Hey! I've just bought that marketing trick with Q-Symphony as I expected my Q80C and HW-Q600B to work together delivering a surround sound. Technically everything connects perfectly, no issues. However when i switch from TV speaker to the combo of speakers + soundbar, TV speakers volume is decreased to maybe 0.05% of the output. I had to put soundbar 1.5m away and try to lean with my ear to the TV speaker to hear that there's very very tiny sound playing, like in a small headphone. I was trying all possible combination with all modes, different apps, however the scenario was always the same: Q-Symphony just doesn't perform as it should. 99,5% of the sound goes to soundbar. I updated the firmware to latest available version. It didn't help. 

I know it's not a hardware issue, since the devices connect perfectly and the option can be selected. It's just that i can't figure out how to change settings for Q-Symphony to make TV speakers as loud as they would complement the sound. Cause right now they're just doing nothing...
