Help - W500, Vista x64, SRS Audio Sandbox is not working

[K-a-M-u-Z-u]

Hi.
got my new Thinkpad W500, installed Vista X64 and everything is updated and working fine.

on my old machine(R40+vista) i had SRS Audio Sandbox running to enhance the audio(and it worked great).the same with my MSI Wind U100(vista).
but on my W500, there is no sound at all.i have the 64bit version of the SRS 1.9, it was installed right, and i have restarted windows.when i play music i can see the audio level meter working as it was playing sound, but no audio from the speakers.i tried changing the Hardware host and restart the playback, but still, no audio.
the card is conexant high definition smartaudio 221 and it works fine when i TEST it in the Vista's Mixer.
does anyone know what could be the problem?
thnkx.
