[Hackrf-dev] Performance tuning under virtual box

For reasons that are sad, I have been trying to re-create my previous HackRF set up under virtual box. But if I try to use the ALSA Audio sink under virtual box it goes nuts (in a bad way) stuttering, gui hangs, lots of aUaUaUaUaU in the console. If I put it to a WAV file then go back and play the
