So, I have a Sony HT-SS360 Home Theater System that's connected to the computer's optical output. When I run a test to see what sampling rates are supported, I get full surround sound as the Windows is playing sound through all 5 speakers. Once I'm playing a movie in VLC and select S/PDIF, the sound goes very choppy and skips, certain channels mute, can't understand anything that's being said, and sometimes completely cut out. I tried all different settings in both the Realtek Audio Manager and the Windows one. I'm at my wits end. Is it possible that this is a driver problem? Anyone else have this issue? Motherboard is Asus M3A78-EM, with Realtek HD audio driver v r2.27 installed.
