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.
304cd07f
TI
60 slots - Reserve the slot index for the given driver.
61 This option takes multiple strings.
62 See "Module Autoloading Support" section for details.
36ce99c1
TI
63 debug - Specifies the debug message level
64 (0 = disable debug prints, 1 = normal debug messages,
65 2 = verbose debug messages)
66 This option appears only when CONFIG_SND_DEBUG=y.
67 This option can be dynamically changed via sysfs
68 /sys/modules/snd/parameters/debug file.
1da177e4
LT
69
70 Module snd-pcm-oss
71 ------------------
72
73 The PCM OSS emulation module.
74 This module takes options which change the mapping of devices.
75
76 dsp_map - PCM device number maps assigned to the 1st OSS device.
77 - Default: 0
78 adsp_map - PCM device number maps assigned to the 2st OSS device.
79 - Default: 1
80 nonblock_open
6243008b 81 - Don't block opening busy PCM devices. Default: 1
1da177e4
LT
82
83 For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of
84 the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped
85 to PCM #0 of the card #0.
86 For changing the second or later card, specify the option with
87 commas, such like "dsp_map=0,1".
88
89 nonblock_open option is used to change the behavior of the PCM
90 regarding opening the device. When this option is non-zero,
91 opening a busy OSS PCM device won't be blocked but return
92 immediately with EAGAIN (just like O_NONBLOCK flag).
93
94 Module snd-rawmidi
95 ------------------
96
97 This module takes options which change the mapping of devices.
98 similar to those of the snd-pcm-oss module.
99
100 midi_map - MIDI device number maps assigned to the 1st OSS device.
101 - Default: 0
102 amidi_map - MIDI device number maps assigned to the 2st OSS device.
103 - Default: 1
104
105 Common parameters for top sound card modules
106 --------------------------------------------
107
108 Each of top level sound card module takes the following options.
109
110 index - index (slot #) of sound card
0ef797c5 111 - Values: 0 through 31 or negative
1da177e4
LT
112 - If nonnegative, assign that index number
113 - if negative, interpret as a bitmask of permissible
114 indices; the first free permitted index is assigned
115 - Default: -1
116 id - card ID (identifier or name)
117 - Can be up to 15 characters long
118 - Default: the card type
119 - A directory by this name is created under /proc/asound/
120 containing information about the card
121 - This ID can be used instead of the index number in
122 identifying the card
123 enable - enable card
124 - Default: enabled, for PCI and ISA PnP cards

126 Module snd-adlib
127 ----------------
128
129 Module for AdLib FM cards.
130
131 port - port # for OPL chip
132
133 This module supports multiple cards. It does not support autoprobe, so
134 the port must be specified. For actual AdLib FM cards it will be 0x388.
135 Note that this card does not have PCM support and no mixer; only FM
136 synthesis.
137
138 Make sure you have "sbiload" from the alsa-tools package available and,
139 after loading the module, find out the assigned ALSA sequencer port
140 number through "sbiload -l". Example output:
141
142 Port Client name Port name
143 64:0 OPL2 FM synth OPL2 FM Port
144
145 Load the std.sb and drums.sb patches also supplied by sbiload:
146
147 sbiload -p 64:0 std.sb drums.sb
148
149 If you use this driver to drive an OPL3, you can use std.o3 and drums.o3
150 instead. To have the card produce sound, use aplaymidi from alsa-utils:
151
152 aplaymidi -p 64:0 foo.mid

902 The model name "genric" is treated as a special case. When this

914 Note 2: If you get click noises on output, try the module option
915 position_fix=1 or 2. position_fix=1 will use the SD_LPIB

917 DMA pointer. position_fix=2 will make the driver to use
918 the position buffer instead of reading SD_LPIB register.

922 NB: If you get many "azx_get_response timeout" messages at

924 routing). Try to boot with options like "pci=noacpi". Also, you
925 can try "single_cmd=1" module option. This will switch the
926 communication method between HDA controller and codecs to the
927 single immediate commands instead of CORB/RIRB. Basically, the
928 single command mode is provided only for BIOS, and you won't get
929 unsolicited events, too. But, at least, this works independently
930 from the irq. Remember this is a last resort, and should be
931 avoided as much as possible...

