I'm setting up a friend's HP Presario (quite old) laptop with Ubuntu 12.04 which used to work fine in 11.10. However, the volume is completely silent until it is turned up to about 3/4. Past this point, it makes giant leaps all the way up to 100% when volume is on full.

Alsamixer, however, shows this perfectly. The 'master' bar stays at zero until the normal volume setting is past 3/4, so it's measuring actual volume perfectly. This suggests that it's a problem with Ubuntu's volume control.

EDIT - on the sound settings labelled volume slider (at the bottom), the volume seems to be zero at the 'unamplified' point (75% across the bar) and 100% at the '100%' point.

hey :) some people seem to solve this one: – user82955 Aug 12 '12 at 19:10

I have had the same problem. I fixed this by going to configuration settings -> sound -> output i chose headphone + amplifier, on the tab hardware i selected analoge output profile instead of analog stereo duplex. With these settings, it's less out of phase.

Ubuntu 12.04 doesn't have a hardware tab, the settings have merged and there are fewer options now. – Sman789 May 18 '12 at 13:28
