Yeah, I thought about that a bit after I posted. Though there might be some way to get sound from the A/V port via headphones or something. That'd semi-solve the buzz issue, too.
EDIT: Upon further inspection, the A/V jack is a 2.5mm plug instead of a traditional 3.5mm headphone plug. I'll dig out one of my 2.5mm to 3.5mm adapters in the next few days and see if I can get audio from it via headphones that way. Also, sorry to derail this thread with Supaboy talk.
