I bought my TV and HDMI cable about four-to-five months ago. Everything was fine, but yesterday I noticed that my speakers on my TV are making this airy, wooshing-like sound whenever I play something on my computer while it's hooked up to my TV. My TV doesn't do this when I'm using my WII to watch Netflix, but only when I'm watching something on my computer through my TV. My speakers on my laptop don't make this sound, either - it's only when it's hooked up to my TV and playing things from the laptop. Any ideas on what it might be?
