However, I had a quick go at capturing audio from SPDIF and the default stereo inputs (after making sure SPDIF in was enabled under alsamixer) this morning but I got nothing. I have zero experience with SPDIF devices and Linux (or any other OS) so I dunno what to watch out for
This depends entirely on how the hardware implements the routing.
In my quick test I was trying to capture audio from a audio CDR so there won't have been any copy protection on the disc. CDs are 44.1Khz of course but I was running JACK at 48Khz - that shouldn't be an issue should it or would I need to run JACK at 44.1 to capture an audio CD via SPDIF? Maybe rt resampling isn't supported?
I didn't find a box labeled "high-quality resampler for those lazy Jack users" in the datasheet ...
Another thing thats just come to mind is I think that the mic and line inputs were also set to capture so maybe I'd need to only enable capture for the SPDIF input but nothing else?
In theory, only one input can be enabled at the same time. What does "amixer contents" show for this device?
