Hi @IanEA
Welcome to the Sonos Community!
Please note that you were a bit off-topic, so I have moved your post to a new thread.
the only thing difference is we watched football on the red button setting, could that have caused a complete change ? Completely baffled!
That should not have made a difference, no.
I recommend you reboot all your devices by unplugging them from power - the Beam, the surrounds, the TV, and the source (if it was not the TV). It’s possible that rebooting one device will wok, but as we don’t know which one, I recommend just doing the lot. Please keep the TV unplugged for at least a minute.
I am not sure what you mean by this:
the sound settings on The TV have completely changed to a long bar for adjustment
Could you please elaborate, or even post a picture? Thanks.
I hope this helps.
