The GNOME settings sound entry list is empty. Speaker sound is working properly. When hooking a microphone enabled headphone on the jack plug, the headphones mic is then detected, but there is now no sound output on the headphone. I've been looking for a few similar issues on recent (HP or not) laptops and found a few similar issues : Bug #1523100 Bug #1837821 so I guess this is a generic alsa or snd-hda-intel issue with newer ALC2xx hardware. I already tryed quite a few of the workaroubds/fix available here and there (e.g. overriding pin with hdajackretask, adding options to snd-hda-intel module etc. none with success) I'm available to test/provide any additional needed data.
