Channel mode is created when there are three or more jacks at same location

Use hdajackretask to change location of HP and Mic from Ext Rear to Ext
Front

Advanced override and set as boot default

http://git.alsa-project.org/?p=alsa-tools.git;a=tree;f=hdajacksensetest;hb=HEAD

Use hdajacksensetest -a to verify line out support jack detect

clear MISC = NO_PRESENCE bit 8 of pin default of Line out by hdajackretask

Pin Default 0x01010050: [Jack] Line Out at Ext Rear
    Conn = 1/8, Color = Unknown
    DefAssociation = 0x5, Sequence = 0x0


Most likely need vendor coefficient to support mono  mic of apple earphones
