Comment 14 for bug 1201528

you can use hda-jack-sense-test to find out whether the front audio panel headphone and mic have Jack detection or not ?

it is strange that dB min and dBmax of virtual master is different from it slaves (e.g. front, suroound, center, pre and headphone)

state.MID {
 control.1 {
  iface MIXER
  name 'Front Playback Volume'
  value.0 62
  value.1 62
  comment {
   access 'read write'
   type INTEGER
   count 2
   range '0 - 64'
   dbmin -6200
   dbmax 200
   dbvalue.0 0
   dbvalue.1 0
  }
 }

control.39 {
  iface MIXER
  name 'Master Playback Volume'
  value 60
  comment {
   access 'read write'
   type INTEGER
   count 1
   range '0 - 64'
   dbmin -6400
   dbmax 0
   dbvalue.0 -400
  }
 }
