soundcard problems

[Art Werschulz]

Hi.

I am running FC3 on a dual i686 box, with kernel 2.6.11-1.27_FC3smp.
When I was running RedHat (versions 9.x and earlier), I had no
problems with sound.  Since moving to Fedora, sound no longer works.
This problem originally occurred on an older uniprocessor machine, under
both FC2 and FC3; it has persisted on my current machine (FC3 only).

When running system-config-soundcard, I am told that the following
audio device was detected:
   Vendor: Intel
   Model:  Corp. 8201 EB/ER (ICH5/ICH5R) AC'97 Audio Controller
   Module: snd-intel8x0
I then click the "Play test sound" button.  No sound is emitted, and I
am told that "Automatic detection of the sound card did not work.
Audio will not be available on the system."

I have used alsamixer to turn off muting, as well as to raise the
volumes on the various channels.  I have also chmod'ed /dev/sound and
/dev/dsp to 666.

Does anybody have any suggestions on how to fix the sound?

Many thanks.

PS: I have appended the output of lsmod and lspci, as well as the
contents of /etc/modprobe.conf; maybe this information will help.
