How can you tell ALSA that an SPDIF input is 4 channels ?
Some ALSA
plugin? Of course, doing it in JACK's ALSA backend is also
reasonably simple, but would require small changes in many places to
override samplerates, etc.
I don't think it even needs to be a plugin, just tell ALSA about the
audio format. Where can the detailed specs be downloaded?
According to the Core Sound website this thing is still in development,
and the specs there are incomplete.
What they want to do is trick hardware 2-ch recorders into accepting
the 4-ch signal. So what is in reality 4 channels at 48 kHz will be
presented as 2 channels at 96 kHz.
