I can play sounds and have no problems, except for mp3s. When I boot up my pc, the Windows Start sound is fine. There is no crackling, popping or skipping. When I play a game, all sounds are fine. When I play a mp3, using Winamp 2, I can hear a high pitch crackling and popping noise. Sometimes the mp3s will skip. Any ideas what is causing this and how I can fix it? All drivers have been update. I have also moved my sound card to different PCI slots. I have also tried other speakers. None have resolved the problem.
