Comment 9 for bug 978880

Might have to restart after doing that, btw. If this doesn't work for you, open the "Sound" program from the launcher, and see which profiles are being used when you plug in headphones and then take them back out again. Then do the same steps above, but using the profiles you see in the "Sound" program.

For example, I edited the "Element Speaker" section in the "Headphone" profile because when I leave out the headphones, the Sound program displays my profile as "Speaker," and when I plug them in, as "Headphone."

Good luck.
