but when i try to run sndconfig the program recorgnizes it and when it says
"A sound sample will now be played to „_
„_ determine if your sound card has been „_
„_ correctly configured."
the program just doesnt do anything and even if i try to run any mp3 file then also nothing happens
I looked at this thread for a minute and wondered where I knew that chipset from, and then I remembered...
oh yeah, that's my sound card!
modprobe cmpci
works for me every time, open the GUI and see if the mixer is muted, but I doubt it. Make certain you have the speakers connected to the right port if you have a multiple speaker out set-up like mine.
Also check dmesg, I get dropouts with DMA timing out constantly with this card where sound just refuses to play for about 20 seconds and then is fine for hours. Its annoying me enough so that I think I'm going to swap in a cheap old es1371 card.
It was really silly when i got the real cause of the problem.
one of the two system i was trying have sound card disabled in BIOS and on another the snound card was reported as on PCI slot where as it was onboard. when i corrected them things really changed now i have them in working order
Good, whew, sorry for the gimp list there, I was a little confused because this one is so normally out of the box up.
I nailed the problem with my DMA dropout issues too: this card's nifty extra kernel features do not play nice with ARts, so if you ever pull a recompile for fun and enable all of the cool extra stuff, kill ARts.

I have enabled the onboard soundcard from bios.
How can i check the irq & change it it is conflicting ?
Then check under whatever GUI Mixer prog you're using and make certain it didn't load with everything muted. If it doesn't load the module on the next boot, you can just sidestep RedHat's flakiness by putting the modprobe line in the file /etc/rc.d/rc.local
