I've searched the web and this forum and I can't find the solution to my problem. When i play music from the creativecommons website it sounds like my speakers are playing an additional "track" of buzzing noise. It sounds almost like a Rave remix gone bad. It's only on certain sites or apps. If I play the same track in iTunes after downloading it from the CC site the sound is gone(perfect), but I can't really hear the song until I've downloaded it and added it to iTunes... Even if i put my headphones on the sound is still there. I've got 10.5.7 and everything is up to date. I've had this issue for a while. Could it be a codec issue or something?
