So I'm currently using Ubuntu 13.04 on a Lenovo Thinkpad R61i laptop and the problem I have is that the actual sound volume doesn't grow linearly with the change of the volume slider position: in the range from 0% to 75% it grows very slowly, but in the range from 75% to 100% does so very rapidly - so that a small change of the slider's position corresponds to an unproportionally large change in volume.

What might be the case and how can I fix it? Used to work well on Ubuntu 11.*

Ubuntu 13.04 has reached end of life. You should upgrade to 13.10 or 14.04 LTS (or downgrade to 12.04 LTS). – To Do May 1 '14 at 13:26

This question may be relevant for recent Ubuntu releases too. – Andrea Corbellini May 4 '14 at 19:40

If the volume slider seems off, you may try adjusting the volume in alsamixer first (should be set to middle for volume I believe).

In terminal type


and then use your arrow keys to adjust the volume that way, check to be sure your volume slider isn't already all the way at the top, throwing things off. I try to get mine to be around even with my volume slider and then adjust volume a few times to make sure everything works correctly.
