Sometimes when listening music with headphones the audio stops from them, probably always when the song changes. If speaker volume is non-zero the music is heard from the speaker, if zero then it's not heard.
Music changes back to headphones when stoping and starting the song again, sometimes couple of times is needed. I'm using Google Music and have no idea if the problem is in it, or in Android system. And sometimes audios are routed to speaker when starting another app that tries to play sounds.
It's an annoying bug.
