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.
60 device_mode
61 - permission mask for dynamic sound device filesystem
62 - This is available only when DEVFS is enabled
63 - Default: 0666
64 - E.g.: device_mode=0660
65
66
67 Module snd-pcm-oss
68 ------------------
69
70 The PCM OSS emulation module.
71 This module takes options which change the mapping of devices.
72
73 dsp_map - PCM device number maps assigned to the 1st OSS device.
74 - Default: 0
75 adsp_map - PCM device number maps assigned to the 2st OSS device.
76 - Default: 1
77 nonblock_open
Takashi Iwai62430082005-09-05 17:12:29 +020078 - Don't block opening busy PCM devices. Default: 1
Linus Torvalds1da177e2005-04-16 15:20:36 -070079
80 For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of
81 the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped
82 to PCM #0 of the card #0.
83 For changing the second or later card, specify the option with
84 commas, such like "dsp_map=0,1".
85
86 nonblock_open option is used to change the behavior of the PCM
87 regarding opening the device. When this option is non-zero,
88 opening a busy OSS PCM device won't be blocked but return
89 immediately with EAGAIN (just like O_NONBLOCK flag).
90
91 Module snd-rawmidi
92 ------------------
93
94 This module takes options which change the mapping of devices.
95 similar to those of the snd-pcm-oss module.
96
97 midi_map - MIDI device number maps assigned to the 1st OSS device.
98 - Default: 0
99 amidi_map - MIDI device number maps assigned to the 2st OSS device.
100 - Default: 1
101
102 Common parameters for top sound card modules
103 --------------------------------------------
104
105 Each of top level sound card module takes the following options.
106
107 index - index (slot #) of sound card
Clemens Ladisch0ef797c2005-11-21 07:30:20 +0100108 - Values: 0 through 31 or negative
Linus Torvalds1da177e2005-04-16 15:20:36 -0700109 - If nonnegative, assign that index number
110 - if negative, interpret as a bitmask of permissible
111 indices; the first free permitted index is assigned
112 - Default: -1
113 id - card ID (identifier or name)
114 - Can be up to 15 characters long
115 - Default: the card type
116 - A directory by this name is created under /proc/asound/
117 containing information about the card
118 - This ID can be used instead of the index number in
119 identifying the card
120 enable - enable card
121 - Default: enabled, for PCI and ISA PnP cards

Takashi Iwai62430082005-09-05 17:12:29 +0200763 If the default configuration doesn't work and one of the above
764 matches with your device, report it together with the PCI
765 subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
766 ML (see the section "Links and Addresses").
767
Takashi Iwaic74db862005-05-12 14:26:27 +0200768 Note 2: If you get click noises on output, try the module option
769 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
770 register value without FIFO size correction as the current
771 DMA pointer. position_fix=2 will make the driver to use
772 the position buffer instead of reading SD_LPIB register.
773 (Usually SD_LPLIB register is more accurate than the
774 position buffer.)
775
Takashi Iwai27346162006-01-12 18:28:44 +0100776 NB: If you get many "azx_get_response timeout" messages at
777 loading, it's likely a problem of interrupts (e.g. ACPI irq
778 routing). Try to boot with options like "pci=noacpi". Also, you
779 can try "single_cmd=1" module option. This will switch the
780 communication method between HDA controller and codecs to the
781 single immediate commands instead of CORB/RIRB. Basically, the
782 single command mode is provided only for BIOS, and you won't get
783 unsolicited events, too. But, at least, this works independently
784 from the irq. Remember this is a last resort, and should be
785 avoided as much as possible...

