I bought a new Zenbook 13 and installed Ubuntu 17.10.
Unfortunately, I can not get any sound output (neither internal speaker nor headphones). It is a dual boot system and the sound just works fine in Windows 10.
Already tested GNOME ALSA Mixer but it was not successful. Hope someone can help.

  • I just started Ubuntu and suddenly the sound works. Since my post yesterday I rebooted multiple times, switched from Windows (gaming) to Ubuntu and back but did not do any changes to my system. I hope it just works from now on even though I would to know what caused the issue. – user2504694 Dec 15 '17 at 08:35

The problem is the linux alsa driver doesn't know how to deal with this sound card correctly.

Now that I had a few more days to experiment I found kind of a solution for my situation: When I run Windows 10 and restart the computer to switch to Ubuntu the sound seems to always disappear. However if I turn the computer off and then switch it on and load Ubuntu the sound seems to work. Still do not really understand what is causing the issue.
