Comment 3 for bug 1509921

ports:
  analog-input: Analog Input (priority 10000, latency offset 0 usec, available: unknown)
   properties:

  analog-input-microphone: Microphone (priority 8700, latency offset 0 usec, available: no)
   properties:
    device.icon_name = "audio-input-microphone"
  analog-input-linein: Line In (priority 8100, latency offset 0 usec, available: no)
   properties:

 active port: <analog-input>

it is strange that analog input is the active port when rear mic and line in are not plugged
