| Advanced Linux Sound Architecture - Driver Configuration guide |
| ============================================================== |
| |
| |
| Kernel Configuration |
| ==================== |
| |
| To enable ALSA support you need at least to build the kernel with |
| primary sound card support (``CONFIG_SOUND``). Since ALSA can emulate |
| OSS, you don't have to choose any of the OSS modules. |
| |
| Enable "OSS API emulation" (``CONFIG_SND_OSSEMUL``) and both OSS mixer |
| and PCM supports if you want to run OSS applications with ALSA. |
| |
| If you want to support the WaveTable functionality on cards such as |
| SB Live! then you need to enable "Sequencer support" |
| (``CONFIG_SND_SEQUENCER``). |
| |
| To make ALSA debug messages more verbose, enable the "Verbose printk" |
| and "Debug" options. To check for memory leaks, turn on "Debug memory" |
| too. "Debug detection" will add checks for the detection of cards. |
| |
| Please note that all the ALSA ISA drivers support the Linux isapnp API |
| (if the card supports ISA PnP). You don't need to configure the cards |
| using isapnptools. |
| |
| |
| Module parameters |
| ================= |
| |
| The user can load modules with options. If the module supports more than |
| one card and you have more than one card of the same type then you can |
| specify multiple values for the option separated by commas. |
| |
| |
| Module snd |
| ---------- |
| |
| The core ALSA module. It is used by all ALSA card drivers. |
| It takes the following options which have global effects. |
| |
| major |
| major number for sound driver; |
| Default: 116 |
| cards_limit |
| limiting card index for auto-loading (1-8); |
| Default: 1; |
| For auto-loading more than one card, specify this option |
| together with snd-card-X aliases. |
| slots |
| Reserve the slot index for the given driver; |
| This option takes multiple strings. |
| See `Module Autoloading Support`_ section for details. |
| debug |
| Specifies the debug message level; |
| (0 = disable debug prints, 1 = normal debug messages, |
| 2 = verbose debug messages); |
| This option appears only when ``CONFIG_SND_DEBUG=y``. |
| This option can be dynamically changed via sysfs |
| /sys/modules/snd/parameters/debug file. |
| |
| Module snd-pcm-oss |
| ------------------ |
| |
| The PCM OSS emulation module. |
| This module takes options which change the mapping of devices. |
| |
| dsp_map |
| PCM device number maps assigned to the 1st OSS device; |
| Default: 0 |
| adsp_map |
| PCM device number maps assigned to the 2st OSS device; |
| Default: 1 |
| nonblock_open |
| Don't block opening busy PCM devices; |
| Default: 1 |
| |
| For example, when ``dsp_map=2``, /dev/dsp will be mapped to PCM #2 of |
| the card #0. Similarly, when ``adsp_map=0``, /dev/adsp will be mapped |
| to PCM #0 of the card #0. |
| For changing the second or later card, specify the option with |
| commas, such like ``dsp_map=0,1``. |
| |
| ``nonblock_open`` option is used to change the behavior of the PCM |
| regarding opening the device. When this option is non-zero, |
| opening a busy OSS PCM device won't be blocked but return |
| immediately with EAGAIN (just like O_NONBLOCK flag). |
| |
| Module snd-rawmidi |
| ------------------ |
| |
| This module takes options which change the mapping of devices. |
| similar to those of the snd-pcm-oss module. |
| |
| midi_map |
| MIDI device number maps assigned to the 1st OSS device; |
| Default: 0 |
| amidi_map |
| MIDI device number maps assigned to the 2st OSS device; |
| Default: 1 |
| |
| Common parameters for top sound card modules |
| -------------------------------------------- |
| |
| Each of top level sound card module takes the following options. |
| |
| index |
| index (slot #) of sound card; |
| Values: 0 through 31 or negative; |
| If nonnegative, assign that index number; |
| if negative, interpret as a bitmask of permissible indices; |
