| 2 | Advanced Linux Sound Architecture - Driver |
| 3 | ========================================== |
| 4 | Configuration guide |
| 5 | |
| 6 | |
| 7 | Kernel Configuration |
| 8 | ==================== |
| 9 | |
| 10 | To enable ALSA support you need at least to build the kernel with |
| 11 | primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS, |
| 12 | you don't have to choose any of the OSS modules. |
| 13 | |
| 14 | Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and |
| 15 | PCM supports if you want to run OSS applications with ALSA. |
| 16 | |
| 17 | If you want to support the WaveTable functionality on cards such as |
| 18 | SB Live! then you need to enable "Sequencer support" |
| 19 | (CONFIG_SND_SEQUENCER). |
| 20 | |
| 21 | To make ALSA debug messages more verbose, enable the "Verbose printk" |
| 22 | and "Debug" options. To check for memory leaks, turn on "Debug memory" |
| 23 | too. "Debug detection" will add checks for the detection of cards. |
| 24 | |
| 25 | Please 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 |
| 27 | using isapnptools. |
| 28 | |
| 29 | |
| 30 | Creating ALSA devices |
| 31 | ===================== |
| 32 | |
| 33 | This depends on your distribution, but normally you use the /dev/MAKEDEV |
| 34 | script to create the necessary device nodes. On some systems you use a |
| 35 | script named 'snddevices'. |
| 36 | |
| 37 | |
| 38 | Module parameters |
| 39 | ================= |
| 40 | |
| 41 | The user can load modules with options. If the module supports more than |
| 42 | one card and you have more than one card of the same type then you can |
| 43 | specify multiple values for the option separated by commas. |
| 44 | |
| 45 | Prior 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 Iwai | 6243008 | 2005-09-05 17:12:29 +0200 | [diff] [blame] | 78 | - Don't block opening busy PCM devices. Default: 1 |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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 |
| 122 | |

| 1001 | The power-management is supported. |
| 1002 | |
| 1003 | Note: on some notebooks the buffer address cannot be detected |
| 1004 | automatically, or causes hang-up during initialization. |
| 1005 | In such a case, specify the buffer top address explicity via |
| 1006 | buffer_top option. |
| 1007 | For example, |
| 1008 | Sony F250: buffer_top=0x25a800 |
| 1009 | Sony F270: buffer_top=0x272800 |
| 1010 | The driver supports only ac97 codec. It's possible to force |
| 1011 | to initialize/use ac97 although it's not detected. In such a |
| 1012 | case, use force_ac97=1 option - but *NO* guarantee whether it |
| 1013 | works! |
| 1014 | |
| 1015 | Note: The NM256 chip can be linked internally with non-AC97 |
| 1016 | codecs. This driver supports only the AC97 codec, and won't work |
| 1017 | with machines with other (most likely CS423x or OPL3SAx) chips, |
| 1018 | even though the device is detected in lspci. In such a case, try |
| 1019 | other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP |
Takashi Iwai | 6243008 | 2005-09-05 17:12:29 +0200 | [diff] [blame] | 1020 | but some doesn't have ISA PnP. You'll need to specify isapnp=0 |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 1021 | and proper hardware parameters in the case without ISA PnP. |
| 1022 | |
| 1023 | Note: some laptops need a workaround for AC97 RESET. For the |
| 1024 | known hardware like Dell Latitude LS and Sony PCG-F305, this |
| 1025 | workaround is enabled automatically. For other laptops with a |
| 1026 | hard freeze, you can try reset_workaround=1 option. |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 1033 | Note: This driver is really crappy. It's a porting from the |
| 1034 | OSS driver, which is a result of black-magic reverse engineering. |
| 1035 | The detection of codec will fail if the driver is loaded *after* |
| 1036 | X-server as described above. You might be able to force to load |
| 1037 | the module, but it may result in hang-up. Hence, make sure that |

