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
