Should be easy. Reading CD-XA mode2/form2 sectors is pretty
standard (at least much more standard than reading DA sectors).

I'd also like to know on which platforms it works (probably
only on fairly recent 3.0-current, right?). If possible, the
Makefile should automatically detect if the kernel supports
APATI audio extraction, much like it currently detects the
presence of CAM.
I will also need testers, because I have no 3.0-current box
with an APATI drive.

I believe that JC is not worth the trouble. I now have (more
or less) direct access to six different CD-ROM drives, and all
of them work fine (without jitter) during my tests. IMO: If
you want to do audio extraction, then buy a drive with decent
firmware that supports it reasonably (and I think almost all of
today's well-known brands should be OK for that).
On the other hand, that's only my experience with SCSI drives.
It might be a whole different story with APATI drives.
Apart from that, I'm not able to develop, test and maintain
code to perform JC without even having a CD-ROM drive that
requires it. Sorry for that.
Regards
Oliver
