I looked through the archives, and found similar complaints, but no
solutions. The sony cdrom driver doesn't provide all the stuff
necessary to get programs like xcdplayer to run (things like getting &
setting volume, getting the index). Looking at the source (2.1.6),
well, yeah - the ioctls aren't implemented. The archives mentioned that
Sony uses proprietary audio commands. So ...

Has anyone tried to get documentation on these commands from Sony?

If so, did you get them? If not, did they say "no way", or should I
bother trying?

If someone did obtain them, has anyone tried updating the driver?

What's the legality / possibility of figuring out what's going on from
a disassembled version of e.g. the DOS driver?

[is this question more appropriate for the -hackers list?]