| the first free permitted index is assigned; |
| Default: -1 |
| id |
| card ID (identifier or name); |
| Can be up to 15 characters long; |
| Default: the card type; |
| A directory by this name is created under /proc/asound/ |
| containing information about the card; |
| This ID can be used instead of the index number in |
| identifying the card |
| enable |
| enable card; |
| Default: enabled, for PCI and ISA PnP cards |
| |
| Module snd-adlib |
| ---------------- |
| |
| Module for AdLib FM cards. |
| |
| port |
| port # for OPL chip |
| |
| This module supports multiple cards. It does not support autoprobe, so |
| the port must be specified. For actual AdLib FM cards it will be 0x388. |
| Note that this card does not have PCM support and no mixer; only FM |
| synthesis. |
| |
| Make sure you have ``sbiload`` from the alsa-tools package available and, |
| after loading the module, find out the assigned ALSA sequencer port |
| number through ``sbiload -l``. |
| |
| Example output: |
| :: |
| |
| Port Client name Port name |
| 64:0 OPL2 FM synth OPL2 FM Port |
| |
| Load the ``std.sb`` and ``drums.sb`` patches also supplied by ``sbiload``: |
| :: |
| |
| sbiload -p 64:0 std.sb drums.sb |
| |
| If you use this driver to drive an OPL3, you can use ``std.o3`` and ``drums.o3`` |
| instead. To have the card produce sound, use ``aplaymidi`` from alsa-utils: |
| :: |
| |
| aplaymidi -p 64:0 foo.mid |

| Module snd-hda-intel |
| -------------------- |
| |
| Module for Intel HD Audio (ICH6, ICH6M, ESB2, ICH7, ICH8, ICH9, ICH10, |
| PCH, SCH), ATI SB450, SB600, R600, RS600, RS690, RS780, RV610, RV620, |
| RV630, RV635, RV670, RV770, VIA VT8251/VT8237A, SIS966, ULI M5461 |
| |
| [Multiple options for each card instance] |
| |
| model |
| force the model name |
| position_fix |
| Fix DMA pointer; |
| -1 = system default: choose appropriate one per controller hardware, |
| 0 = auto: falls back to LPIB when POSBUF doesn't work, |
| 1 = use LPIB, |
| 2 = POSBUF: use position buffer, |
| 3 = VIACOMBO: VIA-specific workaround for capture, |
| 4 = COMBO: use LPIB for playback, auto for capture stream |
| probe_mask |
| Bitmask to probe codecs (default = -1, meaning all slots); |
| When the bit 8 (0x100) is set, the lower 8 bits are used |
| as the "fixed" codec slots; i.e. the driver probes the |
| slots regardless what hardware reports back |
| probe_only |
| Only probing and no codec initialization (default=off); |
| Useful to check the initial codec status for debugging |
| bdl_pos_adj |
| Specifies the DMA IRQ timing delay in samples. |
| Passing -1 will make the driver to choose the appropriate |
| value based on the controller chip. |
| patch |
| Specifies the early "patch" files to modify the HD-audio setup |
| before initializing the codecs. |
| This option is available only when ``CONFIG_SND_HDA_PATCH_LOADER=y`` |
| is set. See hd-audio/notes.rst for details. |
| beep_mode |
| Selects the beep registration mode (0=off, 1=on); |
| default value is set via ``CONFIG_SND_HDA_INPUT_BEEP_MODE`` kconfig. |
| |
| [Single (global) options] |
| |
| single_cmd |
| Use single immediate commands to communicate with codecs |
| (for debugging only) |
| enable_msi |
| Enable Message Signaled Interrupt (MSI) (default = off) |
| power_save |
| Automatic power-saving timeout (in second, 0 = disable) |
| power_save_controller |
| Reset HD-audio controller in power-saving mode (default = on) |
| align_buffer_size |
| Force rounding of buffer/period sizes to multiples of 128 bytes. |
| This is more efficient in terms of memory access but isn't |
| required by the HDA spec and prevents users from specifying |
| exact period/buffer sizes. (default = on) |
| snoop |
| Enable/disable snooping (default = on) |
| |
| This module supports multiple cards and autoprobe. |
| |
| See hd-audio/notes.rst for more details about HD-audio driver. |
