So when I fly in P3D I usually use headphones. I didn't have a problem until recently where it seems that if I don't have my headphone plugged in before I start the sim they won't be  recognized, so I might be missing some sounds in 3rd party aircraft.  It seemed like before I could plug in my headphones after I loaded everything up and still get sound.

So, any suggestions on what I should check.? I just have the generic Real Tek audio device and have a port on the front of the computer where I plug the headphones in.

 

Thanks

HIt alt+enter to take it out of full screen then check to see if a dialog box is popping up in the back ground asking you to confirm the head phones you plugged in. Then click don't ask again if you have the option.

I have the same problem with Bluetooth headphones. If the aren’t connected before I start P3D I can’t see them in the audio options, I need to restart  and  connect headphones first. Then, if I disconnect them on a long flight (to go to bed lol) they crash the sim.
