Hi, i was wondering if any of you guys can offer me some advice, I'm running iTunes 188.8.131.52 on PC. When I play any tracks in iTunes I get a hissing sound like the recording is from a tape. I have played various of the files in WMP and Sony Soundforge and they sound crystal clear. Additionally I have uninstalled and reinstalled iTunes and QT and put QT's audio properties into safe mode on the control panel but it still sounds like all of my files were recorded off the radio. Any suggestions? Thanks in anticipation.
