Apple TV Sound Problem

[DavidQPR]

Hello. I have problem with ATV that started a few months ago. Randomly when switching to the ATV from another source there is no sound and the only way to bring back sound is to pull the plug out the back and back again. Then the sound is fine. This happens roughly 80% of the time.
I have reset the box but still the same issue. Is it time to get a new box? Its model number A2737 (64GB)
Also on another note if I may the ATV has started defaulting to showing Apple TV+ or whatever its called, I dont use it, and I have to press the home button again to return to the shelves

Thanks for any replies

When it happens again, turn off and then turn on the TV.

Yes I have tried that and didn't work. Pulling the power cord out the box seems to be the only way to get the sound back. I don't have any issue with my dvd player or Freeview recorder just the ATV.
