I did try disabling fast startup and installing the brand new 5.19.1 kernel, but still no luck. BTW, can you please explain to me a bit how can a feature switch in Windows affect something working in Linux? Does this Fast Startup actually manipulate the BIOS or something?
Also, from the link provided by nikgnomic I read that, according to some assessments, it is quite hopeless to get this sound card working unless Huawei and AMD actively contribute (which they are not very eager to do, it seems). Is it really so bad? Does the SOF project still stand a reasonable chance of getting it work under Linux?
Fast Startup is a “feature” in proprietary OS that uses hybrid hibernation to appear to restart faster
A Linux OS can fail to initialise some devices from hybrid hibernation state. The audio device might be non-functional because it is stuck in hybrid hibernation
