Nokia Lumia :: Music Does Not Stop When Unpluging?

when I unplug my headphones music (in my case podcast) continues to play when I unplug my headphones. The audio comes out the built in speakers at the bottom of the phone. Other times, I get a short (less than 1 second) bit of sound out of the bottom built in speakers. This is really annoying to my wife who wakes up from the sound when I unplug my headphones in bed after she has gone to sleep. I expect no sound out of the peakers when I unplug the headset. Seems like a timing issue and a surprise removal can be hard to deal with, but you got it right with the 900.I used to have that phone before the 920 and it never had that issue.
