I use have an HT-XT3 and a 65X9305C connected. As it is the latest machine I connect it via the HDMI/ARC connection.

But I have some serious issues. When I want to push out TV sound - e.g from Netflix or from App like youtube or video - I get very often silence. I hear the system sounds but the soundbox is silent.

I turn XT3 off and the TV moves over to the TV-speakers, I restart it and it tells the TV it is active and stays silent. I could understand there is something wrong if this was 100% of the times but it is not always but often it happens.

Earlier today I played via the youtube app and had no sound issues. Then later today - it is silence. When I start the apps, the soundbar moves incoming signal from my HDMI port 2 (cable box) over to TV so there are some form of communicaiton between them. But no sound.

Any ideas? I have no idea how the *** I even can begin to test - since it is intermittent only.
