Also, try the patch below without model option.  This should fix the
problem.

Subject: [PATCH] ALSA: hda - Add missing static ADC tables for ALC269 quirks

Some ALC269 quirks define their own .cap_mixer field but without the
static adc_nids[].  This resulted in the mismatch of ADC because ALC269
may have the widget 0x07 for another audio-in, and the auto-parser picks
this up instead.

This patch fixes the problem by adding the static adc_nids[] and co
again to these entries.