933 MORE NOTES ON "azx_get_response timeout" PROBLEMS:
934 On some hardwares, you may need to add a proper probe_mask option
935 to avoid the "azx_get_response timeout" problem above, instead.
936 This occurs when the access to non-existing or non-working codec slot
937 (likely a modem one) causes a stall of the communication via HD-audio
938 bus. You can see which codec slots are probed by enabling
62cf872a 939 CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec
95904743
TI
940 proc files. Then limit the slots to probe by probe_mask option.
941 For example, probe_mask=1 means to probe only the first slot, and
942 probe_mask=4 means only the third slot.

1da177e4
LT
1403
1404 The power-management is supported.
1405
1406 Note: on some notebooks the buffer address cannot be detected
1407 automatically, or causes hang-up during initialization.
fff9289b
ML
1408 In such a case, specify the buffer top address explicitly via
1409 the buffer_top option.
1da177e4
LT
1410 For example,
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
1416 works!
1417
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
6243008b 1423 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1da177e4
LT
1424 and proper hardware parameters in the case without ISA PnP.
1425
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.
1430
d1f38cf9
TI
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.
1435
1da177e4
LT
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
1442 problem.

1768 The below are options for wavefront_synth features:
1769 wf_raw - Assume that we need to boot the OS (default:no)
1770 If yes, then during driver loading, the state of the board is
1771 ignored, and we reset the board and load the firmware anyway.
1772 fx_raw - Assume that the FX process needs help (default:yes)
1773 If false, we'll leave the FX processor in whatever state it is
1774 when the driver is loaded. The default is to download the
1775 microprogram and associated coefficients to set it up for
1776 "default" operation, whatever that means.
1777 debug_default - Debug parameters for card initialization
1778 wait_usecs - How long to wait without sleeping, usecs
1779 (default:150)
1780 This magic number seems to give pretty optimal throughput
1781 based on my limited experimentation.
1782 If you want to play around with it and find a better value, be
1783 my guest. Remember, the idea is to get a number that causes us
1784 to just busy wait for as many WaveFront commands as possible,
1785 without coming up with a number so large that we hog the whole
1786 CPU.

2094AC97 Quirk Option
2095=================
2096
2097The ac97_quirk option is used to enable/override the workaround for
2098specific devices on drivers for on-board AC'97 controllers like
2099snd-intel8x0. Some hardware have swapped output pins between Master
2100and Headphone, or Surround (thanks to confusion of AC'97
2101specifications from version to version :-)
2102
2103The driver provides the auto-detection of known problematic devices,
2104but some might be unknown or wrongly detected. In such a case, pass
2105the proper value with this option.
2106
2107The following strings are accepted:
2108 - default Don't override the default setting
10e4097f 2109 - none Disable the quirk
6243008b
TI
2110 - hp_only Bind Master and Headphone controls as a single control
2111 - swap_hp Swap headphone and master controls
2112 - swap_surround Swap master and surround controls
2113 - ad_sharing For AD1985, turn on OMS bit and use headphone
2114 - alc_jack For ALC65x, turn on the jack sense mode
2115 - inv_eapd Inverted EAPD implementation
2116 - mute_led Bind EAPD bit for turning on/off mute LED
2117
2118For backward compatibility, the corresponding integer value -1, 0,
2119... are accepted, too.
2120
2121For example, if "Master" volume control has no effect on your device
2122but only "Headphone" does, pass ac97_quirk=hp_only module option.

