No Audio Output / Dummy Output

Hey i am new here and trying to get a working linux distro on my little windows tablet. On Ubuntu Mate almost everything works except the sound.

I tried the solutions on this site: https://itsfoss.com/fix-sound-ubuntu-1304-quick-tip/
but sadly it didn't work. When opening alsamixer there are no regulators i could change.

Hope someone here can help me out.
