| 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. |
Takashi Iwai | 304cd07 | 2007-10-26 15:10:15 +0200 | [diff] [blame] | 60 | slots - Reserve the slot index for the given driver. |
| 61 | This option takes multiple strings. |
| 62 | See "Module Autoloading Support" section for details. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 63 | |
| 64 | Module snd-pcm-oss |
| 65 | ------------------ |
| 66 | |
| 67 | The PCM OSS emulation module. |
| 68 | This module takes options which change the mapping of devices. |
| 69 | |
| 70 | dsp_map - PCM device number maps assigned to the 1st OSS device. |
| 71 | - Default: 0 |
| 72 | adsp_map - PCM device number maps assigned to the 2st OSS device. |
| 73 | - Default: 1 |
| 74 | nonblock_open |
Takashi Iwai | 6243008 | 2005-09-05 17:12:29 +0200 | [diff] [blame] | 75 | - Don't block opening busy PCM devices. Default: 1 |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 76 | |
| 77 | For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of |
| 78 | the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped |
| 79 | to PCM #0 of the card #0. |
| 80 | For changing the second or later card, specify the option with |
| 81 | commas, such like "dsp_map=0,1". |
| 82 | |
| 83 | nonblock_open option is used to change the behavior of the PCM |
| 84 | regarding opening the device. When this option is non-zero, |
| 85 | opening a busy OSS PCM device won't be blocked but return |
| 86 | immediately with EAGAIN (just like O_NONBLOCK flag). |
| 87 | |
| 88 | Module snd-rawmidi |
| 89 | ------------------ |
| 90 | |
| 91 | This module takes options which change the mapping of devices. |
| 92 | similar to those of the snd-pcm-oss module. |
| 93 | |
| 94 | midi_map - MIDI device number maps assigned to the 1st OSS device. |
| 95 | - Default: 0 |
| 96 | amidi_map - MIDI device number maps assigned to the 2st OSS device. |
| 97 | - Default: 1 |
| 98 | |
| 99 | Common parameters for top sound card modules |
| 100 | -------------------------------------------- |
| 101 | |
| 102 | Each of top level sound card module takes the following options. |
| 103 | |
| 104 | index - index (slot #) of sound card |
Clemens Ladisch | 0ef797c | 2005-11-21 07:30:20 +0100 | [diff] [blame] | 105 | - Values: 0 through 31 or negative |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 106 | - If nonnegative, assign that index number |
| 107 | - if negative, interpret as a bitmask of permissible |
| 108 | indices; the first free permitted index is assigned |
| 109 | - Default: -1 |
| 110 | id - card ID (identifier or name) |
| 111 | - Can be up to 15 characters long |
| 112 | - Default: the card type |
| 113 | - A directory by this name is created under /proc/asound/ |
| 114 | containing information about the card |
| 115 | - This ID can be used instead of the index number in |
| 116 | identifying the card |
| 117 | enable - enable card |
| 118 | - Default: enabled, for PCI and ISA PnP cards |
| 119 | |
Rene Herman | cf40a31 | 2006-03-28 12:38:20 +0200 | [diff] [blame] | 120 | Module snd-adlib |
| 121 | ---------------- |
| 122 | |
| 123 | Module for AdLib FM cards. |
| 124 | |
| 125 | port - port # for OPL chip |
| 126 | |
| 127 | This module supports multiple cards. It does not support autoprobe, so |
| 128 | the port must be specified. For actual AdLib FM cards it will be 0x388. |
| 129 | Note that this card does not have PCM support and no mixer; only FM |
| 130 | synthesis. |
| 131 | |
| 132 | Make sure you have "sbiload" from the alsa-tools package available and, |
| 133 | after loading the module, find out the assigned ALSA sequencer port |
| 134 | number through "sbiload -l". Example output: |
| 135 | |
| 136 | Port Client name Port name |
| 137 | 64:0 OPL2 FM synth OPL2 FM Port |
| 138 | |
| 139 | Load the std.sb and drums.sb patches also supplied by sbiload: |
| 140 | |
| 141 | sbiload -p 64:0 std.sb drums.sb |
| 142 | |
| 143 | If you use this driver to drive an OPL3, you can use std.o3 and drums.o3 |
| 144 | instead. To have the card produce sound, use aplaymidi from alsa-utils: |
| 145 | |
| 146 | aplaymidi -p 64:0 foo.mid |
| 147 | |