| |
| Each codec may have a model table for different configurations. |
| If your machine isn't listed there, the default (usually minimal) |
| configuration is set up. You can pass ``model=<name>`` option to |
| specify a certain model in such a case. There are different |
| models depending on the codec chip. The list of available models |
| is found in hd-audio/models.rst. |
| |
| The model name ``generic`` is treated as a special case. When this |
| model is given, the driver uses the generic codec parser without |
| "codec-patch". It's sometimes good for testing and debugging. |
| |
| If the default configuration doesn't work and one of the above |
| matches with your device, report it together with alsa-info.sh |
| output (with ``--no-upload`` option) to kernel bugzilla or alsa-devel |
| ML (see the section `Links and Addresses`_). |
| |
| ``power_save`` and ``power_save_controller`` options are for power-saving |
| mode. See powersave.rst for details. |
| |
| Note 2: If you get click noises on output, try the module option |
| ``position_fix=1`` or ``2``. ``position_fix=1`` will use the SD_LPIB |
| register value without FIFO size correction as the current |
| DMA pointer. ``position_fix=2`` will make the driver to use |
| the position buffer instead of reading SD_LPIB register. |
| (Usually SD_LPIB register is more accurate than the |
| position buffer.) |
| |
| ``position_fix=3`` is specific to VIA devices. The position |
| of the capture stream is checked from both LPIB and POSBUF |
| values. ``position_fix=4`` is a combination mode, using LPIB |
| for playback and POSBUF for capture. |
| |
| NB: If you get many ``azx_get_response timeout`` messages at |
| loading, it's likely a problem of interrupts (e.g. ACPI irq |
| routing). Try to boot with options like ``pci=noacpi``. Also, you |
| can try ``single_cmd=1`` module option. This will switch the |
| communication method between HDA controller and codecs to the |
| single immediate commands instead of CORB/RIRB. Basically, the |
| single command mode is provided only for BIOS, and you won't get |
| unsolicited events, too. But, at least, this works independently |
| from the irq. Remember this is a last resort, and should be |
| avoided as much as possible... |
| |
| MORE NOTES ON ``azx_get_response timeout`` PROBLEMS: |
| On some hardware, you may need to add a proper probe_mask option |
| to avoid the ``azx_get_response timeout`` problem above, instead. |
| This occurs when the access to non-existing or non-working codec slot |
| (likely a modem one) causes a stall of the communication via HD-audio |
| bus. You can see which codec slots are probed by enabling |
| ``CONFIG_SND_DEBUG_VERBOSE``, or simply from the file name of the codec |
| proc files. Then limit the slots to probe by probe_mask option. |
| For example, ``probe_mask=1`` means to probe only the first slot, and |
| ``probe_mask=4`` means only the third slot. |
| |
| The power-management is supported. |

| Module snd-hdsp |
| --------------- |
| |
| Module for RME Hammerfall DSP audio interface(s) |
| |
| This module supports multiple cards. |
| |
| Note: The firmware data can be automatically loaded via hotplug |

| the firmware via hdsploader utility included in alsa-tools |
| package. |
| The firmware data is found in alsa-firmware package. |
| |
| Note: snd-page-alloc module does the job which snd-hammerfall-mem |
| module did formerly. It will allocate the buffers in advance |
| when any HDSP cards are found. To make the buffer |
| allocation sure, load snd-page-alloc module in the early |
| stage of boot sequence. See `Early Buffer Allocation`_ |
| section. |

| ---------------- |
| |
| Module for NeoMagic NM256AV/ZX chips |
| |
| playback_bufsize |
| max playback frame size in kB (4-128kB) |
| capture_bufsize |
| max capture frame size in kB (4-128kB) |
| force_ac97 |
| 0 or 1 (disabled by default) |
