Hey, I noticed a strange crackling noise when I change the volume on streaming videos. For example when I watch a YouTube video and I want to decrease the volume, I get almost always a strange crackling noise. It's just when I stream a video. The same video I bought on iTunes runs perfectly fine and I don't have that strange noise. I already updated Flash but it didn't solve the problem. I also tried HTML5 and there is the noise too. Any thoughts what I should do ?
