** Description changed:

- Steps:
- 1. Installed system and log in.
- 2. Plug microphone into microphone jack
- 3. Try to record voice from mic
- 4. Unplug in microphone, plug a headset into headset jack
- 5. Try to record voice from mic of headset.
+ [Impact]
+ On the machine of Lenovo M715, there are 2 audio jacks on the front panel,
+ one of them is microphone jack. When we plug a micrphone into it, the system
+ can't detect this microphone and can't record sound via this microphone too.
  
- Actual result:
- Nothing can be recorded by jacks.
+ 
+ [Fix]
+ Apply the quirk of ALC294_FIXUP_LENOVO_MIC_LOCATION, the alsa driver will
+ assign a different name to this audio jack, then pulseaudio can handle this
+ jack and everything works well.
+ 
+ 
+ [Test Case]
+ plug a microphone to this jack and record sound, system can detect the
+ microphone and can record sound.
+ 
+ [Regression Potential]
+ Very low, this pin configuration is specific to the machine of
+ M715 so far, will not affect other machines.
