My Panasonic 65” TV is connected to a Sonos soundbar plus subwoofer and play one surround sound speakers. the Panasonic TV remote has suddenly stopped controlling the volume on the speakers (it controls TV channels perfectly so it’s not a fault with the TV remote). The Sonos app controls the speaker volume perfectly so it’s not a problem with the speakers.
it’s a problem with the Sonos software. I have rebooted the TV a couple of times, but hasn’t made any difference.
what should I try next ?
