1============================================================== 2Advanced Linux Sound Architecture - Driver Configuration guide 3============================================================== 4 5 6Kernel Configuration 7==================== 8 9To enable ALSA support you need at least to build the kernel with 10primary sound card support (``CONFIG_SOUND``). Since ALSA can emulate 11OSS, you don't have to choose any of the OSS modules. 12 13Enable "OSS API emulation" (``CONFIG_SND_OSSEMUL``) and both OSS mixer 14and PCM supports if you want to run OSS applications with ALSA. 15 16If you want to support the WaveTable functionality on cards such as 17SB Live! then you need to enable "Sequencer support" 18(``CONFIG_SND_SEQUENCER``). 19 20To make ALSA debug messages more verbose, enable the "Verbose printk" 21and "Debug" options. To check for memory leaks, turn on "Debug memory" 22too. "Debug detection" will add checks for the detection of cards. 23 24Please note that all the ALSA ISA drivers support the Linux isapnp API 25(if the card supports ISA PnP). You don't need to configure the cards 26using isapnptools. 27 28 29Module parameters 30================= 31 32The user can load modules with options. If the module supports more than 33one card and you have more than one card of the same type then you can 34specify multiple values for the option separated by commas. 35 36 37Module snd 38---------- 39 40The core ALSA module. It is used by all ALSA card drivers. 41It takes the following options which have global effects. 42 43major 44 major number for sound driver; 45 Default: 116 46cards_limit 47 limiting card index for auto-loading (1-8); 48 Default: 1; 49 For auto-loading more than one card, specify this option 50 together with snd-card-X aliases. 51slots 52 Reserve the slot index for the given driver; 53 This option takes multiple strings. 54 See `Module Autoloading Support`_ section for details. 55debug 56 Specifies the debug message level; 57 (0 = disable debug prints, 1 = normal debug messages, 58 2 = verbose debug messages); 59 This option appears only when ``CONFIG_SND_DEBUG=y``. 60 This option can be dynamically changed via sysfs 61 /sys/modules/snd/parameters/debug file. 62 63Module snd-pcm-oss 64------------------ 65 66The PCM OSS emulation module. 67This module takes options which change the mapping of devices. 68 69dsp_map 70 PCM device number maps assigned to the 1st OSS device; 71 Default: 0 72adsp_map 73 PCM device number maps assigned to the 2st OSS device; 74 Default: 1 75nonblock_open 76 Don't block opening busy PCM devices; 77 Default: 1 78 79For example, when ``dsp_map=2``, /dev/dsp will be mapped to PCM #2 of 80the card #0. Similarly, when ``adsp_map=0``, /dev/adsp will be mapped 81to PCM #0 of the card #0. 82For changing the second or later card, specify the option with 83commas, such like ``dsp_map=0,1``. 84 85``nonblock_open`` option is used to change the behavior of the PCM 86regarding opening the device. When this option is non-zero, 87opening a busy OSS PCM device won't be blocked but return 88immediately with EAGAIN (just like O_NONBLOCK flag). 89 90Module snd-rawmidi 91------------------ 92 93This module takes options which change the mapping of devices. 94similar to those of the snd-pcm-oss module. 95 96midi_map 97 MIDI device number maps assigned to the 1st OSS device; 98 Default: 0 99amidi_map 100 MIDI device number maps assigned to the 2st OSS device; 101 Default: 1 102 103Common parameters for top sound card modules 104-------------------------------------------- 105 106Each of top level sound card module takes the following options. 107 108index 109 index (slot #) of sound card; 110 Values: 0 through 31 or negative; 111 If nonnegative, assign that index number; 112 if negative, interpret as a bitmask of permissible indices; 113 the first free permitted index is assigned; 114 Default: -1 115id 116 card ID (identifier or name); 117 Can be up to 15 characters long; 118 Default: the card type; 119 A directory by this name is created under /proc/asound/ 120 containing information about the card; 121 This ID can be used instead of the index number in 122 identifying the card 123enable 124 enable card; 125 Default: enabled, for PCI and ISA PnP cards 126 127Module snd-adlib 128---------------- 129 130Module for AdLib FM cards. 131 132port 133 port # for OPL chip 134 135This module supports multiple cards. It does not support autoprobe, so 136the port must be specified. For actual AdLib FM cards it will be 0x388. 137Note that this card does not have PCM support and no mixer; only FM 138synthesis. 139 140Make sure you have ``sbiload`` from the alsa-tools package available and, 141after loading the module, find out the assigned ALSA sequencer port 142number through ``sbiload -l``. 143 144Example output: 145:: 146 147 Port Client name Port name 148 64:0 OPL2 FM synth OPL2 FM Port 149 150Load the ``std.sb`` and ``drums.sb`` patches also supplied by ``sbiload``: 151:: 152 153 sbiload -p 64:0 std.sb drums.sb 154 155If you use this driver to drive an OPL3, you can use ``std.o3`` and ``drums.o3`` 156instead. To have the card produce sound, use ``aplaymidi`` from alsa-utils: 157:: 158 159 aplaymidi -p 64:0 foo.mid 160 161Module snd-ad1816a 162------------------ 163 164Module for sound cards based on Analog Devices AD1816A/AD1815 ISA chips. 165 166clockfreq 167 Clock frequency for AD1816A chip (default = 0, 33000Hz) 168 169This module supports multiple cards, autoprobe and PnP. 170 171Module snd-ad1848 172----------------- 173 174Module for sound cards based on AD1848/AD1847/CS4248 ISA chips. 175 176port 177 port # for AD1848 chip 178irq 179 IRQ # for AD1848 chip 180dma1 181 DMA # for AD1848 chip (0,1,3) 182 183This module supports multiple cards.

