I’m not sure about your TV but it may be a setting you can disable to automatically change the sound.
I agree with you though. We have a Sony Bravia purchased back in 2016 for $900. It has thr Android TV spam/bloat/spyware but it’s not used and never connects to the Internet which has made the TV quite usable over the years. Apple TV is connected, Sonos too, and everything works fine without any crazy settings changes. I’m not looking forward to whenever this thing needs replaced (which will likely be it actually breaking versus being outdated).
