This isn't a paranormal claim, I dunno what caused it but. I was watching a youtube video (while at the same time saving it to my computer with the "Replay Media Catcher" program.). I turned off my electric heater (connected to a differnet power socket), and the sound in my youtube video went out (at the same exact time) (this was accompanied by a popping sound in my headphones) and hasn't come back on yet! Sound in all other programs/apps works fine and when I rewatched the saved youtube video in flvplayer the sound worked. Then I watched another youtube video and the sound was still out! wth?