| 1429 | to the corresponding ALSA sequencer ports. |
| 1430 | |

| 1441 | ibl - Capture IBL size. (default = 0, minimum size) |
| 1442 | |
| 1443 | Module supports up to 8 cards. |
| 1444 | |
| 1445 | When the driver is compiled as a module and the hotplug firmware |
| 1446 | is supported, the firmware data is loaded via hotplug automatically. |
| 1447 | Install the necessary firmware files in alsa-firmware package. |
| 1448 | When no hotplug fw loader is available, you need to load the |
| 1449 | firmware via vxloader utility in alsa-tools package. To invoke |
| 1450 | vxloader automatically, add the following to /etc/modprobe.conf |
| 1451 | |
| 1452 | install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader |
| 1453 | |
| 1454 | (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to |
| 1455 | /etc/modules.conf, instead.) |
| 1456 | IBL size defines the interrupts period for PCM. The smaller size |
| 1457 | gives smaller latency but leads to more CPU consumption, too. |
| 1458 | The size is usually aligned to 126. As default (=0), the smallest |
| 1459 | size is chosen. The possible IBL values can be found in |
| 1460 | /proc/asound/cardX/vx-status proc file. |

| 1522 | ================= |
| 1523 | |
| 1524 | The ac97_quirk option is used to enable/override the workaround for |
| 1525 | specific devices on drivers for on-board AC'97 controllers like |
| 1526 | snd-intel8x0. Some hardware have swapped output pins between Master |
| 1527 | and Headphone, or Surround (thanks to confusion of AC'97 |
| 1528 | specifications from version to version :-) |
| 1529 | |
| 1530 | The driver provides the auto-detection of known problematic devices, |
| 1531 | but some might be unknown or wrongly detected. In such a case, pass |
| 1532 | the proper value with this option. |
| 1533 | |
| 1534 | The following strings are accepted: |
| 1535 | - default Don't override the default setting |
Takashi Iwai | 10e4097f | 2005-11-17 11:04:55 +0100 | [diff] [blame] | 1536 | - none Disable the quirk |
Takashi Iwai | 6243008 | 2005-09-05 17:12:29 +0200 | [diff] [blame] | 1537 | - hp_only Bind Master and Headphone controls as a single control |
| 1538 | - swap_hp Swap headphone and master controls |
| 1539 | - swap_surround Swap master and surround controls |
| 1540 | - ad_sharing For AD1985, turn on OMS bit and use headphone |
| 1541 | - alc_jack For ALC65x, turn on the jack sense mode |
| 1542 | - inv_eapd Inverted EAPD implementation |

