When I hook up my HD TV via HDMI, everything looks and sounds fine until anything moves on the screen. So If I load up iTunes I can listen to music ok, but if I turn the visualizations on, the audio starts lighlty popping and crackling. I've updated my video and audio drivers. If I mute my PC I don't get the sound. If I don't have the pc muted and I also have nothing driving an audio signal (such as itunes, media player, etc.) I still get the sound. It does this whether I'm watching a movie or playing a game. anything that causes movement on the screen. no movement on the screen = no light popping or crackling. movement on the screen=light popping or crackling
please help
