F8 Sound problems

[zephod at cfl.rr.com]

At first, I thought I had no sound at all but If I turn the volume all the way up, I can hear muffled noises. 

I found these lines in the messages file:

Nov 29 21:16:50 localhost pulseaudio[2958]: alsa-util.c: Device hw:1 doesn't support 44100 Hz, changed to 48000 Hz.
Nov 29 21:16:50 localhost pulseaudio[2958]: alsa-util.c: Cannot find mixer control "Master".
Nov 29 21:16:50 localhost pulseaudio[2958]: alsa-util.c: Cannot find mixer control "Capture".

lspci shows this:

# lspci | grep udio
00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)
01:0a.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03)

PulseAudio Volume Control shows 2 output devices at 100% volume.

Anybody have any suggestions on how to fix this?

Thanks,
Steve

PS I tried a suggestion I have seen on this list of deleting the alsa-pulsaudio-plugin package but nothing changed.
