Your dmesg output is showing an error:

[ 1.494304] snd_hda_intel 0000:00:1f.3: failed to add i915_bpo component master (-19)

It seems that a lot of people with similar hardware are showing the same issue on Ubuntu LTS, including this guy:

Follow the same procedure he followed, here:

This will give you a newer version of ALSA which doesn't choke on Skylake audio.

This sounds like an issue you are having with the pulseaudio control center (pavucontrol).

Try finding the volume control widget on your taskbar. There may be a button there called 'mixer' or something that leads to pavucontrol. This is what it looks like:

https://www.google.com/search?q=pavucontrol&num=100&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj326SVlJvKAhWl2aYKHWC1AlYQ_AUIBygB&biw=1543&bih=895#imgrc=RoQOUIfRFSnbLM%3A

If you can't get to it through the taskbar then you can just open up a terminal and type 'pavucontrol&' or just 'pavucontrol' from a launcher dialog.

When you install a new graphics card that provides an audio device, it can happen that the new audio device gets floated to the top of the list in pulseaudio, necessitating that you change the setting manually in pavucontrol.

If you start off on the 'playback' tab in pavucontrol you might get confused because you are seeing per app output control, allowing you both to adjust the volume level and control the output device for each program that is running at the time. You should instead start from the rightmost tab, labelled 'configuration'. Temporarily disable the GK104 HDMI Audio controller from that tab by setting it to 'off'. Then go to your 'output devices' tab and see if you can find your on-board audio among the devices listed. Then go to your 'playback' tab and make sure you have a program running that uses audio. You might try opening a movie in vlc for example. At this point you might get lucky and find that pulseaudio has already selected your on-board audio as the output device for that program.

If this is not the case, or if you just want to be able to re-enable your GK104 HDMI audio device without making it the default, then you should use your distro's method for setting an audio device as default. Depending on your distro, this could be as simple as moving to the 'output devices' tab and depressing the green check box next to the desired audio device while leaving it undepressed for all other devices.

So to be clear, there are only 2 outputs listed on the configuration tab, one being the dummy output and the other being the GK104?

Can you try typing 'sudo alsa force-reload' from a terminal and see if that changes anything?
