Hmm, ok, very interesting...

The test code I have (and probably the Vivox SLVoice client which is the
real goal) opens an output stream first and then tries to open the
capture device. It looks like it initializes a "mainloop" for both
streams.  Is that correct behavior or a problem?  I'll do some debugging
around this and see if I can't ferret out a problem.
