Headphones no longer detected after Linux kernel update 4.8.0-27.29

Asked by Ben

Hey guys!

I have a Dell XPS 9550 laptop. I'm running vanilla Ubuntu 16.10. I'm using proprietary Nvidia + Intel drivers (sorry rms...)

Headphones, headsets, mics, etc have always worked. Usually when I plug one in, a dialogue will appear and I can select what type it is.

This morning I ran "apt-get dist-upgrade", and it upgraded to Linux kernel 4.8.0-27.29. I then performed a reboot. After this, I could not get headphones to work.

If I plug them in (tried multiple pairs), I get no dialogue box. Under Sound Settings -> Output, there's only "Built-in Audio". The sound will just play through the built-in speakers.

I tried suggestions in:
- https://askubuntu.com/questions/518851/headphones-not-working-after-update-ubuntu-14-04-1
- https://askubuntu.com/questions/132440/headphone-jack-not-working

But they did not work.

Any help would be greatly appreciated :)

I noticed the following change in Linux 4.8.0-27.29:

- ALSA: hda - Fix headset mic detection problem for several Dell laptops

Might this have something to do with it?

Thanks guys!

Ben
