I hope that play-speed can be changed by mouse scroll while
playing audio file.

I have set default play-speed to "-speed 1.5" to watch video quickly
to save time. You can change play-speed by mouse scroll on the
video window while playing video if you want to play slowly.

In the case you listen music, play-speed shall be 1.0 basically.
But play-speed can't be changed by mouse scroll while playing audio.
If you want to change, you need to click menu several times.
It takes time.

Preferences -> Interface, turn off the option "hide the video window when playing audio files". This way you can use the mouse wheel to change the speed over the video window.

I also noticed that the speed can be changed when the mouse is over the seek bar.

Thank you. This inquiry is solved.
