It is very hard to set the right volume when the volume bar won't change the sound "live". I need to move it with the mouse, release the mouse button, listen if the volume is right. If not i have to do the same thing again and again until i find the right volume level. It would be great if it worked as a real volume button do.
You write "Fine-grained control: 0 % - 600 %" but i can only move it in step of 10.
