Huh. This begs the question: are there any applications making use of
it? 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?
Mixer control "IEC958 Capture Default"/"... Mask". For example, for recording via S/PDIF including track
marks?
Further research shows that the track number is not transmitted in the
channel status bits but in the "user"/"subcode" bits. I have never
seen
any sound card that allows access to those.
