Hello I own a MateBook D 16 AMD R5 16GB+512GB (HVY-WAP9). It has an Everest I2C audio sound card.
Unfortunately, the sound and microphone does not work with any Linux
distro. Even the latest kernel 6.1 RC with Arch does not get sound. The card is not recognized at all. Since Huawei also has Deepin notebooks, can you somehow compile it appropriately and provide it as an update for Deepin 20.7 / 20.8?
Also the fingerprint does not work, I can live with that, but without sound is annoying. Sure about Bluetooth I can pair external speakers. But it would be better if the sound card Everest I2C audio would work under Linux.
