I just bought a Sonos Beam for my TCL Roku 65” Series 6 TV. The volume of the sound is low. I need to set the minimum volume at 50. Often I have to raise it to 70 or 80. I’ve gone through everything I can think of both from the Sonos end and the TCL end. No joy. Incidentally, I have a pair of Sonos Ones in another room that would about blow you away. The amazing sound was the main reason I chose Sonos over another sound bar. Anything I’m missing?
