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,
