Query: Absolutely terrible.

Why have rear speakers when nothing ever comes out of them? Regardless of what I'm listening to, be it a DVD movie, music, or an on-line video, sound only comes out the front speakers. And yes, I have "5.1 surround sound speakers" selected in the control panel.I think the only sound that actually comes out of all five speakers is the Windows shutdown sound. Whoopee. I can hardly contain my excitement.
