I also observed the same issue. For some reason, 1 is not the maximal volume as stated here: https://github.com/Sascha-L/WPF-MediaKit/blob/8db992125d11abc400d237ff9dfeba3f32afd872/Source/DirectShow/MediaPlayers/BaseClasses.cs#L377. I haven't had any research on the root cause yet.

I observed the same problem. It seems the volume while playing music or video is not linearly proportional to the volume bar's position.

Looks like the DirectShow interface uses a logarithmic scale for volume. See https://docs.microsoft.com/en-us/previous-versions/windows/embedded/ms939532(v=msdn.10)
