XBMC with OSS error

[Yo Dawg]

After much tinkering and messing around I finally have at least sound
coming out of the optical out of my C-Media CM8738 sound card.  5.1
seems to work when I start playing a video file, but as soon as I pause
it, I get these error messages:

playback, will flush and prefix with 0 frames

On resuming, audio stops working although I get some static and pops
coming from the speakers.  The video framerate drops to 3.8 or so and
stutters horribly. Any suggestions on how to go about fixing this issue?
