Thank you for the continued support and research on the issue.

sudo hda-jack-sense-test -a -c1
Pin 0x12 (Internal Mic): present = No
Pin 0x13 (Not connected): present = No
Pin 0x14 (Internal Speaker): present = No
Pin 0x17 (Not connected): present = No
Pin 0x18 (Black Mic): present = Yes
Pin 0x19 (Not connected): present = No
Pin 0x1a (Not connected): present = No
Pin 0x1d (Not connected): present = No
Pin 0x1e (Not connected): present = No
Pin 0x21 (Black HP Out): present = No

I tried hda-verb as well, working from the scant basic information link. I did not find any manual or other explanation how to use it, so I am not sure tha tmy usage below is correct, nor whether there is a better way to get the values for a whole range of pins other than a loop over a range of value for the pin:

sudo hda-verb /dev/snd/hwC1D0 0x18 GET_PIN_SENSE 0x0
nid = 0x18, verb = 0xf09, param = 0x0
value = 0x80000000

ok, so next step is to pull a kernel source and start fiddling with snd_pci_quirk alc269_fixup_tbl ? I will need help.
0) I did build Intel's kernel when I first got the laptop because the WiFi card was not supported by Ubuntu's Kernel. In the meantime this has been fixed, but the knowledge is still fresh enough in my mind. Can you point me to which Kernel sources you recommend that I get/patch/build?
1) the first two values in snd_pci_quirk_alc269_fixup_tbl seem to be manufacturer / model. How do I identify my machine's manufacturer and model numbers?
2) the second value is just a string, for now it will just be SONY Vaio Pro 13, but I suspect that the issue affects its "cousin" Vaio Pro 11, and probably also the Duo 11 and Duo 13.
3) the third value seem to refer to the fixes listed in hda_fixup alc269_fixups. I can try to use one of the Dell fixups and see if it works, but if none of them does I am at the end of my toolbox. Can you guide me remotely to what I have to do to patch this?

do you recommend I use 'options snd-hda-intel index=1,0' in a file inside /etc/modprobe.d/ ?

Thanks again for keeping the ball rolling. I am not sure when I will be able to follow further up, I have exams coming up in three weeks, but I will try to look at this at least once per weekend and do what I can to help fix this issue.
