Hi, I've just got an HT-CT790 soundbar. I have connected via HDMI to my Sony TV. I have not connected all devices to the soundbar so am relying on the soundbar picking up the signal from the TV. The wall mount situation does not allow me to connect all devices directly to the soundbar. The volume is really low, not much better than the TV speakers. By contrast, the sound via Bluetooth from my phone is very loud. I really hope there is a solution as I'm struggling.
