I bought the huawei D16 to me and my wife. Her notebook has a realteck sound card inside and installing the ubuntu has no problem. But my version of this has Everest ESSX8336 inside. And when I sign in Ubuntu I haven't sound any where.
Linux github repo has changes for sound card. So, I have installed the latest ubuntu === 21.10 and update the kernel to 5.16-rc1. But it doesn't help to me.
I got only dummy output inside settings.
Screens from windows 10 where all is working correctly.
