frontend audio stutter/freeze after playing recording

I've set up a MythDora system with a backend/frontend combo and a 2nd remote frontend. Everything is fine on the backend/frontend machine, but when I watch a recorded show on the remote front end, when the program is over, the screen goes blank and the audio stutters and loops rapidly until I press esc to get back to the menu. It doesn't crash the machine, but it takes away from the ease of use for the family. No other audio stutters, it just doesn't seem to be exiting cleanly from the recording. The front end is an Abit Nf-M2 NView using the onboard audio, both machines running Mythdora 3.2

Thanks

Since I didn't see any

Since I didn't see any comments, I went and bought a basic SB Audigy card and everything works fine now. Must have been something with the Nvidia driver. Thought I'd post a followup in case someone had a similar problem