Takashi Iwai | 2734616 | 2006-01-12 18:28:44 +0100 | [diff] [blame] | 826 | NB: If you get many "azx_get_response timeout" messages at |
| 827 | loading, it's likely a problem of interrupts (e.g. ACPI irq |
| 828 | routing). Try to boot with options like "pci=noacpi". Also, you |
| 829 | can try "single_cmd=1" module option. This will switch the |
| 830 | communication method between HDA controller and codecs to the |
| 831 | single immediate commands instead of CORB/RIRB. Basically, the |
| 832 | single command mode is provided only for BIOS, and you won't get |
| 833 | unsolicited events, too. But, at least, this works independently |
| 834 | from the irq. Remember this is a last resort, and should be |
| 835 | avoided as much as possible... |

Takashi Iwai | 9590474 | 2007-05-19 17:06:42 +0200 | [diff] [blame] | 837 | MORE NOTES ON "azx_get_response timeout" PROBLEMS: |
| 838 | On some hardwares, you may need to add a proper probe_mask option |
| 839 | to avoid the "azx_get_response timeout" problem above, instead. |
| 840 | This occurs when the access to non-existing or non-working codec slot |
| 841 | (likely a modem one) causes a stall of the communication via HD-audio |
| 842 | bus. You can see which codec slots are probed by enabling |
Takashi Iwai | 62cf872 | 2008-05-20 12:15:15 +0200 | [diff] [blame] | 843 | CONFIG_SND_DEBUG_VERBOSE, or simply from the file name of the codec |
Takashi Iwai | 9590474 | 2007-05-19 17:06:42 +0200 | [diff] [blame] | 844 | proc files. Then limit the slots to probe by probe_mask option. |
| 845 | For example, probe_mask=1 means to probe only the first slot, and |
| 846 | probe_mask=4 means only the third slot. |

Takashi Iwai | 8a3fb4d | 2005-10-20 17:10:49 +0200 | [diff] [blame] | 1298 | This module supports one chip and autoprobe. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 1299 | |
| 1300 | The power-management is supported. |
| 1301 | |
| 1302 | Note: on some notebooks the buffer address cannot be detected |
| 1303 | automatically, or causes hang-up during initialization. |
Matt LaPlante | fff9289 | 2006-10-03 22:47:42 +0200 | [diff] [blame] | 1304 | In such a case, specify the buffer top address explicitly via |
| 1305 | the buffer_top option. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 1306 | For example, |
| 1307 | Sony F250: buffer_top=0x25a800 |
| 1308 | Sony F270: buffer_top=0x272800 |
| 1309 | The driver supports only ac97 codec. It's possible to force |
| 1310 | to initialize/use ac97 although it's not detected. In such a |
| 1311 | case, use force_ac97=1 option - but *NO* guarantee whether it |
| 1312 | works! |
| 1313 | |
| 1314 | Note: The NM256 chip can be linked internally with non-AC97 |
| 1315 | codecs. This driver supports only the AC97 codec, and won't work |
| 1316 | with machines with other (most likely CS423x or OPL3SAx) chips, |
| 1317 | even though the device is detected in lspci. In such a case, try |
| 1318 | 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] | 1319 | 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] | 1320 | and proper hardware parameters in the case without ISA PnP. |
| 1321 | |
| 1322 | Note: some laptops need a workaround for AC97 RESET. For the |
| 1323 | known hardware like Dell Latitude LS and Sony PCG-F305, this |
| 1324 | workaround is enabled automatically. For other laptops with a |
| 1325 | hard freeze, you can try reset_workaround=1 option. |
| 1326 | |
Takashi Iwai | d1f38cf | 2005-10-19 16:04:27 +0200 | [diff] [blame] | 1327 | Note: Dell Latitude CSx laptops have another problem regarding |
| 1328 | AC97 RESET. On these laptops, reset_workaround2 option is |
| 1329 | turned on as default. This option is worth to try if the |
| 1330 | previous reset_workaround option doesn't help. |
| 1331 | |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 1332 | Note: This driver is really crappy. It's a porting from the |
| 1333 | OSS driver, which is a result of black-magic reverse engineering. |
| 1334 | The detection of codec will fail if the driver is loaded *after* |
| 1335 | X-server as described above. You might be able to force to load |
| 1336 | the module, but it may result in hang-up. Hence, make sure that |
| 1337 | you load this module *before* X if you encounter this kind of |
| 1338 | problem. |

