Thanks for the advice Rafa. In fact, this advice helps to solve the
problem with the speed curve. Now it works fine :-) It is a clue for
fixing this bug.

It would certainly not be wrong to have a time plugin (for audio and
video) that can be used as an alternative to the speed curve. I am a fan
of the speed curve, but sometimes such a time plugin would not be wrong
in certain situations.
I will attach this post to the ticket.
