I just finished installing 12.04 on my laptop and everything works fine but the sound. If you look at the sound meter at 75%, it's totally off. And at the 100%, it's as loud as it can be. There is no sound at 0% to 75%.

If you go into alsamixer, and press the volume buttons, you can see it makes jumps of about 20% every time the volume button is pressed until it reaches zero.

Does anyone know how to adjust this?
