before i saw this bug thread i found another (
http://askubuntu.com/questions/700167/no-sound-on-ubuntu-15-10 ) thread where i
realized you only need to add two lines to the config:
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.
i just post some lines from the terminal which might help:

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.