One is 277over AC-link and another is over the "direct" SPDIF output. The 278implementation depends on the motherboard, and you'll need to 279choose the correct one via spdif_aclink module option. 280 281The power-management is supported. 282 283Module snd-atiixp-modem 284----------------------- 285 286Module for ATI IXP 150/200/250 AC97 modem controllers. 287 288This module supports one card and autoprobe. 289 290Note: The default index value of this module is -2, i.e. the first 291slot is excluded. 292 293The power-management is supported. 294 295Module snd-au8810, snd-au8820, snd-au8830 296----------------------------------------- 297 298Module for Aureal Vortex, Vortex2 and Advantage device. 299 300pcifix 301 Control PCI workarounds; 302 0 = Disable all workarounds, 303 1 = Force the PCI latency of the Aureal card to 0xff, 304 2 = Force the Extend PCI#2 Internal Master for Efficient 305 Handling of Dummy Requests on the VIA KT133 AGP Bridge, 306 3 = Force both settings, 307 255 = Autodetect what is required (default) 308 309This module supports all ADB PCM channels, ac97 mixer, SPDIF, hardware 310EQ, mpu401, gameport.

1008 When the bit 8 (0x100) is set, the lower 8 bits are used 1009 as the "fixed" codec slots; i.e. the driver probes the 1010 slots regardless what hardware reports back 1011probe_only 1012 Only probing and no codec initialization (default=off); 1013 Useful to check the initial codec status for debugging 1014bdl_pos_adj 1015 Specifies the DMA IRQ timing delay in samples. 1016 Passing -1 will make the driver to choose the appropriate 1017 value based on the controller chip. 1018patch 1019 Specifies the early "patch" files to modify the HD-audio setup 1020 before initializing the codecs. 1021 This option is available only when ``CONFIG_SND_HDA_PATCH_LOADER=y`` 1022 is set. See hd-audio/notes.rst for details. 1023beep_mode 1024 Selects the beep registration mode (0=off, 1=on); 1025 default value is set via ``CONFIG_SND_HDA_INPUT_BEEP_MODE`` kconfig. 1026 1027[Single (global) options] 1028 1029single_cmd 1030 Use single immediate commands to communicate with codecs 1031 (for debugging only) 1032enable_msi 1033 Enable Message Signaled Interrupt (MSI) (default = off) 1034power_save 1035 Automatic power-saving timeout (in second, 0 = disable) 1036power_save_controller 1037 Reset HD-audio controller in power-saving mode (default = on) 1038align_buffer_size 1039 Force rounding of buffer/period sizes to multiples of 128 bytes. 1040 This is more efficient in terms of memory access but isn't 1041 required by the HDA spec and prevents users from specifying 1042 exact period/buffer sizes. (default = on) 1043snoop 1044 Enable/disable snooping (default = on) 1045 1046This module supports multiple cards and autoprobe. 1047 1048See hd-audio/notes.rst for more details about HD-audio driver. 1049 1050Each codec may have a model table for different configurations. 1051If your machine isn't listed there, the default (usually minimal) 1052configuration is set up. You can pass ``model=<name>`` option to 1053specify a certain model in such a case. There are different 1054models depending on the codec chip. The list of available models 1055is found in hd-audio/models.rst. 1056 1057The model name ``generic`` is treated as a special case. When this 1058model is given, the driver uses the generic codec parser without 1059"codec-patch". It's sometimes good for testing and debugging. 1060 1061If the default configuration doesn't work and one of the above 1062matches with your device, report it together with alsa-info.sh 1063output (with ``--no-upload`` option) to kernel bugzilla or alsa-devel 1064ML (see the section `Links and Addresses`_). 1065 1066``power_save`` and ``power_save_controller`` options are for power-saving 1067mode. See powersave.rst for details. 