Takashi Iwai | c2b1239 | 2007-08-21 15:20:26 +0200 | [diff] [blame] | 1672 | The below are options for wavefront_synth features: |
| 1673 | wf_raw - Assume that we need to boot the OS (default:no) |
| 1674 | If yes, then during driver loading, the state of the board is |
| 1675 | ignored, and we reset the board and load the firmware anyway. |
| 1676 | fx_raw - Assume that the FX process needs help (default:yes) |
| 1677 | If false, we'll leave the FX processor in whatever state it is |
| 1678 | when the driver is loaded. The default is to download the |
| 1679 | microprogram and associated coefficients to set it up for |
| 1680 | "default" operation, whatever that means. |
| 1681 | debug_default - Debug parameters for card initialization |
| 1682 | wait_usecs - How long to wait without sleeping, usecs |
| 1683 | (default:150) |
| 1684 | This magic number seems to give pretty optimal throughput |
| 1685 | based on my limited experimentation. |
| 1686 | If you want to play around with it and find a better value, be |
| 1687 | my guest. Remember, the idea is to get a number that causes us |
| 1688 | to just busy wait for as many WaveFront commands as possible, |
| 1689 | without coming up with a number so large that we hog the whole |
| 1690 | CPU. |
| 1691 | Specifically, with this number, out of about 134,000 status |
| 1692 | waits, only about 250 result in a sleep. |
| 1693 | sleep_interval - How long to sleep when waiting for reply |
| 1694 | (default: 100) |
| 1695 | sleep_tries - How many times to try sleeping during a wait |
| 1696 | (default: 50) |
| 1697 | ospath - Pathname to processed ICS2115 OS firmware |
| 1698 | (default:wavefront.os) |
| 1699 | The path name of the ISC2115 OS firmware. In the recent |
| 1700 | version, it's handled via firmware loader framework, so it |
| 1701 | must be installed in the proper path, typically, |
| 1702 | /lib/firmware. |
| 1703 | reset_time - How long to wait for a reset to take effect |
| 1704 | (default:2) |
| 1705 | ramcheck_time - How many seconds to wait for the RAM test |
| 1706 | (default:20) |

