Tried it, but looks to be a different codec to my machine.

so was mine but while testing, I tried:

hda-verb 0x19 SET_PIN_WIDGET_CONTROL 0x25

which worked great so added that to the file, compiled and it works fine now

Thank you for your sincere help!
I used the fix script with hda-verb here and nearly completely solved the problem: https://github.com/jardenliu/ALC298PlugFix
Although there exists small (but acceptable) noise of internal current on my headphone.

You the man!

This looks to have solved the distortion

...and then failed again.

@endoudaiki Can you share the exact steps you are using to get this working?
