Of course I've already updated everything but the audio still really sucks!
And yes I confirm that the only thing "working" (= you can actually hear the difference) is the button ON at bottom to activate Sonic Audio, everything else: Reverb, EQ, Bass amp,voice clarity etc. have no audible effect at all... and sounds too bad.

Sonic Studio II sliders/options have an audible effect only playing the test sound (Audio Player, "Lettore audio" in the pics) you can see in the bottom left. It's not used system wide or in-game. I think it's a serious bug, that's why sound is so dull... On/off makes a difference though, but the others features are ignored outside of this panel.
