Logitech speakers z213 (subwoofer and 2 speakers), nothing fancy
since today (did have a windows update done last night) not working properly - loud white noise, somewhere between a hum and a buzz, it's constant when I plug it in my monitor. Doesn't hum when I plug it in MoBo, tho if I do that then I can't have my headset plugged in at the same time. I have front and back ports, but it just doesn't work if I try to combine the two.
I tried rolling back the updates, rolling back the software (for some reason I can't restore to yesterday or days before). It's not grounding issue (had that before and just reorganized my cables. It's also unrelated to volume level, as soon as I turn on my speakers they buzz if they're connected to monitor. I've tried to use NVIDIA and RealTek controler driver, neither of them work. Tried uninstalling and reinstalling the drivers and the device itself.
I really don't know what to do
