  12 The original reporter states: "The Master mixer does not change the
  13 volume from the headphone output (which is affected by the headphone
  14 mixer). Instead it only seems to control the on-board speaker volume.
  15 This confuses PulseAudio greatly as the Master channel is merged into
  16 the volume mix."

  18 Fix this symptom by applying the hp_only quirk for the reporter's SSID.
  19 The fix is applicable to all stable kernels.
