I spent a lot of money on these speakers to be having this annoyance tbh
The USB ports and other ports in back are actually part of the motherboard, so for me to change this I'd need a new motherboard that somehow will fit there.
The front panel of the desktop, also has a couple of USBs, I may be able to do something there. Where could I find a similar plate IO, even so
The fact this sound happens whether I connect and disconnect the usb cable on front or rear panel, is the motherboard the problem apparently
I need to borrow a laptop or computer to check if the problem happens there as well.
I'd need to replace the motherboard and everything, the audio card/motherboard. How much would one cost, then the cost of repair/labor from the PC guy, might as well buy another computer. These speakers are $1400 the pair.
