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
78 - Don't block opening busy PCM devices.
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
108 - Values: 0 through 7 or negative
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

811 The ac97_quirk option is used to enable/override the workaround
812 for specific devices. Some hardware have swapped output pins
813 between Master and Headphone, or Surround. The driver provides
814 the auto-detection of known problematic devices, but some might
815 be unknown or wrongly detected. In such a case, pass the proper

888
889 Note: the binding of amplifier is dependent on hardware.
890 If there is no sound even though all channels are unmuted, try to
891 specify other gpio connection via amp_gpio option.
892 For example, a Panasonic notebook might need "amp_gpio=0x0d"
893 option.
894
895 The power-management is supported.
896
897 Module snd-mixart
898 -----------------
899
900 Module for Digigram miXart8 sound cards.

904 See MIXART.txt for details.
905
906 When the driver is compiled as a module and the hotplug firmware
907 is supported, the firmware data is loaded via hotplug automatically.
908 Install the necessary firmware files in alsa-firmware package.
909 When no hotplug fw loader is available, you need to load the
910 firmware via mixartloader utility in alsa-tools package.

934
935 Module snd-nm256
936 ----------------
937
938 Module for NeoMagic NM256AV/ZX chips
939
940 playback_bufsize - max playback frame size in kB (4-128kB)
941 capture_bufsize - max capture frame size in kB (4-128kB)
942 force_ac97 - 0 or 1 (disabled by default)
943 buffer_top - specify buffer top address
944 use_cache - 0 or 1 (disabled by default)
945 vaio_hack - alias buffer_top=0x25a800
946 reset_workaround - enable AC97 RESET workaround for some laptops
947
948 Module supports autoprobe and multiple chips (max 8).
949
950 The power-management is supported.
951
952 Note: on some notebooks the buffer address cannot be detected
953 automatically, or causes hang-up during initialization.
954 In such a case, specify the buffer top address explicity via
955 buffer_top option.
956 For example,
957 Sony F250: buffer_top=0x25a800
958 Sony F270: buffer_top=0x272800
959 The driver supports only ac97 codec. It's possible to force
960 to initialize/use ac97 although it's not detected. In such a
961 case, use force_ac97=1 option - but *NO* guarantee whether it
962 works!
963
964 Note: The NM256 chip can be linked internally with non-AC97
965 codecs. This driver supports only the AC97 codec, and won't work
966 with machines with other (most likely CS423x or OPL3SAx) chips,
967 even though the device is detected in lspci. In such a case, try
968 other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP
969 but some doesn't have ISA PnP. You'll need to speicfy isapnp=0
970 and proper hardware parameters in the case without ISA PnP.
971
972 Note: some laptops need a workaround for AC97 RESET. For the
973 known hardware like Dell Latitude LS and Sony PCG-F305, this
974 workaround is enabled automatically. For other laptops with a
975 hard freeze, you can try reset_workaround=1 option.
976
977 Note: This driver is really crappy. It's a porting from the
978 OSS driver, which is a result of black-magic reverse engineering.
979 The detection of codec will fail if the driver is loaded *after*
980 X-server as described above. You might be able to force to load
981 the module, but it may result in hang-up. Hence, make sure that
982 you load this module *before* X if you encounter this kind of
983 problem.
984
985 Module snd-opl3sa2
986 ------------------
987
988 Module for Yamaha OPL3-SA2/SA3 sound cards.
989

1306
1307 Module supports autoprobe and multiple bus-master chips (max 8).
1308
1309 Note: on some SMP motherboards like MSI 694D the interrupts might
1310 not be generated properly. In such a case, please try to
1311 set the SMP (or MPS) version on BIOS to 1.1 instead of
1312 default value 1.4. Then the interrupt number will be
1313 assigned under 15. You might also upgrade your BIOS.
1314
2d7eb7cb 1315 Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound)
1da177e4 1316 channels as the first PCM. On these channels, up to 4
2d7eb7cb
SV		 1317 streams can be played at the same time, and the controller
1318 can perform sample rate conversion with separate rates for
1319 each channel.
1da177e4
LT		 1320 As default (dxs_support = 0), 48k fixed rate is chosen
1321 except for the known devices since the output is often
1322 noisy except for 48k on some mother boards due to the
1323 bug of BIOS.
2d7eb7cb 1324 Please try once dxs_support=5 and if it works on other
1da177e4
LT		 1325 sample rates (e.g. 44.1kHz of mp3 playback), please let us
1326 know the PCI subsystem vendor/device id's (output of
1327 "lspci -nv").
cdc27f3a
TI		 1328 If dxs_support=5 does not work, try dxs_support=4; if it
1329 doesn't work too, try dxs_support=1. (dxs_support=1 is
1330 usually for old motherboards. The correct implementated
1331 board should work with 4 or 5.) If it still doesn't
1da177e4
LT		 1332 work and the default setting is ok, dxs_support=3 is the
1333 right choice. If the default setting doesn't work at all,
1334 try dxs_support=2 to disable the DXS channels.
1335 In any cases, please let us know the result and the
1336 subsystem vendor/device ids.
1337
1338 Note: for the MPU401 on VIA823x, use snd-mpu401 driver
1339 additonally. The mpu_port option is for VIA686 chips only.

1374 When the driver is compiled as a module and the hotplug firmware
1375 is supported, the firmware data is loaded via hotplug automatically.
1376 Install the necessary firmware files in alsa-firmware package.
1377 When no hotplug fw loader is available, you need to load the
1378 firmware via vxloader utility in alsa-tools package. To invoke
1379 vxloader automatically, add the following to /etc/modprobe.conf
1380
1381 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader
1382
1383 (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to
1384 /etc/modules.conf, instead.)
1385 IBL size defines the interrupts period for PCM. The smaller size
1386 gives smaller latency but leads to more CPU consumption, too.
1387 The size is usually aligned to 126. As default (=0), the smallest
1388 size is chosen. The possible IBL values can be found in
1389 /proc/asound/cardX/vx-status proc file.

