Release notes for the RME Digi96 family
=======================================

This is a BETA TEST VERSION and there many features that are not
implemented yet. Also some features may not work as intended yet.

This version supports all RME Digi96 family members. Also the
ADAT mode is supported. However the analog input port of Digi96/8 PAD
is not supported yet.


Adjusting the driver settings
-----------------------------

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.

digi96.mode (SPDIF|AESEBU|ADAT) currently SPDIF

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.)

digi96.sync (EXTERNAL|INTERNAL) currently 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.

digi96.input (OPTICAL|COAXIAL|INTERNAL|XLR) currently OPTICAL

Selects the active input.

digi96.sel (BYPASS|NORMAL) currently NORMAL

When set to BYPASS the input signal will be routed directly to the
output (also sets digi96.sync automatically to EXTERNAL.) In this mode
audio data written to /dev/dsp will be muted.

digi96.worldclk ON|OFF (currently OFF)

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

digi96.emph ON|OFF (currently OFF)

Enables/disables the de-emphasis option on the analog (monitor) output
connector.

digi96.data (AUDIO|AC3)currently AUDIO)

Specifies if the output signal is audio or AC3 data (sets the non-audio
bit in the channel status data.)
