The output from soundcard detection is:

Any Suggestions?
 
Thanks in Advance
 
Have you tried running alsamixer as root from a terminal prompt? Check to see if anything is muted. If it is, unmute it and escape back to the prompt. At the prompt type "alsactl -store" again as root after to testing sound card with "Detect Sound card" under system tools I think on the Red Fedora menu. This is supposed to fix the problem though it isn't the same card, you could check a thread called "Audigy issues with Fedora Core 2" in this forum. Some answers may apply. I am the one having the sound problem. We have it fixed manually, now working on getting to automatically setup at boot up. I am running the same kernel as you on an intel p4 2.4GHz processor.

since the sound was working with the only difference being a kernel version,
you might try the boot parameter "acpi=noirq". It makes the difference
between a couple of things working versus not working for me with a 2.6 kernel.
(one of which is sound)
 
 

Hey martouf when would I enter the command?

I had a similar problem with yoper linux and with SuSE Linux. The solution that worked for me was to download the source for alsa and compile it under my newer kernel. I had to have my kernel-source for the compile, but I don't know if that has anything to do with my distro or not since I didn't find anywhere that it was required.
 
Hope you get it all working! Good Luck

jpc1258: "boot parameter" == passed to the kernel at boot time.
 
compare the regular boot string with any 'safe mode' entry in your bootloader,
just to see what different boot parameter lists look like...
