Could someone help me please? I hear a static sound when I fire guns like the Pretty Boy's Pocket Pistol and the Cow Mangler. The sound was okay a few days ago, then it started today. I don't have a sound card. I'm running on Windows 8. Well, earlier, I did update Windows, and after I restarted, I opened up TF2, went into a server, chose scout and used my pistol. It made a distorted noise and did too with some other weapons. I really need someone to help me. The sound is annoying and I can't concentrate.
