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:
but sadly it didn't work. When opening alsamixer there are no regulators i could change.

Hope someone here can help me out.

inxi -SMA:

Host: mto-Aspire-SW5-014 Kernel: 5.3.0-61-generic x86_64 bits: 64

Type: Laptop System: Acer product: Aspire SW5-014 v: V1.05
Mobo: Acer model: Pancake v: V1.05 serial: UEFI: Insyde