1072 The power-management is supported.
1073
1074 Note: on some notebooks the buffer address cannot be detected
1075 automatically, or causes hang-up during initialization.
1076 In such a case, specify the buffer top address explicity via
1077 buffer_top option.
1078 For example,
1079 Sony F250: buffer_top=0x25a800
1080 Sony F270: buffer_top=0x272800
1081 The driver supports only ac97 codec. It's possible to force
1082 to initialize/use ac97 although it's not detected. In such a
1083 case, use force_ac97=1 option - but *NO* guarantee whether it
1084 works!
1085
1086 Note: The NM256 chip can be linked internally with non-AC97
1087 codecs. This driver supports only the AC97 codec, and won't work
1088 with machines with other (most likely CS423x or OPL3SAx) chips,
1089 even though the device is detected in lspci. In such a case, try
1090 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
Takashi Iwai62430082005-09-05 17:12:29 +02001091 but some doesn't have ISA PnP. You'll need to specify isapnp=0
Linus Torvalds1da177e2005-04-16 15:20:36 -07001092 and proper hardware parameters in the case without ISA PnP.
1093
1094 Note: some laptops need a workaround for AC97 RESET. For the
1095 known hardware like Dell Latitude LS and Sony PCG-F305, this
1096 workaround is enabled automatically. For other laptops with a
1097 hard freeze, you can try reset_workaround=1 option.

Takashi Iwaid1f38cf2005-10-19 16:04:27 +02001099 Note: Dell Latitude CSx laptops have another problem regarding
1100 AC97 RESET. On these laptops, reset_workaround2 option is
1101 turned on as default. This option is worth to try if the
1102 previous reset_workaround option doesn't help.

Linus Torvalds1da177e2005-04-16 15:20:36 -07001104 Note: This driver is really crappy. It's a porting from the
1105 OSS driver, which is a result of black-magic reverse engineering.
1106 The detection of codec will fail if the driver is loaded *after*
1107 X-server as described above. You might be able to force to load
1108 the module, but it may result in hang-up. Hence, make sure that
1109 you load this module *before* X if you encounter this kind of
1110 problem.

Linus Torvalds1da177e2005-04-16 15:20:36 -07001463 channels as the first PCM. On these channels, up to 4
Sergey Vlasov2d7eb7c2005-04-11 15:04:33 +02001464 streams can be played at the same time, and the controller

1466 each channel.
Linus Torvalds1da177e2005-04-16 15:20:36 -07001467 As default (dxs_support = 0), 48k fixed rate is chosen
1468 except for the known devices since the output is often
1469 noisy except for 48k on some mother boards due to the

