So my sound was working just fine on Windows 7 until I decided to have a video chat with my friend over Live Messenger. I was simultaneously listening to music and video chatting at one point until I decided to pause my iTunes. Then when we were done chatting I went back to play iTunes and now the music wont even begin to play. I cannot hear any audio on Youtube or anything either and the video actually stops playing after a couple seconds on youtube too.
I have a Dell XPS 1530 if that helps any. Sigmatel Audio is what I believe runs my audio.
EDIT - Nevermind... I restarted my computer and all is well again. I guess I freaked out and should have waited to post this
