What brand/model is your laptop? I use Hypersonic 2 in a regular basis in BiaB since version 2006, it work flawless and sound really cool, however I know some not so new HP laptop with Athlon processors tend to behave wierdly with BiaB,VSTi and some audio cards, in my case I got problems with a Pavillion model from year 2006 and my M-Audio Black Box USB, it was near to impossible get it working, Hypersonic 2 and any VST1 just turn muted after few bars. At start I think the cause of this was my Steinberg USB protection key being rejected but I did change the usb port and all was fine, but audio still muted. With my new Pavilion 2000 all is working perfect under Windows XP SP3 and all my audio interfaces. Maybe this can be so basic, but remember set your Hypersonic 2 in GM mode and Program Change ON at SETUP menu window, because sometimes Hypersonic 2 run by default without instruments loaded except in ch.1 (not used in BiaB by default) . Good luck
