Yeah i knew that part..

But anyway thanks, and it already solved.
Somehow i misintrepeted the manual about the snd_tune,frequencie thing.
I thought that a freq. of 1000 would mean the original freq. etc.

But it's like
freq.:10 = 1/10 of original
freq.:100= 1/1 of original
freq.:1000= 1/0.1 of original
