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.
