Hello Robert,
Thank you for the clarification.
Unfortunately, according to our
Support Policy, we cannot assist you in resolving issues with third-party software. The reason the person on the call cannot hear you, perhaps, as your local mic input is being transferred to the remote machine and is played there as playback audio, not a microphone input.
I tried voice chat but that does not seem to allow me to have full control of the computer, which I need. After starting voice chat, I clicked the full control button in the options box, but I am not sure of that still leaves me in voice chat, or if has switched to full control outside of voice chat.
Actually, you should be able to invoke a few different connection modes windows at the same time. I've just tried connecting to a remote Host via the Voice and Video chat mode along with the Full Control connection mode and it worked as expected - both connection modes work properly and do not interfere with each other even if you have the sound capture enabled in the Full Control mode.
Hope that helps.
