--- Comment #13 from Takashi Iwai ---
Well, let me repeat again a few points you are still missing:
- The previous behavior was buggy. It was incorrect. So, the previous
behavior cannot be used as a reference.
- You have to compare with *another* machine with another sound chip as a
proper refernce.
When comparing, better to use the headphone output. Raise Headphone and PCM
volume to 0dB, and adjust Master volume in the target dB. Suppose that the
onboard chip is assigned to card 0,
% amixer -c0 set PCM 0dB unmute
% amixer -c0 set Headphone 0dB unmute
and change Master volume, e.g. targetting to -12dB,
% amixer -c0 -- set Master -12dB
Then play the same material on both machines and compare the loudness.