| buffer_top |
| specify buffer top address |
| use_cache |
| 0 or 1 (disabled by default) |
| vaio_hack |
| alias buffer_top=0x25a800 |
| reset_workaround |
| enable AC97 RESET workaround for some laptops |
| reset_workaround2 |
| enable extended AC97 RESET workaround for some other laptops |
| |
| This module supports one chip and autoprobe. |
| |
| The power-management is supported. |
| |
| Note: on some notebooks the buffer address cannot be detected |
| automatically, or causes hang-up during initialization. |
| In such a case, specify the buffer top address explicitly via |
| the buffer_top option. |
| For example, |
| Sony F250: buffer_top=0x25a800 |
| Sony F270: buffer_top=0x272800 |
| The driver supports only ac97 codec. It's possible to force |
| to initialize/use ac97 although it's not detected. In such a |
| case, use ``force_ac97=1`` option - but *NO* guarantee whether it |
| works! |
| |
| Note: The NM256 chip can be linked internally with non-AC97 |
| codecs. This driver supports only the AC97 codec, and won't work |
| with machines with other (most likely CS423x or OPL3SAx) chips, |
| even though the device is detected in lspci. In such a case, try |
| other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP |
| but some doesn't have ISA PnP. You'll need to specify ``isapnp=0`` |
| and proper hardware parameters in the case without ISA PnP. |
| |
| Note: some laptops need a workaround for AC97 RESET. For the |
| known hardware like Dell Latitude LS and Sony PCG-F305, this |
| workaround is enabled automatically. For other laptops with a |
| hard freeze, you can try ``reset_workaround=1`` option. |
| |
| Note: Dell Latitude CSx laptops have another problem regarding |
| AC97 RESET. On these laptops, reset_workaround2 option is |
| turned on as default. This option is worth to try if the |
| previous reset_workaround option doesn't help. |
| |
| Note: This driver is really crappy. It's a porting from the |
| OSS driver, which is a result of black-magic reverse engineering. |
| The detection of codec will fail if the driver is loaded *after* |
| X-server as described above. You might be able to force to load |
| the module, but it may result in hang-up. Hence, make sure that |
| you load this module *before* X if you encounter this kind of |
| problem. |

| The below are options for wavefront_synth features: |
| |
| wf_raw |
| Assume that we need to boot the OS (default:no); |
| If yes, then during driver loading, the state of the board is |
| ignored, and we reset the board and load the firmware anyway. |
| fx_raw |
| Assume that the FX process needs help (default:yes); |
| If false, we'll leave the FX processor in whatever state it is |
| when the driver is loaded. The default is to download the |
| microprogram and associated coefficients to set it up for |
| "default" operation, whatever that means. |
| debug_default |
| Debug parameters for card initialization |
| wait_usecs |
| How long to wait without sleeping, usecs (default:150); |
| This magic number seems to give pretty optimal throughput |
| based on my limited experimentation. |
| If you want to play around with it and find a better value, be |
| my guest. Remember, the idea is to get a number that causes us |
| to just busy wait for as many WaveFront commands as possible, |
| without coming up with a number so large that we hog the whole |
| CPU. |
| Specifically, with this number, out of about 134,000 status |
| waits, only about 250 result in a sleep. |
| sleep_interval |
| How long to sleep when waiting for reply (default: 100) |
| sleep_tries |
| How many times to try sleeping during a wait (default: 50) |
| ospath |
| Pathname to processed ICS2115 OS firmware (default:wavefront.os); |
| The path name of the ISC2115 OS firmware. In the recent |
| version, it's handled via firmware loader framework, so it |
| must be installed in the proper path, typically, |
