[alsa-devel] [PATCH 1/4] ALSA: hda/realtek: ALC286 mic and headset-mode fixups for Acer Aspire U27-880

[Kailang]

Hi Jian Hong,

Please also try to change model to ALC269_FIXUP_HEADSET_MODE_NO_HP_MIC.

+		.chain_id = ALC269_FIXUP_HEADSET_MIC  ==> change to  ALC269_FIXUP_HEADSET_MODE_NO_HP_MIC

BR,
Kailang

Subject: [PATCH 1/4] ALSA: hda/realtek: ALC286 mic and headset-mode fixups for Acer Aspire U27-880

From: Chris Chiu <chiu at endlessm.com>

Acer Aspire U27-880(AIO) with ALC286 codec can not detect headset mic and internal mic not working either. It needs the similar quirk like Sony laptops to fix headphone jack sensing and enables use of the internal microphone.

Unfortunately jack sensing for the headset mic is still not working.
