I have a ge62 2qd apache pro gaming laptop setup next to my Xbox. I run an aux cable from my laptop to my Astro a40 mix amp pro so that I can listen to music and podcasts while I play. Today a buzzing began playing into my headphones through the aux . It is loudest when the laptop is plugged in, very soft when it is not. The volume setting on the computer or mixamp doesn't affect the volume of the mix amp. I have tried multiple aux chords, it still buzzes. I have tried headphones directly plugged into the computer and there is no buzzing and I have plugged the aux from the mix amp into my phone and there is no buzzing. I did setup a new monitor for my Xbox today, I do not know how that would affect things though.
