I am using a Plantronics wireless USB headset microphone. Camtasia 8 Audio Setup recognizes the device in the Audio Device menu (image below) but it does not register a signal. When I try the setup record test, it doesn't detect a signal. Weird that it recognizes the device but can't seem to get the signal. Does anyone have advice for this to work? I really would like to use this small form factor headset for recording from webcam but obviously I need the mic to work. Thank you.
