Adding Sony HTST7 HD to Sonos system

I run my television, gaming system and Apple TV through a Sony HTST7 HD. Bought a Connect and pair of Play 1. Set up was easy, grouped them and when I play music all three work — sound bar has to be set to analog, assuming because the Connect runs through RCA jacks. However only the sound bar works when the TV is on — sound bar has to be set to HDMI 1, assuming because it runs through the HDMI 1 jack into TV.

Question: is there a way to configure it so the pair of Play 1 also carry TV sound along with the sound bar? Again, all three work for music (when sound bar is set to analog/Connect input).

Thanks for any help, hope I explained it clearly.
