in my installation there is a link from /dev/cdrom to /dev/cdrom0 and a 
further link from /dev/cdrom0 to /dev/hdc. The attributes of /dev/hdc 
are "brw-rw----" ; after changing the attributes for other all users can 
use the Gnome-CD-player now....thank you for the hint
But what means  the abbreviation "hdc"??

modconf offers 2 modules for my AC'97 card: "ac97" and "ac97_codec"; I 
tried both

.... on my system a lot of silence; but when my soundcard doesn't work - 
why I can hear CDs??
gnome-sound-recorder crashed with an error message; looking in the 
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?
