Prodigy 7.1 HiFi on 64-bit systems and QSound
Please be aware that under Windows Vista 64-bit and Windows 7 64-bit the Prodigy
7.1 HiFi driver does not support QSound operation. QSound support is limited
to 32-bit systems only and for usage of QSound functions, especially for computer

own 3D, surround and game sound standards that are available within computer
games that have been optimized for Windows Vista and Windows 7.
