I run Prepar3D on my main computer and a second desktop that has many add ons that link to it through simconnect.  The ATC program I use is pilot2atc.

Anyways,, I had it working at one time, where I was getting audio FROM BOTH my main computer AND second computer TO my usb wireless headset.  So, the microphone is also on my usb headset as well.  It all worked awesome.

But, I have never been able to get it back that way.  It seems the audio output from my second system does not want to send it to the usb headset again   I am sure I am missing something simple, but I have tried and read and have just got more brain tired   I mean, I have set this program up many times.  Any ideas of what step I might have overlooked?!
