Troubleshooting 5.1
Known Incompatible Hardware
• ATI RADEON 9000/9001 IGP video chipset.
Symptoms are consistent click and pops during
audio playback. This video chipset is only found
in PC laptops and is entirely integrated as the
computer’s only video controller. PreSonus
strongly recommends that users do not purchase
a system with this chipset as there is currently no
workaround for this incompatibility.
• USB/FireWire and s400/s800 combo cards.
Symptoms usually include no audio recording/
playback, even though the device will install and
sync, and erratic audio performance. Rarely, combo
cards will prevent the device from installing or
achieving a stable sync. We recommend FireWire
cards that have S400 FireWire connections only.
• FireWire cards with NEC chipsets. Symptoms
include installation issues, erratic audio, and static
and noise.
• Motherboards with nForce4 chipsets. Symptoms
include reduced to very poor performance,
especially if using the onboard FireWire
connection. Installing a PCIe (not PCI) FW400-
only card with an approved chipset is a known
workaround but might not allow full performance.
