Comment 39 for bug 2029010

So I managed to make the sound work on my matebook D14 AMD 2021 laptop with ryzen 5 5500U.

Upstreaming the driver might be difficult.
I can provide a patch to those interested, but that means you will have to compile your own kernel.

Also take into account that there seem to be several versions of this HW combo so the patch might not work without some modifications.

I would like to find out if there any interested people here for the patch.
If yes, I will need some additional information to make the driver work on your HW:
cat /proc/cpuinfo
sudo dmidecode
cat /sys/class/dmi/id/modalias

install acpidump and iasl utilities, on ubuntu they are in the package acpica-tools, and then run the commands(create an empty folder and run the commands inside it):

sudo acpidump -b
cat * > acpidump.bin
iasl -d acpidump.bin

And then attach the file acpidump.dsl.
