Module snd-pcm-oss
63 ------------------
64
65 The PCM OSS emulation module.
66 This module takes options which change the mapping of devices.
67
68 dsp_map - PCM device number maps assigned to the 1st OSS device.
69 - Default: 0
70 adsp_map - PCM device number maps assigned to the 2st OSS device.
71 - Default: 1
72 nonblock_open
Takashi Iwai62430082005-09-05 17:12:29 +020073 - Don't block opening busy PCM devices. Default: 1
Linus Torvalds1da177e2005-04-16 15:20:36 -070074
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".
80
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).
85
86 Module snd-rawmidi
87 ------------------
88
89 This module takes options which change the mapping of devices.
90 similar to those of the snd-pcm-oss module.
91
92 midi_map - MIDI device number maps assigned to the 1st OSS device.
93 - Default: 0
94 amidi_map - MIDI device number maps assigned to the 2st OSS device.
95 - Default: 1
96
97 Common parameters for top sound card modules
98 --------------------------------------------
99
100 Each of top level sound card module takes the following options.
101
102 index - index (slot #) of sound card
Clemens Ladisch0ef797c2005-11-21 07:30:20 +0100103 - Values: 0 through 31 or negative
Linus Torvalds1da177e2005-04-16 15:20:36 -0700104 - If nonnegative, assign that index number
105 - if negative, interpret as a bitmask of permissible
106 indices; the first free permitted index is assigned
107 - Default: -1
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
114 identifying the card
115 enable - enable card
116 - Default: enabled, for PCI and ISA PnP cards
117
Rene Hermancf40a312006-03-28 12:38:20 +0200118 Module snd-adlib
119 ----------------
120
121 Module for AdLib FM cards.
122
123 port - port # for OPL chip
124
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
128 synthesis.
129
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:
133
134 Port Client name Port name
135 64:0 OPL2 FM synth OPL2 FM Port
136
137 Load the std.sb and drums.sb patches also supplied by sbiload:
138
139 sbiload -p 64:0 std.sb drums.sb
140
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:
143
144 aplaymidi -p 64:0 foo.mid

779 Each codec may have a model table for different configurations.
780 If your machine isn't listed there, the default (usually minimal)
781 configuration is set up. You can pass "model=<name>" option to
782 specify a certain model in such a case. There are different
783 models depending on the codec chip.

Takashi Iwai6d7b1d72007-02-26 15:56:46 +01001018 The model name "genric" is treated as a special case. When this
1019 model is given, the driver uses the generic codec parser without
1020 "codec-patch". It's sometimes good for testing and debugging.
1021
Takashi Iwai62430082005-09-05 17:12:29 +02001022 If the default configuration doesn't work and one of the above
1023 matches with your device, report it together with the PCI
1024 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
1025 ML (see the section "Links and Addresses").
1026
Takashi Iwaidee1b662007-08-13 16:10:30 +02001027 When CONFIG_SND_HDA_POWER_SAVE is set, two options, power_save and
1028 power_save_controller become available. power_save specifies the
1029 time to turn off the power automatically at idle status. When
1030 power_save_controller is true, the controller is also turned off.
1031 This might result in more obvious click noise at turning on/off.
1032
Takashi Iwaic74db862005-05-12 14:26:27 +02001033 Note 2: If you get click noises on output, try the module option
1034 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
1035 register value without FIFO size correction as the current
1036 DMA pointer. position_fix=2 will make the driver to use
1037 the position buffer instead of reading SD_LPIB register.
1038 (Usually SD_LPLIB register is more accurate than the
1039 position buffer.)
1040
Takashi Iwai27346162006-01-12 18:28:44 +01001041 NB: If you get many "azx_get_response timeout" messages at
1042 loading, it's likely a problem of interrupts (e.g. ACPI irq
1043 routing). Try to boot with options like "pci=noacpi". Also, you
1044 can try "single_cmd=1" module option. This will switch the
1045 communication method between HDA controller and codecs to the
1046 single immediate commands instead of CORB/RIRB. Basically, the
1047 single command mode is provided only for BIOS, and you won't get
1048 unsolicited events, too. But, at least, this works independently
1049 from the irq. Remember this is a last resort, and should be
1050 avoided as much as possible...

Takashi Iwai95904742007-05-19 17:06:42 +02001052 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
1053 On some hardwares, you may need to add a proper probe_mask option
1054 to avoid the "azx_get_response timeout" problem above, instead.
1055 This occurs when the access to non-existing or non-working codec slot
1056 (likely a modem one) causes a stall of the communication via HD-audio
1057 bus. You can see which codec slots are probed by enabling
1058 CONFIG_SND_DEBUG_DETECT, or simply from the file name of the codec
1059 proc files. Then limit the slots to probe by probe_mask option.
1060 For example, probe_mask=1 means to probe only the first slot, and
1061 probe_mask=4 means only the third slot.

