I'm running Ubuntu 9.04 and when listening to music I usually just turn the volume up and down with the buttons on my PC. Tonight however, I found out that my headphones I've had for 3 years broke (only the right speaker was working because of a short), so I open volume control and adjusted it so that it would send all sound to the right speaker.
Now whenever I play music without my headphones and try to change the volume with the buttons on my computer it does absolutely nothing. Is there a way I can reset the default values for the volume control?
