edh 0 reset msk <24b_mask> Error detection and handling
Error counting. The count itself is
reported in info. Errors can be
masked off and not counted; this is
the purpose of the mask. The counter
itself is 16b and will wrap around, but
can also be reset by issuing reset.

iN Audio matrix
mtx 0 (size 10:10) controls the audio
matrix; outputs 0-7 are embedded
sound, 8=adac and 9=AES.
Note: Any combination of the three
basic commands are allowed, for
instance the following command to
set up a 10x10 audio matrix in a
single line:
mtx 3 1 1 2 2 3 0,3-9

<sine_level>cBFS Audio generator
The amplitude of the generated sine
that can be chosen as fallback in
audio change-overs. Legal values are
-180cBFS or -200cBFS (centiBel
referred to full scale output). Units
are optional, but if included must be
written as cBFS (case sensitive).

the lower 8 are routed to the

nlr = Left channel phase inverted

<mute_status> Audio DAC control
This word dac identifies this audio
block as a DAC. The outputs can be
muted, <mute_status> given as on or
off, and the output level can be set in
cBu (tenth dBu). Units are optional, if
included must be written as cBu
(case sensitive).
Note 1: The lvl and mute are
independent, so that the card will
remember the lvl setting (and change
lvl setting) while muted.
Note 2: The resolution of the lvl
control is 0.5dB but the card will
perform correct rounding to nearest
legal value and report the resulting
setting. Legal input range is [-
