Thank you so much! Changing audio hardware choices under preferences seems to work in Windows 7. It said my Logitech wireless headset (my preferred choice to edit) was not working, but it offered me another choice for Logitech wireless head set, so I chose that. I got sound! ... out of my computer’s built in speakers. Hm. I chose my computer’s speakers as the default hardware – and got sound in my headset. My takeaway is to ignore the name of the audio hardware device and just choose the device that works, regardless of the name. The same might go for the microphone, but in this case, choosing my wireless microphone made my wireless microphone work. Go figure. Thank you again for your quick and clear answer. I was really stressed out. This information really should be in the Adobe documentation troubleshooting section.
