Need some help. I just got the PS3, and I have the video straight (HDMI to DVI) because Westinghouse apprently didn't have the memo that HDMI inputs were going to be pretty crucial when I bought my TV a year and a half ago. ANYWAY, I tried running an optical audio from PS3 to my receiver (BOSE 3-2-1) and and changed the audio output setting on the PS3 to optical audio, but I get no sound at all. Checked to make sure I was on the correct input and I was, so I don't get it. Right now I have the AV (composite) cables that came with the PS3 running the audio. Sounds okay, but it doesn't make sense to me why the optical wouldn't work with the exact same setup. Anyone know what I'm missing? Thanks.
