Video Conferencing Script - Logitech Zoom w/ Mic

Hi all,

  I'm following the excellent example code set forth in "Learning FMS3" from Chapter 5.  It works quite well, except for one thing: If I execute the script on a machine that has, say, a Logitech Zoom that has both a camera and a mic, it seems like it can either do one or the other, but not both.  E.g. if I set the mic to be something else in Windows Control Panel, the video is just fine, but no audio is broadcast.  However, if I set the mic to be the built-in Logitech Zoom's, the audio works but no picture is broadcast.  Is there any way around this?  I reckon it's because a device context or handle is given to the device for one purpose, and the next time it tries to use it for another function, it likely overtakes it for single usage.

  Any ideas?  Thanks in advance!
