Reply to S2 Issue: Headphone emitting highpitch buzz/not working

Hopefully someone might know what is going on here. Google doesn't seem to be coming up with anything. I went to plug my headphones in my S2 last evening and when I turned it on, there was a loud high-pitched buzz coming out of my headphones. Cueing a song didn't play any sound through the headphones either rendering headphone cueing unusable. However, turning down the cue volume would bring down the volume of the buzz. The headphones work fine in other devices. Has anyone heard of this happening before? I hope this controller isn't busted
