Description of problem:
I upgraded my system from FC1 to FC3 via yum. When playing sound,
either through XMMS, or even the GNOME system sounds, the output is
choppy, sounding like it is playing at a slower speed with static
thrown in to fill in the gaps. The same hardware worked fine under FC1.
If I do something like grab a window and move it around the screen,
the sound works normally.
system-config-soundcard detects an Ensoniq 5880 AudioPCI card. The
test sound exhibits the same behaviour as above.
Gstreamer is set for ALSA as both the source and sink. I can not run
the test for the sink, though, I get "Failed to construct test
pipeline for 'ALSA - Advanced Linux Sound Architecture'". However ESD
will test fine, but with the same behaviour.

Steps to Reproduce:
2.Listen to test sound
Actual Results: Choppy sound, playing at a slower speed, with static
Expected Results: A clear sound (or at least as good as a pair of $15
speakers will give)
My comment about moving a window seems a bit ambiguous. Sound is
fine while I'm moving the window around, it goes back to choppy once
