what I have to do ?

for more info I'm using RH7.2

atiato,
Pls verify the current sound card that you are using now. Is it Creative Vibra 128, Yamaha Etc. If possible can you post your /dmesg output. Maybe we can verify from there whats wrong with your card. The possibility chances could be your sound card is not compatible, or the settings of the card is incorrect. Either thing you may also check the webpage for the list of h/ware requirements :-

This sound ship is built in the mother board Okay

Itel SE440BX

what do u mean by /dmesg ......plz

Ok first of all /dmesg is the log message that been generated automatically when you strartup the system. It contains all the H/Ware settings and services that start when you boot your systrem to Linux. Also you are saying your card is Itel SE440BX did you checked the redhat.com webpage for the Compatible device ? I strongly advise you to check on it first to verify your sound card is 100% compatible with the current version of Kernel your Linux have. Is its compatible you may run $ sndconfig. Its an automated probe for sound configuration. Give a try Post if that doesnt works.

If you type in "/dmesg", you'll get an error.
If you just type "dmesg" at the prompt, you should see a bunch of text scroll on your screen. It resides in the "/bin" directory on most Linux systems, so you could also type "/bin/dmesg".
It'll be helpful to catch it in a file, like this:
"dmesg > /tmp/dmesg.out"

That will save the output in a file called /tmp/dmesg.out .

I've had trouble with onboard sound before, though, so you may not be able to do it. Try running kudzu to detect the hardware. Type "man kudzu" for more information.

I mean Intel Board Se440 and the sound card is built in in the mother board okay I see that the sound card isapnp: Card 'CS4236B' is not compatible with this version of Linux
