Playing music off my external hard drive, i'll get one or two songs into an album and a track will get caught in a loop (I've obviously checked that repeat is off).
See attached example, the time elapsed will read 4:29 / 3:43 (track has been playing for 4min 29 sec out of 3min43sec total track time. You can hear the song get about halfway through then skip back to the start.
This is the first time I've started using Plex to play music, but obviously this makes using it as my principal player unworkable.
The error doesn't happen on every track, but has occurred at some point in each of the three albums I've played (maybe track one, maybe kicking in at track 3-4).
I'm on El Capitan with Plex Pass, using Safari as my browser. Using a MacBook Pro (15-inch, Mid 2010). Log files are attached.
