I've been contacted by several users of Dissonance Voice Chat (a voice chat system for Unity) reporting that starting the microphone takes an extremely long time (over 1 second) if the “Oculus Virtual Audio Device” is in use.
The highlighted line corresponds to calling the Unity Microphone.Start method.
I initially assumed this was a Unity bug and switched to FMOD instead, but that has the same issue. I reported the issue to FMOD and they concluded that the delay is not due to FMOD, but is simply the amount of time that the audio device take to initialise.
It seems like this is a bug in the "Oculus Virtual Audio Device" itself. Something internal is causing it to take huge amounts of time initialising.
