Public bug reported:
[SRU Justification]
[Impact]
The Dell Latitude 5430 series with Realtek audio codec ALC3254 fail to detect
the headphone microphone and thus unable to do recording.
[Fix]
The realtek audio quirk ALC269_FIXUP_DELL4_MIC_NO_PRESENCE is required since
the NID used for headphone microphone should be 0x1b instead of 0x1a, which is
used for former ALC225/295 variants.
[Test Case]
1. Plug in the headphone microphone on the particular Dell Latitude 5430 laptop
2. Make sure it's detected in Audio Settings. (pulseaudio)
3. Record the sound via the headphone microphone and check the recorded content.
[Where problems could occur]
No. Since the audio quirk only affect the machine with particular subsystem ID.
