I have the UN65RU7100 TV with the R-550 soundbar connected via HDMI ARC.
When I use apps (Netflix, DisneyPlus, ect) to stream movies, the soundbar does not respond the same as the satellite TV. The Soundbar does not increase in volume when you turn it up and sound detail is lost.
I connected via BT, and it works better, but still not as loud as the Satellite box on the same setting. Any suggestions?
