Comment (by j7n):

 If I seek to near the beginning when the click has already played: good
 audio. If I seek to a position later and back to 2 seconds: still a click.

 I have three other examples all from music, but I have to listen again to
 find them. The click is always within a few seconds from the start. Maybe
 it's a peculiarity of the encoder that Apple Music uses.

 An unwanted reset seems to happen between audio blocks, always in the same
 spot.
