That helped me on my zd8000. FC3 wav audio worked fine on this laptop, but
it went silent on the "upgrade" to FC4. Looks like this fix ought to go
back into the main tree.

I can confirm the same problem and solution for an Acer Travelmate 4020 
series.  I did have to run "gst-register-0.8" to see the volume control 
panel.  The not so clear error message said to run gst-register.

I had a similar problem on a zd7000, and I had to add
snd_intel8x0m
to /etc/hotplug/blacklist

To find that out, do a
# lsmod | grep snd

If you find something like (I think it was that line):
snd_ac97_codec         88893  1 snd_intel8x0,snd_intel8x0m

then blacklisting snd_intel8x0m like I said above might be the solution.