| /lib/firmware. |
| reset_time |
| How long to wait for a reset to take effect (default:2) |
| ramcheck_time |
| How many seconds to wait for the RAM test (default:20) |
| osrun_time |
| How many seconds to wait for the ICS2115 OS (default:10) |
| |
| This module supports multiple cards and ISA PnP. |
| |
| Note: the firmware file ``wavefront.os`` was located in the earlier |
| version in /etc. Now it's loaded via firmware loader, and |
| must be in the proper firmware path, such as /lib/firmware. |
| Copy (or symlink) the file appropriately if you get an error |
| regarding firmware downloading after upgrading the kernel. |

| use_vmalloc |
| Use vmalloc() for allocations of the PCM buffers (default: yes). |
| For architectures with non-coherent memory like ARM or MIPS, the |
| mmap access may give inconsistent results with vmalloc'ed |
| buffers. If mmap is used on such architectures, turn off this |
| option, so that the DMA-coherent buffers are allocated and used |
| instead. |
| |
| This module supports multiple devices, autoprobe and hotplugging. |
| |
| NB: ``nrpacks`` parameter can be modified dynamically via sysfs. |
| Don't put the value over 20. Changing via sysfs has no sanity |
| check. |
| |
| NB: ``ignore_ctl_error=1`` may help when you get an error at accessing |
| the mixer element such as URB error -22. This happens on some |
| buggy USB device or the controller. |
| |
| NB: quirk_alias option is provided only for testing / development. |
| If you want to have a proper support, contact to upstream for |
| adding the matching quirk in the driver code statically. |

| |
| Module snd-via82xx |
| ------------------ |
| |
| Module for AC'97 motherboards based on VIA 82C686A/686B, 8233, 8233A, |
| 8233C, 8235, 8237 (south) bridge. |
| |
| mpu_port |
| 0x300,0x310,0x320,0x330, otherwise obtain BIOS setup |
| [VIA686A/686B only] |
| joystick |
| Enable joystick (default off) [VIA686A/686B only] |
| ac97_clock |
| AC'97 codec clock base (default 48000Hz) |
| dxs_support |
| support DXS channels, 0 = auto (default), 1 = enable, 2 = disable, |
| 3 = 48k only, 4 = no VRA, 5 = enable any sample rate and different |
| sample rates on different channels [VIA8233/C, 8235, 8237 only] |
| ac97_quirk |
| AC'97 workaround for strange hardware; |
| See `AC97 Quirk Option`_ section below. |
| |
| This module supports one chip and autoprobe. |
| |
| Note: on some SMP motherboards like MSI 694D the interrupts might |
| not be generated properly. In such a case, please try to |
| set the SMP (or MPS) version on BIOS to 1.1 instead of |
| default value 1.4. Then the interrupt number will be |
| assigned under 15. You might also upgrade your BIOS. |
| |
| Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) |
| channels as the first PCM. On these channels, up to 4 |
| streams can be played at the same time, and the controller |
| can perform sample rate conversion with separate rates for |
| each channel. |
| As default (``dxs_support = 0``), 48k fixed rate is chosen |
| except for the known devices since the output is often |
| noisy except for 48k on some mother boards due to the |
| bug of BIOS. |
| Please try once ``dxs_support=5`` and if it works on other |
| sample rates (e.g. 44.1kHz of mp3 playback), please let us |
| know the PCI subsystem vendor/device id's (output of |
| ``lspci -nv``). |
| If ``dxs_support=5`` does not work, try ``dxs_support=4``; if it |
| doesn't work too, try dxs_support=1. (dxs_support=1 is |
| usually for old motherboards. The correct implemented |
| board should work with 4 or 5.) If it still doesn't |
| work and the default setting is ok, ``dxs_support=3`` is the |
| right choice. If the default setting doesn't work at all, |
| try ``dxs_support=2`` to disable the DXS channels. |
| In any cases, please let us know the result and the |
| subsystem vendor/device ids. See `Links and Addresses`_ |
