   4 Subject: ALSA: hda - Fix mute sound with STAC9227/9228 codecs
   5 Patch-mainline:
   6 References: bnc#546006
   7
   8 On FSC laptops, the sound gets muted gradually when the volume is chnaged.
   9 This is due to the wrong volume-knob widget setup.  The delta bit (bit 7)
  10 shouldn't be set for these devices.
  11
  12 This patch adds a new quirk to set the value 0x7f to the widget 0x24
  13 instead of 0xff.
