The Advantech MICA-071 tablet deviates from the defaults for a non CR Bay Trail based tablet in several ways:
- It uses an analog MIC on IN3 rather then using DMIC1
- It only has 1 speaker
- It needs the OVCD current threshold to be set to 1500uA instead of the default 2000uA to reliable differentiate between headphones vs headsets
Add a quirk with these settings for this tablet.
