What is the expected behavior?

What went wrong?
The kFIFOSize in Blink's AudioDestination.cpp probably needs to be bigger since some OSes allow buffer sizes of 8192 via latencyHint now, or else we need to do some validation of the latencyHint 'exact' size before passing it to CreateAudioDevice(). Clamping may be tricky though as the buffer size is dependent on the sample rate for some platforms and we're passing in a time value and not a buffer size in the latencyHint.
