Set model=auto, try to write all these values to
/sys/class/sound/hwC0D*/user_pin_configs as root, such as
	# echo 0x11 0x18561130 > /sys/class/sound/hwC0D0/user_pin_configs

Then write 1 to /sys/class/sound/hwC0D*/reconfig.  It'll reconfigure
the setup according to the new pin configuration.
The EAPD setting might be still missing, though.
