Ubuntu 16.04 no sound with asus Xonar DG

There is no ALSA driver version which is the issue

what I further did was:

If the ALSA driver version number in the Terminal output does NOT contain anything at all, please execute the following commands, then reboot and retest sound output using headphones and speakers:

sudo apt-add-repository ppa:ubuntu-audio-dev/alsa-daily

sudo apt-get update

sudo apt-get install linux-image-extra-`uname -r`

sudo apt-get install --reinstall linux-image-extra-`uname -r`

sudo apt-get install oem-audio-hda-daily-dkms

Then reboot and retest sound output.

thank you for your support, unfortunately after having installed the ALSA driver there is still no sound !! Due to the fact that i'm a Ubuntu beginner I'm still searching for a workaround/solution,

currently system gives me the following information, any idea ?

!!ALSA/HDA dmesg
!!--------------

I found in the above report that I've different ALSA versions on my installation, what could cause the problem.
I really do not understand why this can happen after a new installation, however how can I cnage the library versions to k4.4.0-22-geeric ?

!!ALSA Version
!!------------

Driver version: k4.4.0-22-generic
Library version: 1.1.0
Utilities version: 1.1.0

Thanks Mark Rijckenberg, that solved my question.