| below. |
| |
| Note: for the MPU401 on VIA823x, use snd-mpu401 driver |
| additionally. The mpu_port option is for VIA686 chips only. |
| |
| The power-management is supported. |
| |
| Module snd-via82xx-modem |
| ------------------------ |
| |
| Module for VIA82xx AC97 modem |
| |
| ac97_clock |
| AC'97 codec clock base (default 48000Hz) |
| |
| This module supports one card and autoprobe. |
| |
| Note: The default index value of this module is -2, i.e. the first |
| slot is excluded. |
| |
| The power-management is supported. |
| |
| Module snd-virmidi |
| ------------------ |
| |
| Module for virtual rawmidi devices. |

| i.e., Xonar D1, DX, D2, D2X, DS, DSX, Essence ST (Deluxe), |
| Essence STX (II), HDAV1.3 (Deluxe), and HDAV1.3 Slim. |
| |
| This module supports autoprobe and multiple cards. |
| |
| Module snd-vx222 |
| ---------------- |
| |
| Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards. |
| |
| mic |
| Enable Microphone on V222 Mic (NYI) |
| ibl |
| Capture IBL size. (default = 0, minimum size) |
| |
| This module supports multiple cards. |
| |
| When the driver is compiled as a module and the hotplug firmware |
| is supported, the firmware data is loaded via hotplug automatically. |
| Install the necessary firmware files in alsa-firmware package. |
| When no hotplug fw loader is available, you need to load the |
| firmware via vxloader utility in alsa-tools package. To invoke |
| vxloader automatically, add the following to /etc/modprobe.d/alsa.conf |
| |
| :: |
| |
| install snd-vx222 /sbin/modprobe --first-time -i snd-vx222\ |
| && /usr/bin/vxloader |
| |
| (for 2.2/2.4 kernels, add ``post-install /usr/bin/vxloader`` to |
| /etc/modules.conf, instead.) |
| IBL size defines the interrupts period for PCM. The smaller size |
| gives smaller latency but leads to more CPU consumption, too. |
| The size is usually aligned to 126. As default (=0), the smallest |
| size is chosen. The possible IBL values can be found in |
| /proc/asound/cardX/vx-status proc file. |
| |
| The power-management is supported. |
| |
| Module snd-vxpocket |
| ------------------- |
| |
| Module for Digigram VX-Pocket VX2 and 440 PCMCIA cards. |
| |
| ibl |
| Capture IBL size. (default = 0, minimum size) |
| |
| This module supports multiple cards. The module is compiled only when |
| PCMCIA is supported on kernel. |
| |
| With the older 2.6.x kernel, to activate the driver via the card |
| manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the |
| sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no |
| longer require a config file. |
| |
| When the driver is compiled as a module and the hotplug firmware |
| is supported, the firmware data is loaded via hotplug automatically. |
| Install the necessary firmware files in alsa-firmware package. |
| When no hotplug fw loader is available, you need to load the |
| firmware via vxloader utility in alsa-tools package. |
| |
| About capture IBL, see the description of snd-vx222 module. |
| |
| Note: snd-vxp440 driver is merged to snd-vxpocket driver since |
| ALSA 1.0.10. |
| |
| The power-management is supported. |
| |
| Module snd-ymfpci |
| ----------------- |

| 0x201,0x202,0x204,0x205, 0 (disable) by default, |
| 1 (auto-detect) |
| rear_switch |
| enable shared rear/line-in switch (bool) |
| |
| This module supports autoprobe and multiple chips. |
| |
| The power-management is supported. |
| |
| Module snd-pdaudiocf |
| -------------------- |
| |
| Module for Sound Core PDAudioCF sound card. |
| |
| The power-management is supported. |
| |
| |
| AC97 Quirk Option |
| ================= |
| |
| The ac97_quirk option is used to enable/override the workaround for |
| specific devices on drivers for on-board AC'97 controllers like |
| snd-intel8x0. Some hardware have swapped output pins between Master |
| and Headphone, or Surround (thanks to confusion of AC'97 |
