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.)
Huh. Is that an ALSA shortcoming?
No, of the hardware.
Not always. When I wrote the RME driver for the
digiface/multiface/digi9652 etc, I knew that status bits were available,
but I don't recall exporting them to user space. At this point in time, I
don't even remember what the ALSA abstraction for that would be. The
"control" device? The mixer?
What could the Jack abstraction be? Synthetic Midi signals could likely
fit pretty well but probably cannot be delivered sample-accurate.
