I think i've got something!
Winamp -> HQsoftproc 16/48 -> Asio Output -> Asio4All -> KX Fxbus 0/1 -> KX Asio 0/1 -> Console -> KX Fxbus 2/3 -> Jack
Like this Console is set to use the KX device and kmixer is bypassed.
At first it was very noisy, but at soon that I turned Hardware buffer on in Asio4all, things get right!