| specifications from version to version :-) |
| |
| The driver provides the auto-detection of known problematic devices, |
| but some might be unknown or wrongly detected. In such a case, pass |
| the proper value with this option. |
| |
| The following strings are accepted: |
| |
| default |
| Don't override the default setting |
| none |
| Disable the quirk |
| hp_only |
| Bind Master and Headphone controls as a single control |
| swap_hp |
| Swap headphone and master controls |
| swap_surround |
| Swap master and surround controls |
| ad_sharing |
| For AD1985, turn on OMS bit and use headphone |
| alc_jack |
| For ALC65x, turn on the jack sense mode |
| inv_eapd |
| Inverted EAPD implementation |
| mute_led |
| Bind EAPD bit for turning on/off mute LED |
| |
| For backward compatibility, the corresponding integer value -1, 0, ... |
| are accepted, too. |
| |
| For example, if ``Master`` volume control has no effect on your device |
| but only ``Headphone`` does, pass ac97_quirk=hp_only module option. |
| |
| |
| Configuring Non-ISAPNP Cards |
| ============================ |
| |
| When the kernel is configured with ISA-PnP support, the modules |
| supporting the isapnp cards will have module options ``isapnp``. |
| If this option is set, *only* the ISA-PnP devices will be probed. |
| For probing the non ISA-PnP cards, you have to pass ``isapnp=0`` option |
| together with the proper i/o and irq configuration. |
| |
| When the kernel is configured without ISA-PnP support, isapnp option |
| will be not built in. |
| |
| |
| Module Autoloading Support |
| ========================== |
| |
| The ALSA drivers can be loaded automatically on demand by defining |
| module aliases. The string ``snd-card-%1`` is requested for ALSA native |
| devices where ``%i`` is sound card number from zero to seven. |
| |
| To auto-load an ALSA driver for OSS services, define the string |
| ``sound-slot-%i`` where ``%i`` means the slot number for OSS, which |
| corresponds to the card index of ALSA. Usually, define this |
| as the same card module. |
| |
| An example configuration for a single emu10k1 card is like below: |
| :: |
| |
| ----- /etc/modprobe.d/alsa.conf |
| alias snd-card-0 snd-emu10k1 |
| alias sound-slot-0 snd-emu10k1 |
| ----- /etc/modprobe.d/alsa.conf |
| |
| The available number of auto-loaded sound cards depends on the module |
| option ``cards_limit`` of snd module. As default it's set to 1. |
| To enable the auto-loading of multiple cards, specify the number of |
| sound cards in that option. |
| |
| When multiple cards are available, it'd better to specify the index |
| number for each card via module option, too, so that the order of |
| cards is kept consistent. |
| |
| An example configuration for two sound cards is like below: |
| :: |
| |
| ----- /etc/modprobe.d/alsa.conf |
| # ALSA portion |
| options snd cards_limit=2 |
| alias snd-card-0 snd-interwave |
| alias snd-card-1 snd-ens1371 |
| options snd-interwave index=0 |
| options snd-ens1371 index=1 |
| # OSS/Free portion |
| alias sound-slot-0 snd-interwave |
| alias sound-slot-1 snd-ens1371 |
| ----- /etc/modprobe.d/alsa.conf |
| |
| In this example, the interwave card is always loaded as the first card |
| (index 0) and ens1371 as the second (index 1). |
| |
| Alternative (and new) way to fixate the slot assignment is to use |
| ``slots`` option of snd module. In the case above, specify like the |
| following: |
| :: |
| |
| options snd slots=snd-interwave,snd-ens1371 |
| |
| Then, the first slot (#0) is reserved for snd-interwave driver, and |
| the second (#1) for snd-ens1371. You can omit index option in each |
| driver if slots option is used (although you can still have them at |
| the same time as long as they don't conflict). |
| |
| The slots option is especially useful for avoiding the possible |
| hot-plugging and the resultant slot conflict. For example, in the |
