Annoying buzz.

[flibberdipper]

Alright, right now I have Vengeance (in my sig) hooked up to my Technics SA-AX530 with some cheap 3.5mm to RCA splitter thing. There is a lot of buzz, but only on the PC. Every other input is crystal clear. What could be causing this? And to give you an idea of the cable I'm using for audio from the Dish to it... It was $3.00. New. And it's crystal clear.

PSU can cause it, I can hear the mouse moving around from my onboard.

 

On my old PSU that had coil whine, if I played Crysis during the menus where the FPS gets into the thousands you could hear the screeching through the sound.

 

PCs seem to output dirty analog sound from my experience.

If the 3,5 output sounds normal with a headphone you most likely have a ground loop. If possible connect the pc and the amp to the same power outlet, another solution is to use a ground loop isolator adapter between them.

PSU is most certainly not the problem (no coil whine, and it's been going for almost a year solid). Even with my old speakers I never heard it when I moved my mouse through the speakers.

They are connected to the same outlet. And what is a ground loop isolator? I honestly have no idea what that is.

tldr - it breaks ground loops, which sometimes cause that "annoying buzz"

Do you think you can find a link to one online? Pretty please? Don't want to spend that much though.

I think those can be find on camcoders usb's too.. It clamps on the wire itself.

I wasn't all that sure what to look up or try to find. Besides that, I'm actually trying to get something done. Dusting things. SO MUCH DUST.
