So, I'm loving everything about the 8.1 update, except I keep have issues with my headphones. The audio keeps getting cut from the right headphone that I'm using and the only thing that fixes it is to power off the phone completely and turn it back in. It's extremely annoying. I'm using a Lumia 920 and I've never had this problem before 8.1. Should I do a factory restore maybe? Would that erase 8.1?
