Mixvibes U-Mix 44 & New macbook pro

Hello there,
I just bought a new macbook pro and the mixvibes U-Mix 44 does not work anymore. Under audiosettings on the mac it chooses the U-Mix 44 for audio Output but there is no sound.
Perhaps i need to download a diver but i cannot find it anywhere on the web.
The U-Mix 44 is still working with my Old macbook.
Any help?
Cheers
