[alsa-devel] [ALC668]: Asus N751JK - Incorrect default pin assignment for external base speaker and external microphone not working

[Arthur Borsboom]

The jack test gives

Without external speaker plugged in:

Pin 0x12 (Internal Mic): present = No
Pin 0x14 (Internal Speaker): present = No
Pin 0x15 (Black Headphone, Left side): present = No
Pin 0x16 (Not connected): present = No
Pin 0x18 (Not connected): present = No
Pin 0x19 (Not connected): present = No
Pin 0x1a (Not connected): present = No
Pin 0x1b (Not connected): present = No
Pin 0x1d (Not connected): present = No
Pin 0x1e (Not connected): present = No
Pin 0x1f (Not connected): present = No

With external speaker plugged in:

Pin 0x12 (Internal Mic): present = No
Pin 0x14 (Internal Speaker): present = No
Pin 0x15 (Black Headphone, Left side): present = No
Pin 0x16 (Not connected): present = No
Pin 0x18 (Not connected): present = No
Pin 0x19 (Not connected): present = No
Pin 0x1a (Not connected): present = Yes
Pin 0x1b (Not connected): present = No
Pin 0x1d (Not connected): present = No
Pin 0x1e (Not connected): present = No
Pin 0x1f (Not connected): present = No

For the other parts, I lack the experience.
I have just set up a test environment, so I can recompile and test kernels
without breaking my main system.

If you have any patches to suggest and test (for the external speaker and
the auto switch of headset), I am all ears.
If not, I will try to dig in it myself.
