For ASIO devices, the above error message may appear, usually because of any of the following reasons:
-The device is already in use in DirectSound or WASAPI mode, either by mAirList or another applications. Most ASIO sound- cards cannot be used in ASIO and DirectSound/WASAPI mode simultaneously.
The sound card has been removed from the computer, but the drivers are still present in the system.
So do I and funnily enough I started to get this message today. Turned out a new Audio driver related to some Ham Radio stuff. FAQ told me to set ignore and I did. Voila.
