Linux Audio Issue Clevo P775DM3-G

So I have an odd issue with audio. My 3.5mm/mini toslink combo port is completely non functional. It doesn't work with headphones or toslink. Here's some debug info

and dmesg

Has anyone else gotten this working? If so what steps did you take?

 

Hello there,

I have been looking into a similar issue with the Clevo P751DM2-G and made some progress (I can hear the audio jack detection sound when headphones are plugged in, but no audio signal out, as yet).

You can see my progress here.

If anything else comes up, I'll definitely be in touch.
