I have never had a receiver and always run everything (ps3/xbox/dvr) through the TV. Now I have an optical out going directly to the sub which is connected to the sound bar.
When I get the soundbar 5.1 system, I want to be sure I can run everything the same way and get 5.1 sound...but have seen some info stating that NO will pass 5.1 sound. This doesn't seem right to me...and I wanted to get some other opinions.
generally the deal is that if a TV is receiving over-the-air broadcasts with multichannel DD, it can pass that multichannel DD to a connected device digitally. But if you connect other devices directly to the TV, the TV expects to be playing the sound. The TV is stereo, not 5.1. Since it doesn't have 5.1 speakers, it doesn't want and can't deal with a 5.1 input, generally, (except embedded in OTA broadcasts). when you connect to the TV via HDMI, the first thing that happens is the source and TV have a little conversation about the TV's capabiliies. The TV says "I'm stereo," so the HDMI device sets itself to send stereo, and the TV never sees a multichannel signal that it can pass on to a soundbar or receiver. If it were otherwise, playing the sound back through the TV would yield zero dialog, since that's all mixed in the center channel, which the TV ain't got.
Universally, what folks do is go to the receiver (soundbar) first, then output video to the TV either via HDMI or otherwise. The only time you NEED to use sound from the TV is if you're receiving OTA broadcasts.