1068 1069Note 2: If you get click noises on output, try the module option 1070``position_fix=1`` or ``2``. ``position_fix=1`` will use the SD_LPIB 1071register value without FIFO size correction as the current 1072DMA pointer. ``position_fix=2`` will make the driver to use 1073the position buffer instead of reading SD_LPIB register. 1074(Usually SD_LPIB register is more accurate than the 1075position buffer.) 1076 1077``position_fix=3`` is specific to VIA devices. The position 1078of the capture stream is checked from both LPIB and POSBUF 1079values. ``position_fix=4`` is a combination mode, using LPIB 1080for playback and POSBUF for capture. 1081 1082NB: If you get many ``azx_get_response timeout`` messages at 1083loading, it's likely a problem of interrupts (e.g. ACPI irq 1084routing). Try to boot with options like ``pci=noacpi``. Also, you 1085can try ``single_cmd=1`` module option. This will switch the 1086communication method between HDA controller and codecs to the 1087single immediate commands instead of CORB/RIRB. Basically, the 1088single command mode is provided only for BIOS, and you won't get 1089unsolicited events, too. But, at least, this works independently 1090from the irq. Remember this is a last resort, and should be 1091avoided as much as possible... 1092 1093MORE NOTES ON ``azx_get_response timeout`` PROBLEMS: 1094On some hardware, you may need to add a proper probe_mask option 1095to avoid the ``azx_get_response timeout`` problem above, instead. 1096This occurs when the access to non-existing or non-working codec slot 1097(likely a modem one) causes a stall of the communication via HD-audio 1098bus. You can see which codec slots are probed by enabling 1099``CONFIG_SND_DEBUG_VERBOSE``, or simply from the file name of the codec 1100proc files. Then limit the slots to probe by probe_mask option. 1101For example, ``probe_mask=1`` means to probe only the first slot, and 1102``probe_mask=4`` means only the third slot. 1103 1104The power-management is supported. 1105 1106Module snd-hdsp 1107--------------- 1108 1109Module for RME Hammerfall DSP audio interface(s) 1110 1111This module supports multiple cards. 1112 1113Note: The firmware data can be automatically loaded via hotplug 1114when ``CONFIG_FW_LOADER`` is set. Otherwise, you need to load 1115the firmware via hdsploader utility included in alsa-tools 1116package. 1117The firmware data is found in alsa-firmware package. 1118 1119Note: snd-page-alloc module does the job which snd-hammerfall-mem 1120module did formerly. It will allocate the buffers in advance 1121when any HDSP cards are found. To make the buffer 1122allocation sure, load snd-page-alloc module in the early 1123stage of boot sequence.

It's possible to force 1657to initialize/use ac97 although it's not detected. In such a 1658case, use ``force_ac97=1`` option - but *NO* guarantee whether it 1659works! 1660 1661Note: The NM256 chip can be linked internally with non-AC97 1662codecs. This driver supports only the AC97 codec, and won't work 1663with machines with other (most likely CS423x or OPL3SAx) chips, 1664even though the device is detected in lspci. In such a case, try 1665other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP 1666but some doesn't have ISA PnP. You'll need to specify ``isapnp=0`` 1667and proper hardware parameters in the case without ISA PnP. 1668 1669Note: some laptops need a workaround for AC97 RESET. For the 1670known hardware like Dell Latitude LS and Sony PCG-F305, this 1671workaround is enabled automatically. For other laptops with a 1672hard freeze, you can try ``reset_workaround=1`` option. 1673 1674Note: Dell Latitude CSx laptops have another problem regarding 1675AC97 RESET. On these laptops, reset_workaround2 option is 1676turned on as default. This option is worth to try if the 1677previous reset_workaround option doesn't help. 1678 1679Note: This driver is really crappy. It's a porting from the 1680OSS driver, which is a result of black-magic reverse engineering. 1681The detection of codec will fail if the driver is loaded *after* 1682X-server as described above.

