no sound in one of my tvs when connected to Onkyo TX-NR676

[brin77]

I have a Sony projector connected to Onkyo TX-NR676 via HDMI out (Main). And my 5.1 surround speakers are set up via Onkyo receiver as well and everything is fine. When I connect my Sony KD49X720E TV to the Onkyo receiver via HDMI out (SUB), and switch the receiver to "Main + Sub" I get video in both, and audio via my 5.1 surround sound speakers, but no audio through my Sony KD49X720E tv. How do I get sound?

Change Audio TV out to "ON".
If the Onkyo is in standby you may also get sound on the TV.
