I think i have to add another potential source of
trouble...
Some info which may be of use.
Capture assignments are fixed:
1..8 : analog inputs
9..16 : ADAT input
17,18 : SPDIF input
Playback channels go via the matrix mixer. You either have to use
hdspmixer, or a script like this one:
----------------------------------------->8------------------------------------
#!/bin/bash
# mixer inputs:
# -------------------------------
# 0-7 analog in
# 16-23 adat in
# 24-25 spdif in
# 26-33 playback 1-8
# 42-51 playback 9-18
# mixer outputs:
# -------------------------------
# 0-7 analog out
# 16-23 adat out
# 24-25 spdif out
# 26-27 headphones out
# Alsa device name
device=hw:DSP
# 32768 is 0 dB
gain=32768
