I use my iPad 3 with an alarm clock app to wake me up every morning. I put it on the dock, set the alarm, and go to sleep. Half the time since I've updated to iOS6, the alarm is going off, but no sound is coming out. I've noticed this happen when I pick it up off the dock once in a while and want to watch a video... no sound. So it's not just the alarm clock app. It's like the whole audio software system is dead. When this happens, I need to restart the iPad to get sound back but the audio will stop working at some random time later, making my iPad useless as an alarm clock. It worked flawlessly before iOS6. WTF! Anyone else having this issue?