2125Configuring Non-ISAPNP Cards
2126============================
2127
2128When the kernel is configured with ISA-PnP support, the modules
2129supporting the isapnp cards will have module options "isapnp".
2130If this option is set, *only* the ISA-PnP devices will be probed.
2131For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
2132together with the proper i/o and irq configuration.
2133
2134When the kernel is configured without ISA-PnP support, isapnp option
2135will be not built in.
2136
2137
2138Module Autoloading Support
2139==========================
2140
2141The ALSA drivers can be loaded automatically on demand by defining
2142module aliases. The string 'snd-card-%1' is requested for ALSA native
2143devices where %i is sound card number from zero to seven.
2144
2145To auto-load an ALSA driver for OSS services, define the string
2146'sound-slot-%i' where %i means the slot number for OSS, which
2147corresponds to the card index of ALSA. Usually, define this
d533f671 2148as the same card module.
1da177e4
LT
2149
2150An example configuration for a single emu10k1 card is like below:
2151----- /etc/modprobe.conf
2152alias snd-card-0 snd-emu10k1
2153alias sound-slot-0 snd-emu10k1
2154----- /etc/modprobe.conf
2155
2156The available number of auto-loaded sound cards depends on the module
2157option "cards_limit" of snd module. As default it's set to 1.
2158To enable the auto-loading of multiple cards, specify the number of
2159sound cards in that option.
2160
2161When multiple cards are available, it'd better to specify the index
2162number for each card via module option, too, so that the order of
2163cards is kept consistent.
2164
2165An example configuration for two sound cards is like below:
2166
2167----- /etc/modprobe.conf
2168# ALSA portion
2169options snd cards_limit=2
2170alias snd-card-0 snd-interwave
2171alias snd-card-1 snd-ens1371
2172options snd-interwave index=0
2173options snd-ens1371 index=1
2174# OSS/Free portion
2175alias sound-slot-0 snd-interwave
2176alias sound-slot-1 snd-ens1371
2fe0ae78 2177----- /etc/modprobe.conf
1da177e4
LT
2178
2179In this example, the interwave card is always loaded as the first card
2180(index 0) and ens1371 as the second (index 1).
2181
304cd07f
TI
2182Alternative (and new) way to fixate the slot assignment is to use
2183"slots" option of snd module. In the case above, specify like the
2184following:
2185
2186options snd slots=snd-interwave,snd-ens1371
2187
2188Then, the first slot (#0) is reserved for snd-interwave driver, and
2189the second (#1) for snd-ens1371. You can omit index option in each
2190driver if slots option is used (although you can still have them at
2191the same time as long as they don't conflict).
2192
2193The slots option is especially useful for avoiding the possible
2194hot-plugging and the resultant slot conflict. For example, in the
2195case above again, the first two slots are already reserved. If any
2196other driver (e.g. snd-usb-audio) is loaded before snd-interwave or
2197snd-ens1371, it will be assigned to the third or later slot.
2198
a93bbaa7
TI
2199When a module name is given with '!', the slot will be given for any
2200modules but that name. For example, "slots=!snd-pcsp" will reserve
2201the first slot for any modules but snd-pcsp.

2215/dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
2216
2217The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
2218sound card number and second means device number. The ALSA devices
2219have either 'c' or 'p' suffix indicating the direction, capture and
2220playback, respectively.
2221
2222Please note that the device mapping above may be varied via the module
2223options of snd-pcm-oss module.

2226Proc interfaces (/proc/asound)
2227==============================
2228
2229/proc/asound/card#/pcm#[cp]/oss
2230-------------------------------
2231 String "erase" - erase all additional informations about OSS applications
2232 String "<app_name> <fragments> <fragment_size> [<options>]"
2233
2234 <app_name> - name of application with (higher priority) or without path
2235 <fragments> - number of fragments or zero if auto
2236 <fragment_size> - size of fragment in bytes or zero if auto
2237 <options> - optional parameters
2238 - disable the application tries to open a pcm device for
2239 this channel but does not want to use it.
2240 (Cause a bug or mmap needs)
2241 It's good for Quake etc...
2242 - direct don't use plugins
2243 - block force block mode (rvplayer)
2244 - non-block force non-block mode
2245 - whole-frag write only whole fragments (optimization affecting
2246 playback only)
2247 - no-silence do not fill silence ahead to avoid clicks

2256Early Buffer Allocation
2257=======================
2258
2259Some drivers (e.g. hdsp) require the large contiguous buffers, and
2260sometimes it's too late to find such spaces when the driver module is
2261actually loaded due to memory fragmentation. You can pre-allocate the
2262PCM buffers by loading snd-page-alloc module and write commands to its
2263proc file in prior, for example, in the early boot stage like
2264/etc/init.d/*.local scripts.
2265
2266Reading the proc file /proc/drivers/snd-page-alloc shows the current
2267usage of page allocation. In writing, you can send the following
2268commands to the snd-page-alloc driver:
2269
2270 - add VENDOR DEVICE MASK SIZE BUFFERS
2271
2272 VENDOR and DEVICE are PCI vendor and device IDs. They take
2273 integer numbers (0x prefix is needed for the hex).
2274 MASK is the PCI DMA mask. Pass 0 if not restricted.
2275 SIZE is the size of each buffer to allocate. You can pass
2276 k and m suffix for KB and MB. The max number is 16MB.
2277 BUFFERS is the number of buffers to allocate. It must be greater
2278 than 0. The max number is 4.
2279
2280 - erase
2281
2282 This will erase the all pre-allocated buffers which are not in
2283 use.
