I've had a Q800C Soundbar for about a week now - connected via the included HDMI cables to a PS5 and to my Samsung UE55NU7100 TV.

Either when playing a game, or when watching TV - if the TV is left on PAUSE (no audio) for anywhere from 1 to 5 minutes, a loud buzzing sound will start. If playback in resumed, the sound of the media is VERY distorted and unpleasant.

A poweroff and restart of the soundbar resets the issue and resolves it.

Can any one advise what the problem could be? I have checked the connection points of the HDMIs, but not tried to replace the cables, nor have I checked if a software update is required.

I'm also not sure if this is a known issue - but I just don't know how to search for it on these forums.

Responses appreciated! This is an odd problem, but if I can't get to the bottom of it, I would like to return the product within the return window.
