Huh. Is that an ALSA shortcoming? Does this information get back out of the ALSA
driver (I can use
an RME Multiface here) in some manner?
As far as I can see, this driver does not give you access to the
channel status bits of the capture stream. (And even C-Media cards
give you only the first 32 bits.) Oh, and what's the deal with Dolby Surround via
S/PDIF? That would
also need some sort of access different to PCM, wouldn't it?
The Dolby/DTS bits pretend to be an uncompressed stereo stream. All
that changes is a single channel status bit ("non-audio"), which is
supported by most cards.
