Sound problem

Hi , i have a little problem with sound on my Red Hat machine .
I hear sounds when i resize a window and that stuff, but when i try to play a normal audio cd i hear nothing . I have an Via Technologies VT82c686 ac97 audio controller and see the module loaded when i type lsmod .
I even hear the test soud when i check the soundcard configuration.
Gnome CD even starts playing the cd ... (I have a dual boot with windows and everthing works fine there so the hardware is ok )

Does anybody have an idea ... ?

p.s. I remember the first time I started Red Hat 8 after installation I had a messages window about ARTS ? and that arts was going to use /dev/null as an output ..
well at least i know that much that /dev/ null is no the right place to put anything in if you ever want it back

It sounds (no pun intended) that your chip is working i.e. producing sound.

so, is your application trying to see the correct device?

I can't say for deadrat, I use mandrake and KDE, but with both "grip" and the kde cd player "kscd" I have the problem that as I have both a cdrw and dvd drive, mandrake automatically call the devices "cdrom and cdrom 2" so I have to make sure that the applications are listening to the devices using more accurate (or maybe more correct) names.

If I look at the initial setup, it tells me that the app points to /dev/cdrom2 (which is my cdrw) so I have to configure it to point at /dev/scd0 - which is something to do with the "scsi emulation" used by a lot of burners. I can't use the dvd to listen to audio cd's, as it doesn't have an audio connection cable from the drive to the sound card (which I bought to use instead of the ac97 onboard device, which I couldn't get configured).

I am given to understand that under windows, the sound from the drive is somehow taken via the IDE cable, with linux, you require a connecting cable from the drive to the sound device (well I think that's correct anyway).

So just check what the app is looking at, is it using the correct name/nonclamenture?
because not only is my cdrw actually called /dev/scd0 but the dvd drive is called /dev/hdb.
