Public bug reported:
The volume of the sound coming out from the headphone jack is always too
loud.
When the GNOME volume applet slider is set to ~50%, I see the following
values on alsamixer:
* Master: 52%
* Headhone: 100%
* PCM: 74%
The sound coming out from the jack is unbearably high.
If I set the slider to ~3% (a setting that produces an high but
acceptable volume) the alsamixer values change to
* Master: 0%
* Headphone: 100%
* PCM: 10%
I found that setting Headphone to ~40% is the only way to get an
acceptable volume when the GNOME volume applet slider is set to ~50%.
The problem now is that these seems to be no way to store that value
permanently, it is always reset to 100% on boot.
So,
* the default values for this device should be adjusted to values that produce
an acceptable volume on the headphone jake.
* the value manually set for the Headphone knob should be restored on boot.
