    ALSA: hda/realtek - Improve the headset mic for Acer Aspire laptops · 9cb40eb1
    Hui Wang authored
    We met another Acer Aspire laptop which has the problem on the
    headset-mic, the Pin 0x19 is not set the corret configuration for a
    mic and the pin presence can't be detected too after plugging a
    headset. Kailang suggested that we should set the coeff to enable the
    mic and apply the ALC269_FIXUP_LIFEBOOK_EXTMIC. After doing that,
    both headset-mic presence and headset-mic work well.
    
    The existing ALC255_FIXUP_ACER_MIC_NO_PRESENCE set the headset-mic
    jack to be a phantom jack. Now since the jack can support presence
    unsol event, let us imporve it to set the jack to be a normal jack.
