Thu Nov 10 22:06:19 CET 2016
A simple conversion from the text file.
Since this is the only document specific to the configurations, it's
put to the root sound subdirectory.
A section describing the obsoleted configure stuff of old alsa-driver
tarball got removed.

+==============================================================
+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
+

+
+This module supports multiple cards. It does not support autoprobe:
+``port``, ``wss_port``, ``irq`` and ``dma1`` have to be specified.
+The other values are optional.

+or the value stored in the card's EEPROM for cards that have an EEPROM and
+their "CONFIG MODE" jumper set to "EEPROM SETTING". The other values can
+be chosen freely from the options enumerated above.
+
+If ``dma2`` is specified and different from ``dma1``, the card will operate in
+full-duplex mode. When ``dma1=3``, only ``dma2=0`` is valid and the only way to
+enable capture since only channels 0 and 1 are available for capture.
+
+Generic settings are ``port=0x220 wss_port=0x530 irq=10 dma1=1 dma2=0

+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.txt 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.

+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

+
+playback_bufsize

+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.

+autoclock
+ Enable auto-clock selection for UAC2 devices (default: yes)
+quirk_alias
+ Quirk alias list, pass strings like ``0123abcd:5678beef``, which
+ applies the existing quirk for the device 5678:beef to a new
+ device 0123:abcd.
+
+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 for caiaq UB audio interfaces,
+
+* Native Instruments RigKontrol2
+* Native Instruments Kore Controller

+This module supports multiple devices, autoprobe and hotplugging.
+
+Module snd-usb-usx2y
+--------------------
+
+Module for Tascam USB US-122, US-224 and US-428 devices.
+
+This module supports multiple devices, autoprobe and hotplugging.
+
+Note: you need to load the firmware via ``usx2yloader`` utility included
+in alsa-tools and alsa-firmware packages.
+
+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.

+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
+-----------------
+

+
+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.

- 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.
-
-
-Creating ALSA devices
-=====================
-
-This depends on your distribution, but normally you use the /dev/MAKEDEV
-script to create the necessary device nodes. On some systems you use a
-script named 'snddevices'.
-
-
-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.
-
-Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed.
-
- 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-ad1816a
- ------------------
-
- Module for sound cards based on Analog Devices AD1816A/AD1815 ISA chips.

- See HD-Audio.txt 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 Documentation/sound/alsa/HD-Audio.txt 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.txt
-
- 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.txt 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 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.

- 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.

-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
--------------------------------
- String "erase" - erase all additional information about OSS applications
- String "<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.
