Hi, We have a Sonos Playbar, sub and 2 Sonos 1 second gen speakers The bar is hard wired to router. The tv is also. The tv is a Sony Bravo. Model XBR 65X850C. We have had the sound bar and tv connected for about 2 years now. About 2 weeks ago the sound had to be turned all the way up on the soundbar in order to hear it, but if you switch it to play music the sound is so loud you think the windows would scatter. I have tried everything that I have read to resolve this issue with no luck. Here is an diagnostic that I just took, 2043215814 not sure if it will help.
Thanks for your help
