I'm not sure if this will be the right section for this but i'm guessing it has something to do with my graphics card. I just started having this problem and i recently did just upgrade my graphics card. This problem only occurs though when the sound is through my tv, when i use my headphones instead the buzzing doesn't happen while in a game. I recorded the sound for you guys to listen to just in case and hopefully it helps in solving this problem. i will also list my specs down below, i also want to add that so far this seems to only happen in black ops iii and american truck simulator. I have been playing dead island definitive edition through my tv speakers and never once got that buzzing sound so im not sure what is happening. Thanks in advance to anyone who can help me figure this out because i am stumped on what to do.
