So I assume finally musicbee is not ASIO compatible?
ASIO was invented and designed for studio and recording purposes.
There is no good reason whatsoever that any music player should, or even could be 100% compatible or compliant with everything that ASIO entails.

Also, it will depend on the features and quality of the drivers that the manufacturer of your audio device makes available.
And those are often, well, crappy.
