OK, it's working now. When I boot the Planet CRRMA audio distribution
based on fedora fc1 (on the same computer) everything works fine. As it
uses a newer 2.4 Kernel I upgraded my Debian sid to 2.4.27. After some
searching I finally found my dvd drive (hdd) on /dev/scd7 (!)
I still do not understand why /dev/scd0 to /dev/scd6 all talk to the
same drive (hdb)

No, for audio work a patched 2.4 kernel beats 2.6. There are some
very recent reports about good results on 2.6.10, so this is likely
to change soon.

Yes, that's what I'm doing. Of corse I had checked *before* selecting my
configuration if putting the optical drives as slaves does not slow down
the hd's (masters).
Thank you,