Takashi Iwaid1f38cf2005-10-19 16:04:27 +02001429 reset_workaround2 - enable extended AC97 RESET workaround for some
1430 other laptops
Linus Torvalds1da177e2005-04-16 15:20:36 -07001431
Takashi Iwai8a3fb4d2005-10-20 17:10:49 +02001432 This module supports one chip and autoprobe.
Linus Torvalds1da177e2005-04-16 15:20:36 -07001433
1434 The power-management is supported.
1435
1436 Note: on some notebooks the buffer address cannot be detected
1437 automatically, or causes hang-up during initialization.
Matt LaPlantefff92892006-10-03 22:47:42 +02001438 In such a case, specify the buffer top address explicitly via
1439 the buffer_top option.
Linus Torvalds1da177e2005-04-16 15:20:36 -07001440 For example,
1441 Sony F250: buffer_top=0x25a800
1442 Sony F270: buffer_top=0x272800
1443 The driver supports only ac97 codec. It's possible to force
1444 to initialize/use ac97 although it's not detected. In such a
1445 case, use force_ac97=1 option - but *NO* guarantee whether it
1446 works!
1447
1448 Note: The NM256 chip can be linked internally with non-AC97
1449 codecs. This driver supports only the AC97 codec, and won't work
1450 with machines with other (most likely CS423x or OPL3SAx) chips,
1451 even though the device is detected in lspci. In such a case, try
1452 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
Takashi Iwai62430082005-09-05 17:12:29 +02001453 but some doesn't have ISA PnP. You'll need to specify isapnp=0
Linus Torvalds1da177e2005-04-16 15:20:36 -07001454 and proper hardware parameters in the case without ISA PnP.
1455
1456 Note: some laptops need a workaround for AC97 RESET. For the
1457 known hardware like Dell Latitude LS and Sony PCG-F305, this
1458 workaround is enabled automatically. For other laptops with a
1459 hard freeze, you can try reset_workaround=1 option.
1460
Takashi Iwaid1f38cf2005-10-19 16:04:27 +02001461 Note: Dell Latitude CSx laptops have another problem regarding
1462 AC97 RESET. On these laptops, reset_workaround2 option is
1463 turned on as default. This option is worth to try if the
1464 previous reset_workaround option doesn't help.
1465
Linus Torvalds1da177e2005-04-16 15:20:36 -07001466 Note: This driver is really crappy. It's a porting from the
1467 OSS driver, which is a result of black-magic reverse engineering.
1468 The detection of codec will fail if the driver is loaded *after*
1469 X-server as described above. You might be able to force to load
1470 the module, but it may result in hang-up. Hence, make sure that
1471 you load this module *before* X if you encounter this kind of
1472 problem.

Takashi Iwaic2b12392007-08-21 15:20:26 +02001758 The below are options for wavefront_synth features:
1759 wf_raw - Assume that we need to boot the OS (default:no)
1760 If yes, then during driver loading, the state of the board is
1761 ignored, and we reset the board and load the firmware anyway.
1762 fx_raw - Assume that the FX process needs help (default:yes)
1763 If false, we'll leave the FX processor in whatever state it is
1764 when the driver is loaded. The default is to download the
1765 microprogram and associated coefficients to set it up for
1766 "default" operation, whatever that means.
1767 debug_default - Debug parameters for card initialization
1768 wait_usecs - How long to wait without sleeping, usecs
1769 (default:150)
1770 This magic number seems to give pretty optimal throughput
1771 based on my limited experimentation.
1772 If you want to play around with it and find a better value, be
1773 my guest. Remember, the idea is to get a number that causes us
1774 to just busy wait for as many WaveFront commands as possible,
1775 without coming up with a number so large that we hog the whole
1776 CPU.
1777 Specifically, with this number, out of about 134,000 status
1778 waits, only about 250 result in a sleep.
1779 sleep_interval - How long to sleep when waiting for reply
1780 (default: 100)
1781 sleep_tries - How many times to try sleeping during a wait
1782 (default: 50)
1783 ospath - Pathname to processed ICS2115 OS firmware
1784 (default:wavefront.os)
1785 The path name of the ISC2115 OS firmware. In the recent
1786 version, it's handled via firmware loader framework, so it
1787 must be installed in the proper path, typically,
1788 /lib/firmware.
1789 reset_time - How long to wait for a reset to take effect
1790 (default:2)
1791 ramcheck_time - How many seconds to wait for the RAM test
1792 (default:20)
1793 osrun_time - How many seconds to wait for the ICS2115 OS
1794 (default:10)

2055
2056The ac97_quirk option is used to enable/override the workaround for
2057specific devices on drivers for on-board AC'97 controllers like
2058snd-intel8x0. Some hardware have swapped output pins between Master
2059and Headphone, or Surround (thanks to confusion of AC'97
2060specifications from version to version :-)
2061
2062The driver provides the auto-detection of known problematic devices,
2063but some might be unknown or wrongly detected. In such a case, pass
2064the proper value with this option.
2065
2066The following strings are accepted:
2067 - default Don't override the default setting
Takashi Iwai10e4097f2005-11-17 11:04:55 +01002068 - none Disable the quirk
Takashi Iwai62430082005-09-05 17:12:29 +02002069 - hp_only Bind Master and Headphone controls as a single control
2070 - swap_hp Swap headphone and master controls
2071 - swap_surround Swap master and surround controls
2072 - ad_sharing For AD1985, turn on OMS bit and use headphone
2073 - alc_jack For ALC65x, turn on the jack sense mode
2074 - inv_eapd Inverted EAPD implementation
2075 - mute_led Bind EAPD bit for turning on/off mute LED
2076
2077For backward compatibility, the corresponding integer value -1, 0,
2078... are accepted, too.
2079
2080For example, if "Master" volume control has no effect on your device
2081but only "Headphone" does, pass ac97_quirk=hp_only module option.

