NAME

       oss_digi96 - RME Digi96 professional audio driver.

DESCRIPTION

       Audio driver for the RME Digi96 family of profressional audio controllers.

       o  Only 16 and 24/32 bit audio formats are supported.

       o  All Digi96 family members support 32kHz, 44.1kHz, 48kHz, 64kHz, 88.2kHz and 96kHz. sampling rates.

MIXER PANEL

       Note! For recording you need to set digi96.sync to INTERNAL and the values of digi96.mode and digi96.input to match your studio setup. Oth-
       erwise recordings will fail with I/O error.

       There are several settings that can be changed using the ossmix program shipped with OSS. Note that  some  features  don't  work  with  all
       Digi96 family members. For example ADAT mode is not supported by the base model.

       o  digi96.mode  <SPDIF|AESEBU|ADAT>:  This setting controls the output mode which can be S/PDIF (consumer), AES/EBU (professional) or ADAT.
	  The input mode is detected automatically.  If ADAT input is detected the output mode	will  be  switched  to	ADAT  automatically  (this
	  doesn't work in the other direction).

       o  digi96.sync <EXTERNAL|INTERNAL>: This setting tells if the playback sampling rate is based on the internal oscillator or the sample rate
	  detected in the input port. See also the definition of the digi96.worldclk setting.

       o  digi96.input <OPTICAL|COAXIAL|INTERNAL|XLR>: Selects the active input.

       o  digi96.sel <BYPASS|NORMAL>: When set to BYPASS the input signal will be routed directly to the output (also sets  digi96.sync  automati-
	  cally to EXTERNAL). In this mode audio data written to /dev/dsp will be muted.

       o  digi96.worldclk  ON|OFF:  Setting  this control to ON will enable the optional worldclock input as the sample rate source (overrides the
	  digi96.sync setting).

       o  digi96.emph ON|OFF: Enables/disables the de-emphasis option on the analog (monitor) output connector.

       o  digi96.data <AUDIO|AC3>: Specifies if the output signal is audio or AC3 data (sets the non-audio bit in the channel status data).

NAME

       oss_hdaudio - Intel High Definition Audio (AZALIA)

DESCRIPTION

       Open  Sound  System driver for Intels high definition audio known as "Azalia". This driver supports Intel 915/925 chipsets with the Realtek
       ALC880 and CMedia 9880 8 channel codecs.

       The HDA driver supports:

       o  8-96Khz Playback/Recording

       o  8 or 16 or 32 bits

       o  2, 4, 6 or 8 channel audio.

       o  SPDIF digital output and Input

       o  AC3 passthrough

   HDAUDIO MIXER
       The Intel HDA mixer is a new type of mixer that doesn't have the normal volume controls found on AC97 or legacy SB devices.  The HDA  mixer
       presents a concept of Jacks and you can configure any jack to be either an output or an input jack.

       Some motherboards may not correctly initialize the jacks according to their color and functionality but in general here's the configuration
       that should generally be followed:

	      o Orange = Center/LFE
		     o Blue = Line-in

	      o Black = Rear
		     o Green = Front

	      o Grey = Side
		     o Pink = Mic

       Some Azalia codecs support front panel connectors and so if you see fp-green and fp-pink connectors, then these are for front panel speaker
       and mic/line-in Jacks.

	      There  is a function selector for most of the analog audio jacks (for example connector.pink.mode). This selector is used to control
	      if the jack is used as an input (microphone or line in) or output (front, rear, side, speaker, etc).

KNOWN PROBLEMS

       In general Azalia based systems (laptops/motherboards) would require a custom driver to work properly. Due to enormous number of  different
       systems	it  is not possible to develop such custom drivers for all systems. A generic driver is used for systems that don't have dedicated
       drivers.

       Unfortunately the mixer and control panel interface (see ossmix(1)) for "generic" systems is very cryptic and difficult to  understand.	To
       solve  problems	with  volumes or signal routing you need to start ossxmix(1) and change the controls one at time until you get the desired
       effect.

OPTIONS

       o hdaudio_jacksense
	      enables jack sensing mode when the hdaudio driver is loaded. In this mode all I/O pin's that are not in use will be disabled as well
	      as  the mixer controls that are related with them. In this way the mixer/control panel will become more intuitive.  However OSS will
	      need to be restarted with soundoff; soundon every time new inputs or outputs are attached to the audio jacks. Default : 0.

	      NOTE! hdaudio_jacksense=1 works only in some systems.  Many laptops and motherboards don't support jack sensing.

       o hdaudio_noskip
	      Disable skipping unconnected jack. All mixer controls will be shown, even for disabled I/O pins.	Can get values 0-7. 1-7 is a  bit-
	      mask,  where every bit masks a different check. Bit 3 (= value 4) overrides jacksense check too.	Default: 0 - unconnected jacks are
	      skipped.
