I have a dell latitude e6420 laptop. The problem is I have to raise volume up to 30% to hear something, but with windows 7, only 1% to barely hear, which is good, but with ubuntu even 100% is low compared to windows. With ubuntu 12.04 the following link fixes it (ignore_dB=1):
I had ubuntu 12.04 until now, I want to upgrade. But, ubuntu 14.10 opensuse 13.2, fedora 21, the problem persists and the fix makes it worse (at least on live). Elementary os luna has no issue on this, as well as fedora 15. Thanks. Edit: The thing that bugs me, is that I have to raise volume around 30% to hear the minimum. I already have it set to pass 100%. With 12.04 currently installed, the previous link fixes it for good. But with newer distributions (14.04), which I would like to install, the problem persists, and the fix worsens it, as well as other current distros. This issue appears to be fixed on several websites. Is there a way I could have the pulseaudio from 12.04 on 14.04? Audio card IDT92HD90xx.