| 1544 | |
| 1545 | For backward compatibility, the corresponding integer value -1, 0, |
| 1546 | ... are accepted, too. |
| 1547 | |
| 1548 | For example, if "Master" volume control has no effect on your device |
| 1549 | but only "Headphone" does, pass ac97_quirk=hp_only module option. |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 1552 | Configuring Non-ISAPNP Cards |
| 1553 | ============================ |
| 1554 | |
| 1555 | When the kernel is configured with ISA-PnP support, the modules |
| 1556 | supporting the isapnp cards will have module options "isapnp". |
| 1557 | If this option is set, *only* the ISA-PnP devices will be probed. |
| 1558 | For probing the non ISA-PnP cards, you have to pass "isapnp=0" option |
| 1559 | together with the proper i/o and irq configuration. |
| 1560 | |
| 1561 | When the kernel is configured without ISA-PnP support, isapnp option |
| 1562 | will be not built in. |
| 1563 | |
| 1564 | |
| 1565 | Module Autoloading Support |
| 1566 | ========================== |
| 1567 | |
| 1568 | The ALSA drivers can be loaded automatically on demand by defining |
| 1569 | module aliases. The string 'snd-card-%1' is requested for ALSA native |
| 1570 | devices where %i is sound card number from zero to seven. |
| 1571 | |
| 1572 | To auto-load an ALSA driver for OSS services, define the string |
| 1573 | 'sound-slot-%i' where %i means the slot number for OSS, which |
| 1574 | corresponds to the card index of ALSA. Usually, define this |
Tobias Klauser | d533f67 | 2005-09-10 00:26:46 -0700 | [diff] [blame] | 1575 | as the same card module. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 1576 | |
| 1577 | An example configuration for a single emu10k1 card is like below: |
| 1578 | ----- /etc/modprobe.conf |
| 1579 | alias snd-card-0 snd-emu10k1 |
| 1580 | alias sound-slot-0 snd-emu10k1 |
| 1581 | ----- /etc/modprobe.conf |
| 1582 | |
| 1583 | The available number of auto-loaded sound cards depends on the module |
| 1584 | option "cards_limit" of snd module. As default it's set to 1. |
| 1585 | To enable the auto-loading of multiple cards, specify the number of |
| 1586 | sound cards in that option. |
| 1587 | |
| 1588 | When multiple cards are available, it'd better to specify the index |
| 1589 | number for each card via module option, too, so that the order of |
| 1590 | cards is kept consistent. |
| 1591 | |
| 1592 | An example configuration for two sound cards is like below: |
| 1593 | |
| 1594 | ----- /etc/modprobe.conf |
| 1595 | # ALSA portion |
| 1596 | options snd cards_limit=2 |
| 1597 | alias snd-card-0 snd-interwave |
| 1598 | alias snd-card-1 snd-ens1371 |
| 1599 | options snd-interwave index=0 |
| 1600 | options snd-ens1371 index=1 |
| 1601 | # OSS/Free portion |
| 1602 | alias sound-slot-0 snd-interwave |
| 1603 | alias sound-slot-1 snd-ens1371 |
| 1604 | ----- /etc/moprobe.conf |
| 1605 | |
| 1606 | In this example, the interwave card is always loaded as the first card |
| 1607 | (index 0) and ens1371 as the second (index 1). |
| 1608 | |
| 1609 | |
| 1610 | ALSA PCM devices to OSS devices mapping |
| 1611 | ======================================= |
| 1612 | |
| 1613 | /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 |
| 1614 | /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 |
| 1615 | /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 |
| 1616 | /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 |
| 1617 | /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 |
| 1618 | /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 |
| 1619 | /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 |
| 1620 | /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 |
| 1621 | /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 |
| 1622 | |
| 1623 | The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means |
| 1624 | sound card number and second means device number. The ALSA devices |
| 1625 | have either 'c' or 'p' suffix indicating the direction, capture and |
| 1626 | playback, respectively. |
| 1627 | |
| 1628 | Please note that the device mapping above may be varied via the module |
| 1629 | options of snd-pcm-oss module. |
| 1630 | |
| 1631 | |
| 1632 | DEVFS support |
| 1633 | ============= |
| 1634 | |
| 1635 | The ALSA driver fully supports the devfs extension. |
| 1636 | You should add lines below to your devfsd.conf file: |
| 1637 | |
| 1638 | LOOKUP snd MODLOAD ACTION snd |
| 1639 | REGISTER ^sound/.* PERMISSIONS root.audio 660 |
| 1640 | REGISTER ^snd/.* PERMISSIONS root.audio 660 |
| 1641 | |
| 1642 | Warning: These lines assume that you have the audio group in your system. |
| 1643 | Otherwise replace audio word with another group name (root for |
| 1644 | example). |
| 1645 | |
| 1646 | |

| 1652 | String "erase" - erase all additional informations about OSS applications |
| 1653 | String "<app_name> <fragments> <fragment_size> [<options>]" |
| 1654 | |
| 1655 | <app_name> - name of application with (higher priority) or without path |

| 1678 | ======================= |
| 1679 | |
| 1680 | Some drivers (e.g. hdsp) require the large contiguous buffers, and |
| 1681 | sometimes it's too late to find such spaces when the driver module is |
| 1682 | actually loaded due to memory fragmentation. You can pre-allocate the |
| 1683 | PCM buffers by loading snd-page-alloc module and write commands to its |
| 1684 | proc file in prior, for example, in the early boot stage like |
| 1685 | /etc/init.d/*.local scripts. |
| 1686 | |
| 1687 | Reading the proc file /proc/drivers/snd-page-alloc shows the current |
| 1688 | usage of page allocation. In writing, you can send the following |
| 1689 | commands to the snd-page-alloc driver: |
| 1690 | |
| 1691 | - add VENDOR DEVICE MASK SIZE BUFFERS |
| 1692 | |
| 1693 | VENDOR and DEVICE are PCI vendor and device IDs. They take |
| 1694 | integer numbers (0x prefix is needed for the hex). |
| 1695 | MASK is the PCI DMA mask. Pass 0 if not restricted. |
| 1696 | SIZE is the size of each buffer to allocate. You can pass |
| 1697 | k and m suffix for KB and MB. The max number is 16MB. |
| 1698 | BUFFERS is the number of buffers to allocate. It must be greater |
| 1699 | than 0. The max number is 4. |
| 1700 | |
