Hi
Had this issue for a while but not really bothered me as I use a headset and the problem only happens on the rare occasion I hook up some old hifi speakers.
The speakers run fine when the source is the sound system. Only happens when hooked up to PC
For the last couple of years my PSU has been constantly emitting a clicking/ tapping sound which I would is most likely to be a dodgy fan/ bearings.
If it's truly a dodgy fan, then should I really be getting the same sounds/ clicks in sync with PSU clicks when hooking up speakers? Or is something else amiss here?
Maybe lack of shielding on the old speakers? They're about 20 yrs old lol.
