I have a Minidisc deck with various digital in- and

S/PDIF. If you connect another MD deck or a CD player digitally and
record from it, it will faithfully reproduce the titling (not sure about
alphanumeric titles, but at least the starting points of the tracks will
be accurate and reliable and not just based on pauses like when
recording via the analog inputs).
It's possible that these sourcees send invalid or different data during
the pauses between tracks.
Now how do I get this information when recording an
S/PDIF signal into
the computer?
If that information is present, it must be in the channel status bits.
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.)
