audio card with Realtek ALC1150 Audio Code not found

Your ASRock Fatility Z170 Gaming-ITX motherboard is very new ( Release Date: August or September 2015) and
not well supported with older GNU/Linux kernel versions.

Kernel version 3.19.0-47-generic (in your output) is too old for Sky Lake motherboards like yours.

I also have a new PC with the Sky Lake architecture.

Even though Ubuntu 16.04 LTS is not officially released yet, I had
better luck booting my PC with this version instead:

http://cdimage.ubuntu.com/lubuntu/daily-live/current/

Keep in mind that Ubuntu 16.04 LTS is not released yet and is probably
full of bugs. So any issues should be reported as a bug and not in this
Answers section of the forum.

But maybe your desktop PC will work better with the current unfinished build of
Ubuntu 16.04 LTS. Power management still does not work correctly on my
Sky Lake PC when using Ubuntu 16.04.

Apparently it is a kernel bug popping up from the combination of the Intel Skylake architecture, the 3.19 linux kernel (ubuntu 14.04) and (possibly) the Realtek ALC887 audio chipset (snd-hda-intel linux driver) which screws somehow the alsa drivers up.

The following procedure is listed at https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS but it's not up-to-date with ubuntu 14.04 (although it is totally equivalent):

Make sure the dkms package is installed:

sudo apt-get install dkms

Then download and install (e.g. with ubuntu software center) the .deb file from the latest vivid alsa build at https://code.launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa-daily/+packages

When I did it, it was the following build:

oem-audio-hda-daily-lts-vivid-dkms - 0.201509251531~ubuntu14.04.1

where the 2 keywords are 'lts-vivid' and 'ubuntu14.04'. That is what you are looking for.

My system is the following: Asrock MB with b150 chipset (ALC887 sound card) and Intel i5-6500K (Skylake) with 8GB RAM and an NVidia GTX960. I also did not see any audio device, except for the video card hdmi outputs. Very nasty bug, as there is so much confusion around the sound system (alsa and pulseaudio) in ubuntu apparently, so that to find the same bug report is quite difficult.

I know this is exactly what Abe commented last, but I would like to see it as an answer, clearer to see immediately without having to browse through the comments.

Thanks actionparsnip, that solved my question.

I got the above answer from the above link. Sorry I copied and based without the link :P

Still now sound card detected on my computer.
