I'd thought the same thing initially but it happens whether Bluetooth is connected or not. That particular file always plays for about 10 minutes at a time so it makes it easier to reproduce the problem but I was playing at 400% speed for brevity - it stops in the same way at normal speed. The logs are intentionally cut down in order to keep only relevant data. The same file plays fine on my S5 and other videos and audio do the same thing though less consistently.
@lumix14 has problems with almost every file.
If you are using a Bluetooth device, can you check again with internal speaker?
