Bug description:
  [Impact]
  On one of Lenovo thinkcenter machines we have, there are two microphone jacks
  on the front panel, but only one of them can work after we plug a micrphone in
  them.

  [Fix]
  Because two microphones are located in front panels, the alsa driver will assign
  the same jack name to them, but pulseaudio can't handle two jacks with the same
  name.

  After applying this FIXUP, they will have different mixer name,
  then pulseaudio can handle them correctly.

  
  [Test Case]
  After booting up, plug micrphone into any one of the two audio jacks, the microphone
  works very well.

  [Regression Potential]
  Very low, since this patch is specific to the thinkcenter machine with subsystem id
  0x17aa3138.
