does the user manual or laptop specifovation mention about the support
of conventional Mic with this combo Jack ?
if you using headset (TRRS), headset Mic pin 0x1b was set to vref50
,you may need to disable the Mic pin 0x1b when you using headphone
(TRS) or unpluggef
On some machines, there is a headset jack that can support both
headphone, headsets (of both CTIA and OMTP type) and mic-in.
On other machines, the headset jack supports headphone, headsets
(both CTIA and OMTP), but not mic-in.

Title:
[XPS 12-9Q33, Realtek ALC668, Black Headphone Out, Left] Background
noise or low volume
Status in “alsa-driver” package in Ubuntu:
Incomplete
Bug description:
When listening to sound on my laptop through headphones, there's a
constant background hiss (which disappears only when all sound has
been stopped for a few seconds. power saving I guess).
I also need to turn the volume *way* down to 10% for the sound volume
to be reasonable (it's way too loud otherwise).
