Hi everyone,

I'm hoping to get some help with an issue with my setup.

Just got back home after a week away, and now noticed that my speakers are humming/buzzing when I switch on my T777v3 (complete silence in standby).

There was a BluOS update, which I ran yesterday, and I'm pretty sure the humming wasn't present before that - could that be the cause?

The hum is coming from the front towers (PSB Imagine T2s) and the centre speaker (PSB Image C5). It's very audible when I mute the sound, but can also be heard when listening to movies where the characters are whispering.

I have done a power cycle, but no success.

Any suggestions on how to troubleshoot this issue will be most appreciated, thanks.


Update: By toggling the ARC settings, the buzzing stops, but the humming is still there. The same thing when I disable the Input in the menu.
