no sound on huawei mate D15 laptop BOM-WXX9-PCB-B2

Hello. The problem applies to all distributions.
the problem is described here
codepayne/linux-sound-huawei#27

Sound support appeared only in the 6.7 kernel. Also, this parameter of the kernel config must be included in the kernel build

CONFIG_SND_SOC_AMD_LEGACY_MACH=m

There is also a regression in alsa, but there is also a temporary bypass

The fix will also appear in the 6.8 kernel, but you can apply this commit as a patch.
