At first there was no native recognition of my sound driver (see this [ https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1525554 ] a lot of others a experiencing this problem)
so there was a workaround to fix that, the notebook has sound output now, but ever since i got these horrible scratching noises while booting, which i dont have booting windows, which is kinda surprising while one could take it for a bios or hardware problem.
basic workaround for fixing missing sound driver was adding two lines to the /etc/modprobe.d/alsa-base.conf
options snd-hda-intel single_cmd=1
options snd-hda-intel probe_mask=1
with these lines a was able to get sound, but i then have these crazy noises while booting.
the following are some lines from the terminal which might help:
'lsb_release -rd'

even adding the right driver and module into /etc/modules (like snd-hda-intel model=PCH index=0) did not work, like i found in this thread ( https://wiki.ubuntuusers.de/Soundkarten_konfigurieren/ ) sorry for the german thread.
i dont know what to add anymore. feel free to ask.