1603=================
1604
1605The ac97_quirk option is used to enable/override the workaround for
1606specific devices on drivers for on-board AC'97 controllers like
1607snd-intel8x0. Some hardware have swapped output pins between Master
1608and Headphone, or Surround (thanks to confusion of AC'97
1609specifications from version to version :-)
1610
1611The driver provides the auto-detection of known problematic devices,
1612but some might be unknown or wrongly detected. In such a case, pass
1613the proper value with this option.
1614
1615The following strings are accepted:
1616 - default Don't override the default setting
Takashi Iwai10e4097f2005-11-17 11:04:55 +01001617 - none Disable the quirk
Takashi Iwai62430082005-09-05 17:12:29 +02001618 - hp_only Bind Master and Headphone controls as a single control
1619 - swap_hp Swap headphone and master controls
1620 - swap_surround Swap master and surround controls
1621 - ad_sharing For AD1985, turn on OMS bit and use headphone
1622 - alc_jack For ALC65x, turn on the jack sense mode
1623 - inv_eapd Inverted EAPD implementation
1624 - mute_led Bind EAPD bit for turning on/off mute LED
1625
1626For backward compatibility, the corresponding integer value -1, 0,
1627... are accepted, too.
1628
1629For example, if "Master" volume control has no effect on your device
1630but only "Headphone" does, pass ac97_quirk=hp_only module option.
1631
1632
Linus Torvalds1da177e2005-04-16 15:20:36 -07001633Configuring Non-ISAPNP Cards
1634============================
1635
1636When the kernel is configured with ISA-PnP support, the modules
1637supporting the isapnp cards will have module options "isapnp".
1638If this option is set, *only* the ISA-PnP devices will be probed.
1639For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
1640together with the proper i/o and irq configuration.
1641
1642When the kernel is configured without ISA-PnP support, isapnp option
1643will be not built in.
1644
1645
1646Module Autoloading Support
1647==========================
1648
1649The ALSA drivers can be loaded automatically on demand by defining
1650module aliases. The string 'snd-card-%1' is requested for ALSA native
1651devices where %i is sound card number from zero to seven.
1652
1653To auto-load an ALSA driver for OSS services, define the string
1654'sound-slot-%i' where %i means the slot number for OSS, which
1655corresponds to the card index of ALSA. Usually, define this
Tobias Klauserd533f672005-09-10 00:26:46 -07001656as the same card module.
Linus Torvalds1da177e2005-04-16 15:20:36 -07001657
1658An example configuration for a single emu10k1 card is like below:
1659----- /etc/modprobe.conf
1660alias snd-card-0 snd-emu10k1
1661alias sound-slot-0 snd-emu10k1
1662----- /etc/modprobe.conf
1663
1664The available number of auto-loaded sound cards depends on the module
1665option "cards_limit" of snd module. As default it's set to 1.
1666To enable the auto-loading of multiple cards, specify the number of
1667sound cards in that option.
1668
1669When multiple cards are available, it'd better to specify the index
1670number for each card via module option, too, so that the order of
1671cards is kept consistent.
1672
1673An example configuration for two sound cards is like below:
1674
1675----- /etc/modprobe.conf
1676# ALSA portion
1677options snd cards_limit=2
1678alias snd-card-0 snd-interwave
1679alias snd-card-1 snd-ens1371
1680options snd-interwave index=0
1681options snd-ens1371 index=1
1682# OSS/Free portion
1683alias sound-slot-0 snd-interwave
1684alias sound-slot-1 snd-ens1371
1685----- /etc/moprobe.conf
1686
1687In this example, the interwave card is always loaded as the first card
1688(index 0) and ens1371 as the second (index 1).
1689
1690
1691ALSA PCM devices to OSS devices mapping
1692=======================================
1693
1694/dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
1695/dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
1696/dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
1697/dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
1698/dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
1699/dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
1700/dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
1701/dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
1702/dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
1703
1704The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
1705sound card number and second means device number. The ALSA devices
1706have either 'c' or 'p' suffix indicating the direction, capture and
1707playback, respectively.
1708
1709Please note that the device mapping above may be varied via the module
1710options of snd-pcm-oss module.
1711
1712
1713DEVFS support
1714=============
1715
1716The ALSA driver fully supports the devfs extension.
1717You should add lines below to your devfsd.conf file:
1718
1719LOOKUP snd MODLOAD ACTION snd
1720REGISTER ^sound/.* PERMISSIONS root.audio 660
1721REGISTER ^snd/.* PERMISSIONS root.audio 660
1722
1723Warning: These lines assume that you have the audio group in your system.
1724 Otherwise replace audio word with another group name (root for
1725 example).

1737 <fragments> - number of fragments or zero if auto
1738 <fragment_size> - size of fragment in bytes or zero if auto
1739 <options> - optional parameters

1757
Takashi Iwaib6a96912005-05-30 18:27:03 +02001758Early Buffer Allocation
1759=======================
1760
1761Some drivers (e.g. hdsp) require the large contiguous buffers, and
1762sometimes it's too late to find such spaces when the driver module is
1763actually loaded due to memory fragmentation. You can pre-allocate the
1764PCM buffers by loading snd-page-alloc module and write commands to its
1765proc file in prior, for example, in the early boot stage like
1766/etc/init.d/*.local scripts.
1767
1768Reading the proc file /proc/drivers/snd-page-alloc shows the current
1769usage of page allocation. In writing, you can send the following
1770commands to the snd-page-alloc driver:
1771
1772 - add VENDOR DEVICE MASK SIZE BUFFERS
1773
1774 VENDOR and DEVICE are PCI vendor and device IDs. They take
1775 integer numbers (0x prefix is needed for the hex).
1776 MASK is the PCI DMA mask. Pass 0 if not restricted.
1777 SIZE is the size of each buffer to allocate. You can pass
1778 k and m suffix for KB and MB. The max number is 16MB.
1779 BUFFERS is the number of buffers to allocate. It must be greater
1780 than 0. The max number is 4.
1781
1782 - erase
1783
1784 This will erase the all pre-allocated buffers which are not in
1785 use.
