Research direction
Start by reproducing the issue with mpv --no-config and out_jump_40s.ts, then inspect the linked mpv.log while comparing playback with ffplay. Trace how mpv handles the discontinuous timestamps in the sample; done means the audio and video remain synchronized after the timestamp jump.
