RE: [PATCH] ALSA: hda/realtek: Enable headset MIC of Acer AIO with ALC286

Hi,

Don't do this coef setting. It will always assign it for iphone type.
You could dump alsa-info for me with dump coef bit.
Also please plugged headset to dump.

BR,
Kailang

Subject: [PATCH] ALSA: hda/realtek: Enable headset MIC of Acer AIO with ALC286

Some Acer AIO desktops like Veriton Z6860G, Z4860G and Z4660G cannot record sound from headset MIC.  This patch adds the ALC286_FIXUP_ACER_AIO_HEADSET_MIC quirk to fix this issue.
