Yes, the tv audio comes from the soundbar. The only issue is the dvd and no audio from the soundbar.
The tv is a Vizio PQX65, the dvd is a DVP-SR510H, and the soundbar is a HT-CT370. No optical cable in the mix.
I am able to get video and audio from the dvd and the soundbar, but have to connect the dvd via hdmi to the soundbar. That entails using the soundbar remote. I’d like to be able to use the tv remote to get the dvd video and audio.
