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
6243008b 78 - Don't block opening busy PCM devices. Default: 1
1da177e4
LT		 79
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
0ef797c5 108 - Values: 0 through 31 or negative
1da177e4
LT		 109 - 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

TI		 720 Note 2: If you get click noises on output, try the module option
721 position_fix=1 or 2. position_fix=1 will use the SD_LPIB
722 register value without FIFO size correction as the current
723 DMA pointer. position_fix=2 will make the driver to use
724 the position buffer instead of reading SD_LPIB register.
725 (Usually SD_LPLIB register is more accurate than the
726 position buffer.)
727
27346166
TI		 728 NB: If you get many "azx_get_response timeout" messages at
729 loading, it's likely a problem of interrupts (e.g. ACPI irq
730 routing). Try to boot with options like "pci=noacpi". Also, you
731 can try "single_cmd=1" module option. This will switch the
732 communication method between HDA controller and codecs to the
733 single immediate commands instead of CORB/RIRB. Basically, the
734 single command mode is provided only for BIOS, and you won't get
735 unsolicited events, too. But, at least, this works independently
736 from the irq. Remember this is a last resort, and should be
737 avoided as much as possible...

1018 reset_workaround - enable AC97 RESET workaround for some laptops
d1f38cf9
TI		 1019 reset_workaround2 - enable extended AC97 RESET workaround for some
1020 other laptops
1da177e4 1021
8a3fb4d0 1022 This module supports one chip and autoprobe.
1da177e4
LT		 1023
1024 The power-management is supported.
1025
1026 Note: on some notebooks the buffer address cannot be detected
1027 automatically, or causes hang-up during initialization.
1028 In such a case, specify the buffer top address explicity via
1029 buffer_top option.
1030 For example,
1031 Sony F250: buffer_top=0x25a800
1032 Sony F270: buffer_top=0x272800
1033 The driver supports only ac97 codec. It's possible to force
1034 to initialize/use ac97 although it's not detected. In such a
1035 case, use force_ac97=1 option - but *NO* guarantee whether it
1036 works!
1037
1038 Note: The NM256 chip can be linked internally with non-AC97
1039 codecs. This driver supports only the AC97 codec, and won't work
1040 with machines with other (most likely CS423x or OPL3SAx) chips,
1041 even though the device is detected in lspci. In such a case, try
1042 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
6243008b 1043 but some doesn't have ISA PnP. You'll need to specify isapnp=0
1da177e4
LT		 1044 and proper hardware parameters in the case without ISA PnP.
1045
1046 Note: some laptops need a workaround for AC97 RESET. For the
1047 known hardware like Dell Latitude LS and Sony PCG-F305, this
1048 workaround is enabled automatically. For other laptops with a
1049 hard freeze, you can try reset_workaround=1 option.
1050
d1f38cf9
TI		 1051 Note: Dell Latitude CSx laptops have another problem regarding
1052 AC97 RESET. On these laptops, reset_workaround2 option is
1053 turned on as default. This option is worth to try if the
1054 previous reset_workaround option doesn't help.
1055
1da177e4
LT		 1056 Note: This driver is really crappy. It's a porting from the
1057 OSS driver, which is a result of black-magic reverse engineering.
1058 The detection of codec will fail if the driver is loaded *after*
1059 X-server as described above. You might be able to force to load
1060 the module, but it may result in hang-up. Hence, make sure that
1061 you load this module *before* X if you encounter this kind of
1062 problem.

