Pro Audio Support

Q:
My PreSonus Firewire hardware is not working on my PC.
 
A:
Check you chipsets. According to PreSonus, laptops with the ATI Mobility Radeon 9000/9100 IGP chipset have shown consistent problems with pops/clicks on playback. You can check for this chipset in the Device Manager/Display Adapters. We strongly recommend that you do not get a system with this chipset, as there is not currently a workaround for this incompatibility.