| case above again, the first two slots are already reserved. If any |
| other driver (e.g. snd-usb-audio) is loaded before snd-interwave or |
| snd-ens1371, it will be assigned to the third or later slot. |
| |
| When a module name is given with '!', the slot will be given for any |
| modules but that name. For example, ``slots=!snd-pcsp`` will reserve |
| the first slot for any modules but snd-pcsp. |
| |
| |
| ALSA PCM devices to OSS devices mapping |
| ======================================= |
| :: |
| |
| /dev/snd/pcmC0D0[c|p] -> /dev/audio0 (/dev/audio) -> minor 4 |
| /dev/snd/pcmC0D0[c|p] -> /dev/dsp0 (/dev/dsp) -> minor 3 |
| /dev/snd/pcmC0D1[c|p] -> /dev/adsp0 (/dev/adsp) -> minor 12 |
| /dev/snd/pcmC1D0[c|p] -> /dev/audio1 -> minor 4+16 = 20 |
| /dev/snd/pcmC1D0[c|p] -> /dev/dsp1 -> minor 3+16 = 19 |
| /dev/snd/pcmC1D1[c|p] -> /dev/adsp1 -> minor 12+16 = 28 |
| /dev/snd/pcmC2D0[c|p] -> /dev/audio2 -> minor 4+32 = 36 |
| /dev/snd/pcmC2D0[c|p] -> /dev/dsp2 -> minor 3+32 = 39 |
| /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 |
| |
| The first number from ``/dev/snd/pcmC{X}D{Y}[c|p]`` expression means |
| sound card number and second means device number. The ALSA devices |
| have either ``c`` or ``p`` suffix indicating the direction, capture and |
| playback, respectively. |
| |
| Please note that the device mapping above may be varied via the module |
| options of snd-pcm-oss module. |
| |
| |
| Proc interfaces (/proc/asound) |
| ============================== |
| |
| /proc/asound/card#/pcm#[cp]/oss |
| ------------------------------- |
| erase |
| erase all additional information about OSS applications |
| |
| <app_name> <fragments> <fragment_size> [<options>] |
| <app_name> |
| name of application with (higher priority) or without path |
| <fragments> |
| number of fragments or zero if auto |
| <fragment_size> |
| size of fragment in bytes or zero if auto |
| <options> |
| optional parameters |
| |
| disable |
| the application tries to open a pcm device for |
| this channel but does not want to use it. |
| (Cause a bug or mmap needs) |
| It's good for Quake etc... |
| direct |
| don't use plugins |
| block |
| force block mode (rvplayer) |
| non-block |
| force non-block mode |
| whole-frag |
| write only whole fragments (optimization affecting |
| playback only) |
| no-silence |
| do not fill silence ahead to avoid clicks |
| buggy-ptr |
| Returns the whitespace blocks in GETOPTR ioctl |
| instead of filled blocks |
| |
| Example: |
| :: |
| |
| echo "x11amp 128 16384" > /proc/asound/card0/pcm0p/oss |
| echo "squake 0 0 disable" > /proc/asound/card0/pcm0c/oss |
| echo "rvplayer 0 0 block" > /proc/asound/card0/pcm0p/oss |
| |
| |
| Early Buffer Allocation |
| ======================= |
| |
| Some drivers (e.g. hdsp) require the large contiguous buffers, and |
| sometimes it's too late to find such spaces when the driver module is |
| actually loaded due to memory fragmentation. You can pre-allocate the |
| PCM buffers by loading snd-page-alloc module and write commands to its |
| proc file in prior, for example, in the early boot stage like |
| ``/etc/init.d/*.local`` scripts. |
| |
| Reading the proc file /proc/drivers/snd-page-alloc shows the current |
| usage of page allocation. In writing, you can send the following |
| commands to the snd-page-alloc driver: |
| |
| * add VENDOR DEVICE MASK SIZE BUFFERS |
| |
| VENDOR and DEVICE are PCI vendor and device IDs. They take |
| integer numbers (0x prefix is needed for the hex). |
| MASK is the PCI DMA mask. Pass 0 if not restricted. |
| SIZE is the size of each buffer to allocate. You can pass |
| k and m suffix for KB and MB. The max number is 16MB. |
| BUFFERS is the number of buffers to allocate. It must be greater |
| than 0. The max number is 4. |
| |
| * erase |
| |
| This will erase the all pre-allocated buffers which are not in |
| use. |
