Hi, my playbar makes a continuous high pitched noise whenever plugged in. But, if I plug into a socket in a different room in my extension it doesn’t make the noise. But it does everywhere else. None of the rest of my set up is affected. Any ideas of how to solve out there?

You could be experiencing a ground loop hum. Read more about it here:

Thanks - I’ve had a look through and I’m not sure it’s any of those. I’ve found this video online which sounds just like the problem I’m experiencing.

I just can’t work out why it wouldn’t make this noise when essentially just plugged in another room!
