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, -- OdyX [0] http://bugs.debian.org/595661
