So I recently got a pair of studio monitors (JBL LSR 305). They are connected to my pc via a dual XLR to 3.5 mm cable. If I turn the volume on the JBL's up, there is a very loud staticy, crackling and popping sound. It also changes depending on what I do on my pc, for example scrolling up and down on a webpage will change the sound, so does clicking and moving my mouse, etc. Must be something with my pc, because when I plug the monitors into my phone, their is ZERO interference and the speakers work completely fine. I tried plugging the monitors into the same power strip as the computer, it didn't work. Right now the monitors and a sub are plugged into their own power strip, which is plugged into a power socket. Tried unplugging everything from the PC besides the monitors, still have the interference. Please help :c
