Tannoy active monitor question
Hi, apologies if this post is in the wrong place.
I have two tannoy active monitors that are plugged directly to my computers motherboard with a line connector. I hear some kind of ground loop or feedback noise, it changes pitch and sound depending on what the computer is doing. Not sure the best way to describe it. Any way I have tried to fix this with a pre amp but it doesnt change anything. Things I have also tried are plugging everything into different plug sockets and then all in the same outlet with a multi plug. Nothing I do will change the tone of the buzz. Both speakers produce the same buzz sound and both speakers worth perfectly fine when plugged into Iphones and smaller devices.
I also dont get any buzzing from standard desktop speakers.
If anyone has any solutions for me then that would be great.
