I'm trying to get my Logitech USB headset/microphone fully up and running on my new computer.  I had been using it purely as a USB microphone for FS2Crew for a long time on my old computer (no playback, using main speakers).  However, I've worked on getting back up on VATSIM and really want the controller to come through the headset to improve my ability to understand them clearly.  So...

 

The Logitech set shows up under both playback and recording devices.  It is the default recording device and works just fine for FS2Crew and transmitting on VATSIM.

 

It shows up as a device in playback, but I do not hear anything.  I see the Windows "levels" showing green "sound" bars in playback, but hear nothing.

 

I am suspecting the USB headset may be broken, but was hoping others might have some troubleshooting advice before I just buy a new one.  Thanks for any help.

Have you set Voice to go to the headset in the FSX sound options, that's the only thing I can think of. Unless you have to set the sound device in the VATSIM software somewhere. Sorry that is all I can suggest, not being a VATSIM or IVAO user I don't really know how they work.
