Digidesign recommends that you do NOT install the Digidesign WaveDriver if you wish to use Logic Audio with Direct I/O drivers with your Digidesign hardware. If you do install the WaveDriver, you will have to disable it in the Windows Device Manager to avoid multiple -6002 or -6031 errors when you launch Logic Audio. You can disable Direct I/O and use the "PC AV" driver with the WaveDriver for 2-channel I/O using your Digidesign hardware - although this configuration may be unstable on some systems.
