When I use MAD as the input plugin, the equalister doesn't work, and the visualisation starts behaving strangly: moving when there's silence, etc. Are those all features that are not yet implemented in MAD or did I configure Winamp wrong ?
Do you have the newest MAD? The visualization works fine for me. And I think MAD's meant to be used at default setting on the equalizer, personally, I don't mess with it, it's fine the way it is. Hope that helps.
