Question Buzzing noise from speakers only when playing games?


Jul 28, 2012
I just upgraded my desktop graphics card to a XFX Radeon 570. Now when I play games I am getting a buzzing sound that varies in intensity with the level of the graphic settings. Louder if graphics is set to high, quieter if set to low. I am using the motherboard audio chipset (Realtec).

Some background:

  1. Both computer and speakers are plugged into a grounded outlet. The speaker transformer does not have a ground plug.
  2. Before the upgrade, I did not have an issue.
  3. The buzzing does not occur if I am not playing games. YouTube videos are fine.
  4. Speakers are plugged into the motherboard.
My question is:

  1. How can I fix this? Will buying a low end sound card fix this. I am only interested in stereo sound. A high end 7.1 sound cord would be overkill.
  2. Is the graphics card defective?
Research seems to indicate this is a common problem.
