PC is connect from my ATI HD 3650 to my Phillips HDTV via HDMI. Windows sounds great, movies sound great and internet sounds great. When I play audio files (iTunes or Windows Media Player) the vocals are very quiet but the music is just fine (almost like vocals are under water). I have checked the equalizers in both as well as checked the sound settings in the control panel. I have also switched HDMI cables, and HDMI iputs on the TV. Everything looks great. This is really frustrating, any help would be greatly appreciated. Thanks
