Hello everyone.

I have a weird issue that I hope somebody will be able to shed some light on.

At what seems to be random intervals, but at least one hour apart, I get a static sound from speakers and sub woofer.

If I can try to explain the sound it would be Bzzzzzum  :whistler:, it lasts for about 1-1.5 sec, then there is nothing for about 15-20 seconds, then another Bzzzzum, another 15-20 seconds and then one last bzzzzzzum. Then no sounds at all, I would say for at least an hour.

Its not loud as such, but certainly audible when watching TV, I haven't noticed it when playing music loudly, so I don't think it is volume dependent.

I thought possibly the geyser, turned that off, made no difference. Today I'm going to try turning off the fridge for a while and see.

Any advice will be appreciated.
