Our soundbar crackles, hisses and crackles, especially when switching. We had the problem directly after the purchase, but nothing could be found. But then everything was ok and now it's happening again. It was completely disconnected from the power supply for 3 weeks, FaceTime wasn't there and yesterday everything was connected and there it was again! What could it be?
