Yes there is a difference:
With mic plugged I get the following in lines 161 to 172 of codec#0:
------------------------------------------------------------
Node 0x1d [Pin Complex] wcaps 0x400985: Stereo Amp-Out R/L
Amp-Out caps: ofs=0x1f, nsteps=0x1f, stepsize=0x05, mute=1
Amp-Out vals: [0x80 0x80]
Pincap 0x081737: IN OUT Detect Trigger ImpSense
Vref caps: HIZ 50 GRD 80
Pin Default 0x01019015: [Jack] Line Out at Ext Rear
Conn = 1/8, Color = Pink
DefAssociation = 0x1, Sequence = 0x5
Pin-ctls: 0x00: VREF_HIZ
Unsolicited: tag=00, enabled=0

This patch does not work. The external mic is always disabled and there are
not differences in the codec# proc files.
