Constant buzzing noise

[Roar_Cry]

First of all I'd like to apologize, I don't know much about computers. I downloaded this to play gamecube games after my friend showed me his. I downloaded a game and everything works fine as far as frame rate and play-ability. But there is a constant buzzing noise as soon as I start the game. I've tried every backend on the list and changed the DSP to LLE and nothing seems to resolve it. My computer is shit I know but is there anything that I missed that could possibly resolve this? Thanks!

Downloading games is against the rules.
