cat /proc/asound/card0/codec#0

if your HDA codec is at address 0 and alsa-driver is 1.0.21 or above

hda - proc - introduce Control: lines to show mixer<->NID assignment

because when your card does not have "Master" volume control but has "Mic"
volume control , it still call filllines_no_master() , the elem of control 0 is
still null

if (mastelem)
             filllines(&mixdev[mixnum], mastelem, captelem, capcontrols);
         else
             if (micelem )
                 filllines_no_master(&mixdev[mixnum], micelem, 1);
