I have SS 4.7 running with apache/tomcat6 on Linux. I can play m4a files without problem logged into SS as admin or guest. If I create a playlist and share it, and try to play the playlist using the share url, m4a files do not play. There are no errors in the log giving any indication that something is amiss. I've tried adding and removing m4a files from the transcode convert from list, but all steps have failed.

hope someone can point me in the right direction.
TIA
