5.0 Beta 1 web interface on Mac not working

[flickr4jazz]

I have a relatively new Mac. All OS up to latest updates. Can't seem to play music using a browser on either the server itself or on another Mac on my home network. iSub on my iPad still working fine. When I click on a song, nothing happens. I can nudge the progress bar on the player and the music starts. I have my computer set for auto update of Flash. Could the newest version of Flash player be a problem? Almost all of my music is Apple Lossless.

Same problem here m4a files dont transcode and play properly with the web interface but mp3's play fine

[Exrace]

I am seeing similar issues with m4a files from Above & Beyond- Group Therapy Podcasts.
My server is on x64 2012 windows platform.
Maybe a transcoding issue (my setup set to use this for m4a: ffmpeg -i %s -ab %bk -v 0 -f mp3 -)
Get this error in logs:
