Volume mouse wheel issue after delaying subtitles

[user0000]

Bonjour,

Lorsque l'on retarde les sous-titres avec la touche par défaut "G" au delà de 2000 ms le défilement du volume avec la molette de la souris n'est plus fluide par rapport au fonctionnement habituel.

Delay between tracks has to stay within reasonable limits, otherwise buffering stops functioning. This is mostly intended for delay of a few hundred of milliseconds.

I am sorry if my explanation wasn't very clear.

When you change the sound volume of a video with the mouse wheel, changing the sound volume is fast.
But if you have to correct a badly synchronized subtitle track by using the shortcut key "g", once you reach 2000 ms when if you want to increase or decrease the volume of the video the change is no longer completely smooth as before.
I mean the audio level not skip the video