2085============================
2086
2087When the kernel is configured with ISA-PnP support, the modules
2088supporting the isapnp cards will have module options "isapnp".
2089If this option is set, *only* the ISA-PnP devices will be probed.
2090For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
2091together with the proper i/o and irq configuration.
2092
2093When the kernel is configured without ISA-PnP support, isapnp option
2094will be not built in.

2104To auto-load an ALSA driver for OSS services, define the string
2105'sound-slot-%i' where %i means the slot number for OSS, which
2106corresponds to the card index of ALSA. Usually, define this
Tobias Klauserd533f672005-09-10 00:26:46 -07002107as the same card module.

2109An example configuration for a single emu10k1 card is like below:
2110----- /etc/modprobe.conf
2111alias snd-card-0 snd-emu10k1
2112alias sound-slot-0 snd-emu10k1
2113----- /etc/modprobe.conf
2114
2115The available number of auto-loaded sound cards depends on the module
2116option "cards_limit" of snd module. As default it's set to 1.
2117To enable the auto-loading of multiple cards, specify the number of
2118sound cards in that option.
2119
2120When multiple cards are available, it'd better to specify the index
2121number for each card via module option, too, so that the order of
2122cards is kept consistent.
2123
2124An example configuration for two sound cards is like below:
2125
2126----- /etc/modprobe.conf
2127# ALSA portion
2128options snd cards_limit=2
2129alias snd-card-0 snd-interwave
2130alias snd-card-1 snd-ens1371
2131options snd-interwave index=0
2132options snd-ens1371 index=1
2133# OSS/Free portion
2134alias sound-slot-0 snd-interwave
2135alias sound-slot-1 snd-ens1371
Matt LaPlante2fe0ae72006-10-03 22:50:39 +02002136----- /etc/modprobe.conf
Linus Torvalds1da177e2005-04-16 15:20:36 -07002137
2138In this example, the interwave card is always loaded as the first card
2139(index 0) and ens1371 as the second (index 1).

2142ALSA PCM devices to OSS devices mapping
2143=======================================
2144
2145/dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
2146/dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
2147/dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
2148/dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
2149/dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
2150/dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
2151/dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
2152/dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
2153/dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2154
2155The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2156sound card number and second means device number. The ALSA devices
2157have either 'c' or 'p' suffix indicating the direction, capture and
2158playback, respectively.
2159
2160Please note that the device mapping above may be varied via the module
2161options of snd-pcm-oss module.

2165==============================
2166
2167/proc/asound/card#/pcm#[cp]/oss
2168-------------------------------
2169 String "erase" - erase all additional informations about OSS applications
2170 String "<app_name> <fragments> <fragment_size> [<options>]"
2171
2172 <app_name> - name of application with (higher priority) or without path
2173 <fragments> - number of fragments or zero if auto
2174 <fragment_size> - size of fragment in bytes or zero if auto
2175 <options> - optional parameters
2176 - disable the application tries to open a pcm device for
2177 this channel but does not want to use it.
2178 (Cause a bug or mmap needs)
2179 It's good for Quake etc...
2180 - direct don't use plugins
2181 - block force block mode (rvplayer)
2182 - non-block force non-block mode
2183 - whole-frag write only whole fragments (optimization affecting
2184 playback only)
2185 - no-silence do not fill silence ahead to avoid clicks

Takashi Iwaib6a96912005-05-30 18:27:03 +02002194Early Buffer Allocation
2195=======================
2196
2197Some drivers (e.g. hdsp) require the large contiguous buffers, and
2198sometimes it's too late to find such spaces when the driver module is
2199actually loaded due to memory fragmentation. You can pre-allocate the
2200PCM buffers by loading snd-page-alloc module and write commands to its
2201proc file in prior, for example, in the early boot stage like
2202/etc/init.d/*.local scripts.
2203
2204Reading the proc file /proc/drivers/snd-page-alloc shows the current
2205usage of page allocation. In writing, you can send the following
2206commands to the snd-page-alloc driver:
2207
2208 - add VENDOR DEVICE MASK SIZE BUFFERS
2209
2210 VENDOR and DEVICE are PCI vendor and device IDs. They take
2211 integer numbers (0x prefix is needed for the hex).
2212 MASK is the PCI DMA mask. Pass 0 if not restricted.
2213 SIZE is the size of each buffer to allocate. You can pass
2214 k and m suffix for KB and MB. The max number is 16MB.
2215 BUFFERS is the number of buffers to allocate. It must be greater
2216 than 0. The max number is 4.
2217
2218 - erase
2219
2220 This will erase the all pre-allocated buffers which are not in
2221 use.
