Ok, I think this is roughly where the problem is.  If I open the capture
device only it appears to succeed.  Opening a playback channels fails if
the order is reversed (hanging in the same manner).  So there's some
interaction here between the 2 channels.  I'll do some more debugging
and come back with questions when I have them.  Thanks so much for the
