Auto detection of Headphones not working

I recently installed Arch Linux on my Dell XPS 9360 (late 2016 Skylake model), and im on the 4.8.13 kernel.

The problem i'm having is that when i plug in my headphones they aren't automatically recognised by the system. I either have to go into System Settings > Multimedia > Audio Volume > Output Devices (I'm using KDE) and switch from speakers to headphones there, or the other option i've found is to activate the headphones using amixer and alsamixer and to deactivate the speakers as well.
The computer was first running Ubuntu 16.04 and i had the same problem, but didn't find any solutions.

I've found someone with a similar problem in the Manjaro Forum and I've tried a few things that were suggested there but nothing worked. Does someone have an idea what might be the problem here?

Re: Auto detection of Headphones not working

The kernel docs suggest trying different model options which are listed here for that codec (i think.)

The output of the alsa-info.sh script might be helpful. Download it, run it, let it upload, and post the link here.

Re: Auto detection of Headphones not working

I ran the alsa-info.sh script, the output is here

How would i go about changing the model options for my BIOS?

Re: Auto detection of Headphones not working

To try out the different model options you can do:

# rmmod snd_hda_intel
# modprobe snd_hda_intel model=dell-headset-multi

Then check if that solves the problem. Repeat that for each model option and see if any of them solve the problem. If one does you can then put that option in a file in /etc/modprobe.d/  See Setting module options on the wiki.

If none of them work that's when you'd search for and/or file a bug report at https://bugzilla.kernel.org