On these channels, up to 4 2304streams can be played at the same time, and the controller 2305can perform sample rate conversion with separate rates for 2306each channel. 2307As default (``dxs_support = 0``), 48k fixed rate is chosen 2308except for the known devices since the output is often 2309noisy except for 48k on some mother boards due to the 2310bug of BIOS. 2311Please try once ``dxs_support=5`` and if it works on other 2312sample rates (e.g. 44.1kHz of mp3 playback), please let us 2313know the PCI subsystem vendor/device id's (output of 2314``lspci -nv``). 2315If ``dxs_support=5`` does not work, try ``dxs_support=4``; if it 2316doesn't work too, try dxs_support=1. (dxs_support=1 is 2317usually for old motherboards. The correct implemented 2318board should work with 4 or 5.) If it still doesn't 2319work and the default setting is ok, ``dxs_support=3`` is the 2320right choice. If the default setting doesn't work at all, 2321try ``dxs_support=2`` to disable the DXS channels. 2322In any cases, please let us know the result and the 2323subsystem vendor/device ids. See `Links and Addresses`_ 2324below. 2325 2326Note: for the MPU401 on VIA823x, use snd-mpu401 driver 2327additionally. The mpu_port option is for VIA686 chips only. 2328 2329The power-management is supported. 2330 2331Module snd-via82xx-modem 2332------------------------ 2333 2334Module for VIA82xx AC97 modem 2335 2336ac97_clock 2337 AC'97 codec clock base (default 48000Hz) 2338 2339This module supports one card and autoprobe. 2340 2341Note: The default index value of this module is -2, i.e. the first 2342slot is excluded. 2343 2344The power-management is supported. 2345 2346Module snd-virmidi 2347------------------ 2348 2349Module for virtual rawmidi devices. 2350This module creates virtual rawmidi devices which communicate 2351to the corresponding ALSA sequencer ports. 2352 2353midi_devs 2354 MIDI devices # (1-4, default=4) 2355 2356This module supports multiple cards. 2357 2358Module snd-virtuoso 2359------------------- 2360 2361Module for sound cards based on the Asus AV66/AV100/AV200 chips, 2362i.e., Xonar D1, DX, D2, D2X, DS, DSX, Essence ST (Deluxe), 2363Essence STX (II), HDAV1.3 (Deluxe), and HDAV1.3 Slim. 2364 2365This module supports autoprobe and multiple cards. 2366 2367Module snd-vx222 2368---------------- 2369 2370Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards. 2371 2372mic 2373 Enable Microphone on V222 Mic (NYI) 2374ibl 2375 Capture IBL size. (default = 0, minimum size) 2376 2377This module supports multiple cards. 2378 2379When the driver is compiled as a module and the hotplug firmware 2380is supported, the firmware data is loaded via hotplug automatically. 2381Install the necessary firmware files in alsa-firmware package. 2382When no hotplug fw loader is available, you need to load the 2383firmware via vxloader utility in alsa-tools package. To invoke 2384vxloader automatically, add the following to /etc/modprobe.d/alsa.conf 2385 2386:: 2387 2388 install snd-vx222 /sbin/modprobe --first-time -i snd-vx222\ 2389 && /usr/bin/vxloader 2390 2391(for 2.2/2.4 kernels, add ``post-install /usr/bin/vxloader`` to 2392/etc/modules.conf, instead.) 2393IBL size defines the interrupts period for PCM. The smaller size 2394gives smaller latency but leads to more CPU consumption, too. 2395The size is usually aligned to 126. As default (=0), the smallest 2396size is chosen. The possible IBL values can be found in 2397/proc/asound/cardX/vx-status proc file. 2398 2399The power-management is supported. 2400 2401Module snd-vxpocket 2402------------------- 2403 2404Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards. 2405 2406ibl 2407 Capture IBL size. (default = 0, minimum size) 2408 2409This module supports multiple cards. The module is compiled only when 2410PCMCIA is supported on kernel. 2411 2412With the older 2.6.x kernel, to activate the driver via the card 2413manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the 2414sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no 2415longer require a config file. 2416 2417When the driver is compiled as a module and the hotplug firmware 2418is supported, the firmware data is loaded via hotplug automatically. 2419Install the necessary firmware files in alsa-firmware package. 2420When no hotplug fw loader is available, you need to load the 2421firmware via vxloader utility in alsa-tools package. 2422 2423About capture IBL, see the description of snd-vx222 module. 2424 2425Note: snd-vxp440 driver is merged to snd-vxpocket driver since 2426ALSA 1.0.10. 2427 2428The power-management is supported. 