When I open up the Playback Engine window and open the drop-down menu for the output device, my headset (which is what I use as my default output device) doesn't show up. My headset microphone (which I use as my default input device) doesn't show up under input devices either.
This is a big problem, since I can't hear any sound from the program. I can't use the output device that shows up either, since that is for a TV I had plugged to my computer once.
I use Windows 10 and Pro Tools First 12.8
