Hello Trond,
could you please tell us what firmware version of the AudioFuse, and AudioFuse Control Center you're using?
current firmware version is 1.1.1 and AFCC version is 1.1.2.
could you also please tell us more about :
the asio settings in your AFCC preferences panel
the situation where you're experiencing dropouts?
the way you connect your audiofuse and used power mode for your laptop ( DC powered, USB? lapotop on battery or power supply?)
at last, there is a bunch of articles on the web, giving good advices about setting up your computer for audio processing,
here's one example :

hope this helps,
cheers,
