Reply to A Problem I Discovered with the S4 at my last gig...Anyone else have this?

Me and a friend of mine were playing a set on my S4, and we both had our own pairs of headphones. So while unplugging one pair and plugging another pair of headphones into the S4, the music just stopped. I quit Traktor and the same thing happened. Thankfully this occurred during setup so we the music didn't stop during the gig.

Anyone else encounter this problem? I have the Guitar Center extended warranty, so worst possible outcome is that they pay for this.
