We've been able to reproduce it. There does seem to be an issue with Exoplayer misreporting the audio. We've tried the older version of AVPro, and while it plays fine the first time, subsequent plays are slow and choppy. We'll have to see if there is anything that we can do about this. In the mean while, I suggest using System Direct to play these videos :)