Takashi Iwai | 6243008 | 2005-09-05 17:12:29 +0200 | [diff] [blame] | 1991 | AC97 Quirk Option |
| 1992 | ================= |
| 1993 | |
| 1994 | The ac97_quirk option is used to enable/override the workaround for |
| 1995 | specific devices on drivers for on-board AC'97 controllers like |
| 1996 | snd-intel8x0. Some hardware have swapped output pins between Master |
| 1997 | and Headphone, or Surround (thanks to confusion of AC'97 |
| 1998 | specifications from version to version :-) |
| 1999 | |
| 2000 | The driver provides the auto-detection of known problematic devices, |
| 2001 | but some might be unknown or wrongly detected. In such a case, pass |
| 2002 | the proper value with this option. |
| 2003 | |
| 2004 | The following strings are accepted: |
| 2005 | - default Don't override the default setting |
Takashi Iwai | 10e4097f | 2005-11-17 11:04:55 +0100 | [diff] [blame] | 2006 | - none Disable the quirk |
Takashi Iwai | 6243008 | 2005-09-05 17:12:29 +0200 | [diff] [blame] | 2007 | - hp_only Bind Master and Headphone controls as a single control |
| 2008 | - swap_hp Swap headphone and master controls |
| 2009 | - swap_surround Swap master and surround controls |
| 2010 | - ad_sharing For AD1985, turn on OMS bit and use headphone |
| 2011 | - alc_jack For ALC65x, turn on the jack sense mode |
| 2012 | - inv_eapd Inverted EAPD implementation |
| 2013 | - mute_led Bind EAPD bit for turning on/off mute LED |
| 2014 | |
| 2015 | For backward compatibility, the corresponding integer value -1, 0, |
| 2016 | ... are accepted, too. |
| 2017 | |
| 2018 | For example, if "Master" volume control has no effect on your device |
| 2019 | but only "Headphone" does, pass ac97_quirk=hp_only module option. |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 2022 | Configuring Non-ISAPNP Cards |
| 2023 | ============================ |
| 2024 | |
| 2025 | When the kernel is configured with ISA-PnP support, the modules |
| 2026 | supporting the isapnp cards will have module options "isapnp". |
| 2027 | If this option is set, *only* the ISA-PnP devices will be probed. |
| 2028 | For probing the non ISA-PnP cards, you have to pass "isapnp=0" option |
| 2029 | together with the proper i/o and irq configuration. |
| 2030 | |
| 2031 | When the kernel is configured without ISA-PnP support, isapnp option |
| 2032 | will be not built in. |
| 2033 | |
| 2034 | |
| 2035 | Module Autoloading Support |
| 2036 | ========================== |
| 2037 | |
| 2038 | The ALSA drivers can be loaded automatically on demand by defining |
| 2039 | module aliases. The string 'snd-card-%1' is requested for ALSA native |
| 2040 | devices where %i is sound card number from zero to seven. |
| 2041 | |
| 2042 | To auto-load an ALSA driver for OSS services, define the string |
| 2043 | 'sound-slot-%i' where %i means the slot number for OSS, which |
| 2044 | corresponds to the card index of ALSA. Usually, define this |
Tobias Klauser | d533f67 | 2005-09-10 00:26:46 -0700 | [diff] [blame] | 2045 | as the same card module. |
Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 2046 | |
| 2047 | An example configuration for a single emu10k1 card is like below: |
| 2048 | ----- /etc/modprobe.conf |
| 2049 | alias snd-card-0 snd-emu10k1 |
| 2050 | alias sound-slot-0 snd-emu10k1 |
| 2051 | ----- /etc/modprobe.conf |
| 2052 | |
| 2053 | The available number of auto-loaded sound cards depends on the module |
| 2054 | option "cards_limit" of snd module. As default it's set to 1. |
| 2055 | To enable the auto-loading of multiple cards, specify the number of |
| 2056 | sound cards in that option. |
| 2057 | |
| 2058 | When multiple cards are available, it'd better to specify the index |
| 2059 | number for each card via module option, too, so that the order of |
| 2060 | cards is kept consistent. |
| 2061 | |
| 2062 | An example configuration for two sound cards is like below: |
| 2063 | |
| 2064 | ----- /etc/modprobe.conf |
| 2065 | # ALSA portion |
| 2066 | options snd cards_limit=2 |
| 2067 | alias snd-card-0 snd-interwave |
| 2068 | alias snd-card-1 snd-ens1371 |
| 2069 | options snd-interwave index=0 |
| 2070 | options snd-ens1371 index=1 |
| 2071 | # OSS/Free portion |
| 2072 | alias sound-slot-0 snd-interwave |
| 2073 | alias sound-slot-1 snd-ens1371 |

Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 2075 | |
| 2076 | In this example, the interwave card is always loaded as the first card |
| 2077 | (index 0) and ens1371 as the second (index 1). |
| 2078 | |
Takashi Iwai | 304cd07 | 2007-10-26 15:10:15 +0200 | [diff] [blame] | 2079 | Alternative (and new) way to fixate the slot assignment is to use |
| 2080 | "slots" option of snd module. In the case above, specify like the |
| 2081 | following: |
| 2082 | |
| 2083 | options snd slots=snd-interwave,snd-ens1371 |
| 2084 | |
| 2085 | Then, the first slot (#0) is reserved for snd-interwave driver, and |
| 2086 | the second (#1) for snd-ens1371. You can omit index option in each |
| 2087 | driver if slots option is used (although you can still have them at |
| 2088 | the same time as long as they don't conflict). |
| 2089 | |
| 2090 | The slots option is especially useful for avoiding the possible |
| 2091 | hot-plugging and the resultant slot conflict. For example, in the |
| 2092 | case above again, the first two slots are already reserved. If any |
| 2093 | other driver (e.g. snd-usb-audio) is loaded before snd-interwave or |
| 2094 | snd-ens1371, it will be assigned to the third or later slot. |
| 2095 | |
Takashi Iwai | a93bbaa | 2008-05-27 17:59:24 +0200 | [diff] [blame] | 2096 | When a module name is given with '!', the slot will be given for any |
| 2097 | modules but that name. For example, "slots=!snd-pcsp" will reserve |
| 2098 | the first slot for any modules but snd-pcsp. |
| 2099 | |

| 2105 | /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 |
| 2106 | /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 |
| 2107 | /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 |
| 2108 | /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 |

| 2112 | /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 |
| 2113 | |
| 2114 | The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means |
| 2115 | sound card number and second means device number. The ALSA devices |
| 2116 | have either 'c' or 'p' suffix indicating the direction, capture and |
| 2117 | playback, respectively. |
| 2118 | |
| 2119 | Please note that the device mapping above may be varied via the module |
| 2120 | options of snd-pcm-oss module. |

Takashi Iwai | b6a9691 | 2005-05-30 18:27:03 +0200 | [diff] [blame] | 2153 | Early Buffer Allocation |
| 2154 | ======================= |
| 2155 | |
| 2156 | Some drivers (e.g. hdsp) require the large contiguous buffers, and |
| 2157 | sometimes it's too late to find such spaces when the driver module is |
| 2158 | actually loaded due to memory fragmentation. You can pre-allocate the |
| 2159 | PCM buffers by loading snd-page-alloc module and write commands to its |
| 2160 | proc file in prior, for example, in the early boot stage like |
| 2161 | /etc/init.d/*.local scripts. |
| 2162 | |
| 2163 | Reading the proc file /proc/drivers/snd-page-alloc shows the current |
| 2164 | usage of page allocation. In writing, you can send the following |
| 2165 | commands to the snd-page-alloc driver: |
| 2166 | |
| 2167 | - add VENDOR DEVICE MASK SIZE BUFFERS |
| 2168 | |
| 2169 | VENDOR and DEVICE are PCI vendor and device IDs. They take |
| 2170 | integer numbers (0x prefix is needed for the hex). |
| 2171 | MASK is the PCI DMA mask. Pass 0 if not restricted. |
| 2172 | SIZE is the size of each buffer to allocate. You can pass |
| 2173 | k and m suffix for KB and MB. The max number is 16MB. |
| 2174 | BUFFERS is the number of buffers to allocate. It must be greater |
| 2175 | than 0. The max number is 4. |
| 2176 | |
| 2177 | - erase |
| 2178 | |
| 2179 | This will erase the all pre-allocated buffers which are not in |
| 2180 | use. |
