For some reason when I plug my headphones into the front audio jack in my computer the sound output of running applications is not moved to my headphones. The audio remains with my speakers. The converse is true too - unplugging my headphones will not transfer audio output that is on my headphones to my speakers. I had run into this problem when I was originally setting up my computer and I had been able to fix it. All I had to do is set my headphones to my default sound output and the computer would switch everything when I plugged them in. My headphones are still the default audio source, but for some reason the switching no longer works. Does anyone know why?
