This different headset mode support is likely unrelated to your problem.
And they don't cover your codec (ALC286), so you would need another set
of verbs too, things that only Realtek knows.

An important distinction is here: to they work in Windows without
specific Realtek drivers installed, or do you require Realtek's Windows
drivers for this support?
Second, to do some actual triaging. I see you have been running
hda-jack-sense-test. Could you run it all three scenarios:
1) nothing connected
2) headphone (without mic) connected
3) headset (heaphone + mic combo) connected
...and submit the result? In ideal circumstances, 0x21 should report
"Yes" in scenario 2 and 3, and 0x18 should only report yes in scenario
3. If this is not the result you get, try using hda-jack-retask to turn
off the jack detection: in Ubuntu 13.10 just install the alsa-tools-gui
package (no need to use my ppa). Click "advanced override", find pins
0x18 or 0x21, change "jack detection" from "yes" to "no" and click
apply. Now you should be able to manually choose between internal and
external microphone, as well as between headphones as speakers. See if

I'm afraid Sony is not a company that actively supports Linux for the
desktop machines, sorry. Canonical, which seems to have the most
contracts for preloading Linux these days, has a list of certified
hardware here: http://www.ubuntu.com/certification/
