We've had an issue with the Soundbar for months. TV sound keeps dropping out randomly, sounding patchy before usually going completely quiet.
We unplug the power to the Soundbar, and then wait for it to power up. Every time it picks up the sound again, it goes briefly patchy and drops out, before fading up and resuming proper sound.
I have tried connecting another Sonos item (Play 5) to the router via ethernet. This didn't resolve the issue. I've also moved the router closer to the Soundbar. The issue persists and is still random.
FWIW, router is Ausus RT-AC68P.

If you could please help us resolve this for once and for all, that would be great.
