Upgrade to 6.0 and Onkyo DLNA stops playing

[bethesdaadk]

I upgraded from 5.1 to 6.0 and my ability to play music via the DLNA Interface built into my Onkyo TX NR616 stopped working. It sees the music and the songs in its menu tree, but just can't play the files.

Downgraded back to 5.1 and it works fine.

Any thoughts as to why this might have happened?
