Hello Everyone,

I take a class through Blackboard Collaborate and teach a class where I use Zoom and Webex Meetings. I have external speakers for playback and have tried to use 1) Youse headset for the microphone,  2) a lapel mic for the microphone, 3) Logitech H800 for the microphone, and 4) headset adapter splitter.   My computer is a workstation Precision 3630.  This is my experience:

1. When I plug in the Logitech H800, I have no problems because it is USB.
2. When I plug in the Youse headset, I want to use the microphone only and external speakers.  I use a splitter to use only the microphone and a dialog box with the following appears:  
   1. Which device did you plug in?
      Headphones/Headset
        over-ear  on-ear   earbuds
      External Speakers      External Speakers Medium

         I don’t know what to select.  What is the difference between headphones and headset?  I have
         selected everything and nothing works.

     3.  When I connect the lapel mic, I don’t know what to select again because it is not a headphone nor
         headset.  Again, I have tried selecting different things and nothing works.

        What is the difference between Stereo Mix Realtek and Jack Mix Realtek?

I really appreciate help because this is frustrating not to get these other devices to work.  Thanks.