2429 2430Module snd-ymfpci 2431----------------- 2432 2433Module for Yamaha PCI chips (YMF72x, YMF74x & YMF75x). 2434 2435mpu_port 2436 0x300,0x330,0x332,0x334, 0 (disable) by default, 2437 1 (auto-detect for YMF744/754 only) 2438fm_port 2439 0x388,0x398,0x3a0,0x3a8, 0 (disable) by default 2440 1 (auto-detect for YMF744/754 only) 2441joystick_port 2442 0x201,0x202,0x204,0x205, 0 (disable) by default, 2443 1 (auto-detect) 2444rear_switch 2445 enable shared rear/line-in switch (bool) 2446 2447This module supports autoprobe and multiple chips. 2448 2449The power-management is supported. 2450 2451Module snd-pdaudiocf 2452-------------------- 2453 2454Module for Sound Core PDAudioCF sound card. 2455 2456The power-management is supported. 2457 2458 2459AC97 Quirk Option 2460================= 2461 2462The ac97_quirk option is used to enable/override the workaround for 2463specific devices on drivers for on-board AC'97 controllers like 2464snd-intel8x0. Some hardware have swapped output pins between Master 2465and Headphone, or Surround (thanks to confusion of AC'97 2466specifications from version to version :-) 2467 2468The driver provides the auto-detection of known problematic devices, 2469but some might be unknown or wrongly detected. In such a case, pass 2470the proper value with this option. 2471 2472The following strings are accepted: 2473 2474default 2475 Don't override the default setting 2476none 2477 Disable the quirk 2478hp_only 2479 Bind Master and Headphone controls as a single control 2480swap_hp 2481 Swap headphone and master controls 2482swap_surround 2483 Swap master and surround controls 2484ad_sharing 2485 For AD1985, turn on OMS bit and use headphone 2486alc_jack 2487 For ALC65x, turn on the jack sense mode 2488inv_eapd 2489 Inverted EAPD implementation 2490mute_led 2491 Bind EAPD bit for turning on/off mute LED 2492 2493For backward compatibility, the corresponding integer value -1, 0, ... 2494are accepted, too. 2495 2496For example, if ``Master`` volume control has no effect on your device 2497but only ``Headphone`` does, pass ac97_quirk=hp_only module option. 2498 2499 2500Configuring Non-ISAPNP Cards 2501============================ 2502 2503When the kernel is configured with ISA-PnP support, the modules 2504supporting the isapnp cards will have module options ``isapnp``. 2505If this option is set, *only* the ISA-PnP devices will be probed. 2506For probing the non ISA-PnP cards, you have to pass ``isapnp=0`` option 2507together with the proper i/o and irq configuration. 2508 2509When the kernel is configured without ISA-PnP support, isapnp option 2510will be not built in. 2511 2512 2513Module Autoloading Support 2514========================== 2515 2516The ALSA drivers can be loaded automatically on demand by defining 2517module aliases. The string ``snd-card-%1`` is requested for ALSA native 2518devices where ``%i`` is sound card number from zero to seven. 2519 2520To auto-load an ALSA driver for OSS services, define the string 2521``sound-slot-%i`` where ``%i`` means the slot number for OSS, which 2522corresponds to the card index of ALSA. Usually, define this 2523as the same card module. 2524 2525An example configuration for a single emu10k1 card is like below: 2526:: 2527 2528 ----- /etc/modprobe.d/alsa.conf 2529 alias snd-card-0 snd-emu10k1 2530 alias sound-slot-0 snd-emu10k1 2531 ----- /etc/modprobe.d/alsa.conf 2532 2533The available number of auto-loaded sound cards depends on the module 2534option ``cards_limit`` of snd module. As default it's set to 1. 2535To enable the auto-loading of multiple cards, specify the number of 2536sound cards in that option. 2537 2538When multiple cards are available, it'd better to specify the index 2539number for each card via module option, too, so that the order of 2540cards is kept consistent. 2541 2542An example configuration for two sound cards is like below: 2543:: 2544 2545 ----- /etc/modprobe.d/alsa.conf 2546 # ALSA portion 2547 options snd cards_limit=2 2548 alias snd-card-0 snd-interwave 2549 alias snd-card-1 snd-ens1371 2550 options snd-interwave index=0 2551 options snd-ens1371 index=1 2552 # OSS/Free portion 2553 alias sound-slot-0 snd-interwave 2554 alias sound-slot-1 snd-ens1371 2555 ----- /etc/modprobe.d/alsa.conf 2556 2557In this example, the interwave card is always loaded as the first card 2558(index 0) and ens1371 as the second (index 1). 2559 2560Alternative (and new) way to fixate the slot assignment is to use 2561``slots`` option of snd module. In the case above, specify like the 2562following: 2563:: 2564 2565 options snd slots=snd-interwave,snd-ens1371 2566 2567Then, the first slot (#0) is reserved for snd-interwave driver, and 2568the second (#1) for snd-ens1371. You can omit index option in each 2569driver if slots option is used (although you can still have them at 2570the same time as long as they don't conflict). 