Okay, I'm having issues. My vizio is connected to a HTPC with an nVidia GT520 video card. The analog stereo outputs are obviously only 2 channel stereo, but the soundbar creates a virtual surround, right? So far that seems to be my best option, which is disappointing.
My digital coaxial is also seemingly only 2 channel stereo.
My HDMI out can be passed out of my TV via optical, but my TV converts the optical to 2 channel stereo.
So, I bought an HDMI to optical extractor. I hooked that up, and my HTPC recognizes that a 5.1 device is connected, but I can't get it to play right. It will show "digital" in the face plate for about 5 seconds, but on some sources (e.g. the Terry Bradshaw shingles commercial) I'm clearly not getting the center channel, because nothing he says is coming out of the speakers (just music).
What am I missing?
