DVR Playback on Apple TV, no sound (fine via Web or iPhone and iPad)

I just got a HDHomerun Connect and configured it. The first recording looks like nice quality but when I try to play Plex from Apple TV, there is no sound. I tried the same program via the web interface from another computer, from another iPad (Plex app) and iPhone and they all work fine and have sound. Could that be a setting or just a bug to be worked out?
Thanks! Really like the DVR and functions of Plex, looking forward to Live TV too!

Nevermind! I hadn’t changed the Update to Plex Pass and was a number of updates behind. When I was able to get the current version it’s working. Woops.
