It was an error on my part, my apologies.
I did a full kernel clean and rebuild, and the error 16 went away.
But the jack detection is still broken.

hdajacksensetest -c 1 -a
Pin 0x0b (Internal Speaker): present = Yes
Pin 0x0c (Not connected): present = No
Pin 0x0d (Not connected): present = No
Pin 0x0e (Not connected): present = No
Pin 0x0f (Not connected): present = Yes
Pin 0x10 (Not connected): present = No
Pin 0x11 (Black Line In, Left side): present = No
Pin 0x12 (Internal Mic, Mobile-In): present = No
Pin 0x13 (Not connected): present = No
Pin 0x18 (Not connected): present = No

Pin 0x0f is still reported as not connected, but correctly detects the
jack if plugged.
If I turn off and on the "HP/Speaker Auto Detect" in alsamixer while
"HP/Speaker" is off, the correct output is detected.
If "HP/Speaker" is on, the behaviour is inconsistent.

Is there a configuration file? Where can I find the metadata "Black Line
In, Left side"?
I don't know if it is related, but pavucontrol detects only the
"speakers" port.
On my previous laptop (with Creative Recon 3Di, another ca0132 card) I
could choose between "speakers and "headphones".
