nexus 5 + headphones stops playing

Great app! Like it much better than tune in :)
I am seeing one problem though. I typically start playing a stream via the built-in speaker then plug in headphones after 10 min or so. Invariably this causes the stream to stop playing indicating that it's re-buffering. It never reaches 100% and the only way to continue playing is to hit stop then play again. 
This is only an issue on my new nexus 5. This did not happen on my old galaxy s2.  On my old phone I'd plug in the headphones and the stream would just seamlessly transition to playing through them. 
Thanks!