2571 2572The slots option is especially useful for avoiding the possible 2573hot-plugging and the resultant slot conflict. For example, in the 2574case above again, the first two slots are already reserved. If any 2575other driver (e.g. snd-usb-audio) is loaded before snd-interwave or 2576snd-ens1371, it will be assigned to the third or later slot. 2577 2578When a module name is given with '!', the slot will be given for any 2579modules but that name. For example, ``slots=!snd-pcsp`` will reserve 2580the first slot for any modules but snd-pcsp. 2581 2582 2583ALSA PCM devices to OSS devices mapping 2584======================================= 2585:: 2586 2587 /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 2588 /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 2589 /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 2590 /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 2591 /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 2592 /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 2593 /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 2594 /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 2595 /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 2596 2597The first number from ``/dev/snd/pcmC{X}D{Y}[c|p]`` expression means 2598sound card number and second means device number. The ALSA devices 2599have either ``c`` or ``p`` suffix indicating the direction, capture and 2600playback, respectively. 2601 2602Please note that the device mapping above may be varied via the module 2603options of snd-pcm-oss module. 2604 2605 2606Proc interfaces (/proc/asound) 2607============================== 2608 2609/proc/asound/card#/pcm#[cp]/oss 2610------------------------------- 2611erase 2612 erase all additional information about OSS applications 2613 2614<app_name> <fragments> <fragment_size> [<options>] 2615 <app_name> 2616 name of application with (higher priority) or without path 2617 <fragments> 2618 number of fragments or zero if auto 2619 <fragment_size> 2620 size of fragment in bytes or zero if auto 2621 <options> 2622 optional parameters 2623 2624 disable 2625 the application tries to open a pcm device for 2626 this channel but does not want to use it. 2627 (Cause a bug or mmap needs) 2628 It's good for Quake etc... 2629 direct 2630 don't use plugins 2631 block 2632 force block mode (rvplayer) 2633 non-block 2634 force non-block mode 2635 whole-frag 2636 write only whole fragments (optimization affecting 2637 playback only) 2638 no-silence 2639 do not fill silence ahead to avoid clicks 2640 buggy-ptr 2641 Returns the whitespace blocks in GETOPTR ioctl 2642 instead of filled blocks 2643 2644Example: 2645:: 2646 2647 echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss 2648 echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss 2649 echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss 2650 2651 2652Early Buffer Allocation 2653======================= 2654 2655Some drivers (e.g. hdsp) require the large contiguous buffers, and 2656sometimes it's too late to find such spaces when the driver module is 2657actually loaded due to memory fragmentation. You can pre-allocate the 2658PCM buffers by loading snd-page-alloc module and write commands to its 2659proc file in prior, for example, in the early boot stage like 2660``/etc/init.d/*.local`` scripts. 2661 2662Reading the proc file /proc/drivers/snd-page-alloc shows the current 2663usage of page allocation. In writing, you can send the following 2664commands to the snd-page-alloc driver: 2665 2666* add VENDOR DEVICE MASK SIZE BUFFERS 2667 2668VENDOR and DEVICE are PCI vendor and device IDs. They take 2669integer numbers (0x prefix is needed for the hex). 2670MASK is the PCI DMA mask. Pass 0 if not restricted. 2671SIZE is the size of each buffer to allocate. You can pass 2672k and m suffix for KB and MB. The max number is 16MB. 2673BUFFERS is the number of buffers to allocate. It must be greater 2674than 0. The max number is 4. 2675 2676* erase 2677 2678This will erase the all pre-allocated buffers which are not in 2679use. 2680 2681 2682Links and Addresses 2683=================== 2684 2685ALSA project homepage 2686 http://www.alsa-project.org 2687Kernel Bugzilla 2688 http://bugzilla.kernel.org/ 2689ALSA Developers ML 2690 mailto:alsa-devel@alsa-project.org 2691alsa-info.sh script 2692 http://www.alsa-project.org/alsa-info.sh 2693