1439Configuring Non-ISAPNP Cards
1440============================
1441
1442When the kernel is configured with ISA-PnP support, the modules
1443supporting the isapnp cards will have module options "isapnp".
1444If this option is set, *only* the ISA-PnP devices will be probed.
1445For probing the non ISA-PnP cards, you have to pass "isapnp=0" option
1446together with the proper i/o and irq configuration.
1447
1448When the kernel is configured without ISA-PnP support, isapnp option
1449will be not built in.

1455The ALSA drivers can be loaded automatically on demand by defining
1456module aliases. The string 'snd-card-%1' is requested for ALSA native
1457devices where %i is sound card number from zero to seven.
1458
1459To auto-load an ALSA driver for OSS services, define the string
1460'sound-slot-%i' where %i means the slot number for OSS, which
1461corresponds to the card index of ALSA. Usually, define this
1462as the the same card module.
1463
1464An example configuration for a single emu10k1 card is like below:
1465----- /etc/modprobe.conf
1466alias snd-card-0 snd-emu10k1
1467alias sound-slot-0 snd-emu10k1
1468----- /etc/modprobe.conf
1469
1470The available number of auto-loaded sound cards depends on the module
1471option "cards_limit" of snd module. As default it's set to 1.
1472To enable the auto-loading of multiple cards, specify the number of
1473sound cards in that option.
1474
1475When multiple cards are available, it'd better to specify the index
1476number for each card via module option, too, so that the order of
1477cards is kept consistent.
1478
1479An example configuration for two sound cards is like below:
1480
1481----- /etc/modprobe.conf
1482# ALSA portion
1483options snd cards_limit=2
1484alias snd-card-0 snd-interwave
1485alias snd-card-1 snd-ens1371
1486options snd-interwave index=0
1487options snd-ens1371 index=1
1488# OSS/Free portion
1489alias sound-slot-0 snd-interwave
1490alias sound-slot-1 snd-ens1371
1491----- /etc/moprobe.conf
1492
1493In this example, the interwave card is always loaded as the first card
1494(index 0) and ens1371 as the second (index 1).

1497ALSA PCM devices to OSS devices mapping
1498=======================================
1499
1500/dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4
1501/dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3
1502/dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12
1503/dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20
1504/dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19
1505/dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28
1506/dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36
1507/dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39
1508/dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44
1509
1510The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means
1511sound card number and second means device number. The ALSA devices
1512have either 'c' or 'p' suffix indicating the direction, capture and
1513playback, respectively.
1514
1515Please note that the device mapping above may be varied via the module
1516options of snd-pcm-oss module.
1517
1518
1519DEVFS support
1520=============
1521
1522The ALSA driver fully supports the devfs extension.
1523You should add lines below to your devfsd.conf file:
1524
1525LOOKUP snd MODLOAD ACTION snd
1526REGISTER ^sound/.* PERMISSIONS root.audio 660
1527REGISTER ^snd/.* PERMISSIONS root.audio 660
1528
1529Warning: These lines assume that you have the audio group in your system.
1530 Otherwise replace audio word with another group name (root for
1531 example).
1532
1533
1534Proc interfaces (/proc/asound)
1535==============================
1536
1537/proc/asound/card#/pcm#[cp]/oss
1538-------------------------------
1539 String "erase" - erase all additional informations about OSS applications
1540 String "<app_name> <fragments> <fragment_size> [<options>]"
1541
1542 <app_name> - name of application with (higher priority) or without path
1543 <fragments> - number of fragments or zero if auto
1544 <fragment_size> - size of fragment in bytes or zero if auto
1545 <options> - optional parameters
1546 - disable the application tries to open a pcm device for
1547 this channel but does not want to use it.
1548 (Cause a bug or mmap needs)
1549 It's good for Quake etc...
1550 - direct don't use plugins
1551 - block force block mode (rvplayer)
1552 - non-block force non-block mode
1553 - whole-frag write only whole fragments (optimization affecting
1554 playback only)
1555 - no-silence do not fill silence ahead to avoid clicks
1556
1557 Example: echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss
1558 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss
1559 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss

TI		 1562Early Buffer Allocation
1563=======================
1564
1565Some drivers (e.g. hdsp) require the large contiguous buffers, and
1566sometimes it's too late to find such spaces when the driver module is
1567actually loaded due to memory fragmentation. You can pre-allocate the
1568PCM buffers by loading snd-page-alloc module and write commands to its
1569proc file in prior, for example, in the early boot stage like
1570/etc/init.d/*.local scripts.
1571
1572Reading the proc file /proc/drivers/snd-page-alloc shows the current
1573usage of page allocation. In writing, you can send the following
1574commands to the snd-page-alloc driver:
1575
1576 - add VENDOR DEVICE MASK SIZE BUFFERS
1577
1578 VENDOR and DEVICE are PCI vendor and device IDs. They take
1579 integer numbers (0x prefix is needed for the hex).
1580 MASK is the PCI DMA mask. Pass 0 if not restricted.
1581 SIZE is the size of each buffer to allocate. You can pass
1582 k and m suffix for KB and MB. The max number is 16MB.
1583 BUFFERS is the number of buffers to allocate. It must be greater
1584 than 0. The max number is 4.
1585
1586 - erase
1587
1588 This will erase the all pre-allocated buffers which are not in
1589 use.
