I just got back from a vacation and in the time I was gone there was a power outage and my airport express reset itself. I have since done a full factory reset, updated the firmware etc. But now when I am using airtunes the music only comes out of the left speaker. If I plug the speakers directly into my G4 iBook (via the headphone jack) it comes out of both. Is there somewhere that I can reset the balance? Or is it possible that the output jack on the Airport itself got fried?
