hdc is usually the first disk on the second ATA channel. The /dev/cdrom
link is created by the debian installer if it detects a cdrom. It also
adds an fstab entry for /cdrom to mount it; $mount /cdrom .

tried both

the ac97 and ac97_codec module are used by drivers for sound chipsets
that are ac97 based if I remeber correctly. The key is to select the
driver for your hardware e.g. the driver for via on-board sound, which
will in turn use the ac97 modules to setup your sound system.

Gnome-Bugzilla data base now I guess we are speaking about error 110738;
but I haven't any idea what I should do now. How could I hear my .wav-files?

CD audio is outputted as an analog stream by the cdrom, this is then fed
to the sound card via a small cable, the sound card can then either take
an active role in its output by for instance applying a pre-amp or a
passive role by just passing it the output jack(s) but the host OS,CPU
etc aren't involved other then controlling the track, play,pause etc.

If you can, it might be easier to pick up a cheap PCI sound card as
there are a lot of issues using ac97 based sound under linux; the major
one is getting it working in the first place, another one is that many
of the ac97 chipsets are fixed rate and unless you run everything that
isn't at that rate thru resampling it'll come out too fast or slow.

n.b. #debian on irc.freenode.org is good place to ask for help :)
