Volume above 100%

[dima1]

Hi.
Please tell me how I can set maximum volume to 100% and restrict using volumes 101-400% ?
By mouse scrolling and volume bar

[p.s.]

I use no english interface but it should be something like this: in the preferences select advanced preferences -> go to interface -> hotkeys -> mousewheel -> select ignore
In the audio preferences you can select the standard volume. I don't know about the volume bar.
