Dear Alsa developers, 

As I reported in the Debian #595661 bug [0], I'm experiencing a "weird" 
behaviour of the snd-hda-intel driver on my Dell Latitude D630:

When the headphone is plugged in, I can't reach all volume levels in it: when 
playing with the "Master" and "Headphone" sliders in alsamixer (all others at 
max), sounds _stops_ being outputted before reaching zero levels (and it's not 
a matter of me not hearing: the sound is still rather loud when it stops).

What I see is that I only get sound when the "sum" of the levels of "Master" 
and "Headphone" is "big enough":

According to my experimental analysis, the minimum "combined levels" where I 
can hear sound are when the sum of the attenuations of "Master" and 
"Headphone" in dB are smaller than 48 dB (see the attached graph for details).

Could this be a hardware limitation ?

Cheers,
