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.
