musicpd (mpd) doesn't stream aac

Hi folks, built current musicpd 0.13.2 from ports with aac/mp4 support, connect to an aac stream, and musicpd just sits there, like its playing, but nothing actually plays. Other streams, ogg/mp3, play fine. Is there some kind of limitation to aacc/mp4/m4a to local files only and not streams?