1da177e4
LT		 1404
1405 Note: on some SMP motherboards like MSI 694D the interrupts might
1406 not be generated properly. In such a case, please try to
1407 set the SMP (or MPS) version on BIOS to 1.1 instead of
1408 default value 1.4. Then the interrupt number will be
1409 assigned under 15. You might also upgrade your BIOS.
1410
2d7eb7cb 1411 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1da177e4 1412 channels as the first PCM. On these channels, up to 4
2d7eb7cb
SV		 1413 streams can be played at the same time, and the controller
1414 can perform sample rate conversion with separate rates for
1415 each channel.
1da177e4
LT		 1416 As default (dxs_support = 0), 48k fixed rate is chosen
1417 except for the known devices since the output is often
1418 noisy except for 48k on some mother boards due to the
1419 bug of BIOS.
2d7eb7cb 1420 Please try once dxs_support=5 and if it works on other
1da177e4
LT		 1421 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1422 know the PCI subsystem vendor/device id's (output of
1423 "lspci -nv").
cdc27f3a
TI		 1424 If dxs_support=5 does not work, try dxs_support=4; if it
1425 doesn't work too, try dxs_support=1. (dxs_support=1 is
6243008b 1426 usually for old motherboards. The correct implemented
cdc27f3a 1427 board should work with 4 or 5.) If it still doesn't
1da177e4
LT		 1428 work and the default setting is ok, dxs_support=3 is the
1429 right choice. If the default setting doesn't work at all,
1430 try dxs_support=2 to disable the DXS channels.
1431 In any cases, please let us know the result and the
6243008b
TI		 1432 subsystem vendor/device ids. See "Links and Addresses"
1433 below.

1475 When the driver is compiled as a module and the hotplug firmware
1476 is supported, the firmware data is loaded via hotplug automatically.
1477 Install the necessary firmware files in alsa-firmware package.
1478 When no hotplug fw loader is available, you need to load the
1479 firmware via vxloader utility in alsa-tools package. To invoke
1480 vxloader automatically, add the following to /etc/modprobe.conf
1481
1482 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1483
1484 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1485 /etc/modules.conf, instead.)
1486 IBL size defines the interrupts period for PCM. The smaller size
1487 gives smaller latency but leads to more CPU consumption, too.
1488 The size is usually aligned to 126. As default (=0), the smallest
1489 size is chosen. The possible IBL values can be found in
1490 /proc/asound/cardX/vx-status proc file.

