From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040124 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.

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 I stop.
