Soundbar causing hum/buzz sound

Hi
Does anyone knows how to get rid of sound bar that is causing a hum/buzz sound?

I read that it maybe because of a ground loop. I tried plugging in to the main socket and still the same.

Removed all audio connector and left with just the main plug and the sound is still there.

This is a 2 flat pin plug. Is it because I need to ground this plug?

The soundbar is faulty.

Sometimes the buzzing goes away when it is connected to a source. Sometimes it doesn't. In either case it is a faulty unit or a faulty design.