TI		 1551AC97 Quirk Option
1552=================
1553
1554The ac97_quirk option is used to enable/override the workaround for
1555specific devices on drivers for on-board AC'97 controllers like
1556snd-intel8x0. Some hardware have swapped output pins between Master
1557and Headphone, or Surround (thanks to confusion of AC'97
1558specifications from version to version :-)
1559
1560The driver provides the auto-detection of known problematic devices,
1561but some might be unknown or wrongly detected. In such a case, pass
1562the proper value with this option.
1563
1564The following strings are accepted:
1565 - default Don't override the default setting
10e4097f 1566 - none Disable the quirk
6243008b
TI		 1567 - hp_only Bind Master and Headphone controls as a single control
1568 - swap_hp Swap headphone and master controls
1569 - swap_surround Swap master and surround controls
1570 - ad_sharing For AD1985, turn on OMS bit and use headphone
1571 - alc_jack For ALC65x, turn on the jack sense mode
1572 - inv_eapd Inverted EAPD implementation
1573 - mute_led Bind EAPD bit for turning on/off mute LED
1574
1575For backward compatibility, the corresponding integer value -1, 0,
1576... are accepted, too.
1577
1578For example, if "Master" volume control has no effect on your device
1579but only "Headphone" does, pass ac97_quirk=hp_only module option.
1580
1581
1da177e4
LT		 1582Configuring Non-ISAPNP Cards
1583============================
1584
1585When the kernel is configured with ISA-PnP support, the modules
1586supporting the isapnp cards will have module options "isapnp".
1587If this option is set, *only* the ISA-PnP devices will be probed.
1588For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
1589together with the proper i/o and irq configuration.
1590
1591When the kernel is configured without ISA-PnP support, isapnp option
1592will be not built in.
1593
1594
1595Module Autoloading Support
1596==========================
1597
1598The ALSA drivers can be loaded automatically on demand by defining
1599module aliases. The string 'snd-card-%1' is requested for ALSA native
1600devices where %i is sound card number from zero to seven.
1601
1602To auto-load an ALSA driver for OSS services, define the string
1603'sound-slot-%i' where %i means the slot number for OSS, which
1604corresponds to the card index of ALSA. Usually, define this
d533f671 1605as the same card module.
1da177e4
LT		 1606
1607An example configuration for a single emu10k1 card is like below:
1608----- /etc/modprobe.conf
1609alias snd-card-0 snd-emu10k1
1610alias sound-slot-0 snd-emu10k1
1611----- /etc/modprobe.conf
1612
1613The available number of auto-loaded sound cards depends on the module
1614option "cards_limit" of snd module. As default it's set to 1.
1615To enable the auto-loading of multiple cards, specify the number of
1616sound cards in that option.
1617
1618When multiple cards are available, it'd better to specify the index
1619number for each card via module option, too, so that the order of
1620cards is kept consistent.
1621
1622An example configuration for two sound cards is like below:
1623
1624----- /etc/modprobe.conf
1625# ALSA portion
1626options snd cards_limit=2
1627alias snd-card-0 snd-interwave
1628alias snd-card-1 snd-ens1371
1629options snd-interwave index=0
1630options snd-ens1371 index=1
1631# OSS/Free portion
1632alias sound-slot-0 snd-interwave
1633alias sound-slot-1 snd-ens1371
1634----- /etc/moprobe.conf
1635
1636In this example, the interwave card is always loaded as the first card
1637(index 0) and ens1371 as the second (index 1).
1638
1639
1640ALSA PCM devices to OSS devices mapping
1641=======================================
1642
1643/dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
1644/dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
1645/dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
1646/dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
1647/dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
1648/dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
1649/dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
1650/dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
1651/dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
1652
1653The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
1654sound card number and second means device number. The ALSA devices
1655have either 'c' or 'p' suffix indicating the direction, capture and
1656playback, respectively.
1657
1658Please note that the device mapping above may be varied via the module
1659options of snd-pcm-oss module.
1660
1661
1662DEVFS support
1663=============
1664
1665The ALSA driver fully supports the devfs extension.
1666You should add lines below to your devfsd.conf file:
1667
1668LOOKUP snd MODLOAD ACTION snd
1669REGISTER ^sound/.* PERMISSIONS root.audio 660
1670REGISTER ^snd/.* PERMISSIONS root.audio 660
1671
1672Warning: These lines assume that you have the audio group in your system.
1673 Otherwise replace audio word with another group name (root for
1674 example).
1675
1676
1677Proc interfaces (/proc/asound)
1678==============================
1679
1680/proc/asound/card#/pcm#[cp]/oss
1681-------------------------------
1682 String "erase" - erase all additional informations about OSS applications
1683 String "<app_name> <fragments> <fragment_size> [<options>]"
1684
1685 <app_name> - name of application with (higher priority) or without path
1686 <fragments> - number of fragments or zero if auto
1687 <fragment_size> - size of fragment in bytes or zero if auto
1688 <options> - optional parameters
1689 - disable the application tries to open a pcm device for
1690 this channel but does not want to use it.
1691 (Cause a bug or mmap needs)
1692 It's good for Quake etc...
1693 - direct don't use plugins
1694 - block force block mode (rvplayer)
1695 - non-block force non-block mode
1696 - whole-frag write only whole fragments (optimization affecting
1697 playback only)
1698 - no-silence do not fill silence ahead to avoid clicks
10f69f9e
TI		 1699 - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl
1700 instead of filled blocks
1da177e4

TI		 1707Early Buffer Allocation
1708=======================
1709
1710Some drivers (e.g. hdsp) require the large contiguous buffers, and
1711sometimes it's too late to find such spaces when the driver module is
1712actually loaded due to memory fragmentation. You can pre-allocate the
1713PCM buffers by loading snd-page-alloc module and write commands to its
1714proc file in prior, for example, in the early boot stage like
1715/etc/init.d/*.local scripts.
1716
1717Reading the proc file /proc/drivers/snd-page-alloc shows the current
1718usage of page allocation. In writing, you can send the following
1719commands to the snd-page-alloc driver:
1720
1721 - add VENDOR DEVICE MASK SIZE BUFFERS
1722
1723 VENDOR and DEVICE are PCI vendor and device IDs. They take
1724 integer numbers (0x prefix is needed for the hex).
1725 MASK is the PCI DMA mask. Pass 0 if not restricted.
1726 SIZE is the size of each buffer to allocate. You can pass
1727 k and m suffix for KB and MB. The max number is 16MB.
1728 BUFFERS is the number of buffers to allocate. It must be greater
1729 than 0. The max number is 4.
1730
1731 - erase
1732
1733 This will erase the all pre-allocated buffers which are not in
1734 use.
