I have upgraded a Dell Precision 370 workstation from RHEL 3 update 3,
to update 4. I have now lost all sound.

/var/log/messages contains:

Dec 22 15:16:55 kayak kernel: Intel 810 + AC97 Audio, version 0.24,
10:27:57 Dec 21 2004
Dec 22 15:16:55 kayak insmod:
/lib/modules/2.4.21-27.ELsmp/kernel/drivers/sound/i810_audio.o:

You may find more information in syslog or the output from dmesg
Dec 22 15:16:55 kayak insmod:

sound-slot-0 failed
Dec 22 15:16:55 kayak modprobe: modprobe: Can't locate module
sound-service-0-3


And dmesg shows 265 lines of (and nothing else):

Intel 810 + AC97 Audio, version 0.24, 10:27:57 Dec 21 2004



If I boot back to the 2.4.21-20.ELsmp kernel, everything is fine. I know
the new kernel changed things around the Open Sound System - which I'm
sure are to blame.

Any suggestions on where to look, or what to fix?
