We have seen instances of our WNIP audio driver not starting properly with Windows. In these cases, you can go to the Windows | Services applet and find that the driver isn't running. Starting the driver resolves the issue.
The primary reason that the driver might not start automatically with Windows is that the bootup process is happening so fast that when the driver tries to learn the MAC address of the NIC it's configured to use, that information isn't yet available because the networking service isn't fully up and running yet. This could be due to the use of a solid-state drive as boot device, as they load startup modules very quickly. Or there could be other services that need to run before the networking runs.

Once you're there, scroll down to the WheatNet IP Transport Service. Right-click on the Wheatnet IP Transport Service and select Properties. Set the driver's Startup Type to Automatic (Delayed Start):
