this suggests that you do not have correct connections established. at
least one of these should say "Lock" or "Sync". what is the
interface
connected to, and how is clocking being handled?
It's connected to the optical
input of an RME ADI-2 a/d d/a converter, the
clock setting of which is configured for slave mode, i.e., to synchronize with
the input signal.
The only output that works currently is /dev/audio1 (OSS emulation), which
sends output to all channels simultaneously. I have attempted using the -erc
operator of Ecasound to copy the output to different channels individually,
but short of trying all 27 channels I haven't been able to get any output
through to the converter.
When playing through /dev/audio1 the /proc/asound/card1/rme9652 parameters are
as follows. I am getting clicks in the output, for whatever reason.
