> The Dell Latitude 5430 with Realtek audio codec ALC3254 fail to detect the headphone microphone and thus unable to record audio.
> 
> [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 problematic 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 fixup is only applied on the machine with particular subsystem ID.
> 
> [Other Info]
> This is not yet available in mainline kernel but in linux-next, and need to be applied after SRU lp:2000909
