[Solved] No sound on HP ProBook 450 G3 (Intel Skylake)

Solution found!

Edit: Not enough searching. I managed to find the solution on AskUbuntu. I have no idea what these options do and I have no idea if/where they should be added to the Wiki.

I'll leave this post here so other Archers might find the solution easier.

For 5 years I never had major trouble with Arch, but now I got a new laptop and the sound doesn't work.
It works on Windows, so the hardware is OK.

The laptop has internal speakers, microphone and a combo headset mini-jack I would like to use -- none of these work on Arch, all work on Windows.

I know next to nothing about hardware issues, but to me it seems like it only recognised HDMI and not the internal speakers, audio jack nor the microphone.

What I tried so far:

Reading https://wiki.archlinux.org/index.php/Ad … leshooting.
Trying out the kernel in [testing] (with a reboot).
Installing / uninstalling pulseaudio & jack.
Adding myself to the audio group.
Searching this forum for similar issues, esp. regarding the G3 laptop. (This one is different and concerns an earlier 2013 "G1" model).
Finding some guy on the internet who claims that the 2015 Intel Skylake integrated sound architecture is already supported by the stable kernel because it just works for him out of the box (couldn't find a proper source).

https://wiki.archlinux.org/index.php/Ad … oard_sound seems relevant.

There may be a problem with two conflicting modules loaded...

Uhh... judging by the $ lsmod | grep snd I done (output further in the post) I have nothing like snd-intel8x0 loaded (should I?).

options snd-hda-intel model=model

Now this sounds great but I have no idea what 'model' do I have.

$ grep Codec /proc/asound/card*/codec*
Codec: Intel Skylake HDMI

Is that even helpful?

AlsaMixer screenshots with Pulseaudio and the basic Intel Skylake driver: http://imgur.com/a/prZma (without pulseaudio I only see the S/PDIF outputs).

Some information as to their purpose is provided by modinfo snd-hda-intel. Look at the lines that start with parm:

I have the same laptop and had the same problem with sound. Your solution works for me too. Thanks a lot.
