Hey guys, recently I've noticed a sort of hissing sound coming from my computer speaker. It appears when I'm playing a game (quiet when loading but as soon as it hits menu it's very audible) and changes pitch/rhythm. It also appears when I'm using Smooth Scrolling in Opera or Firefox.
Have noticed that too on my old computer. Exactly as mentioned, moving windows around and graphics intensive gaming. Did not find a solution back then. Bumping this thread a bit, and also to get a notification if a solution is found.
