Hi,

On more recent kernels legacy HDA stops working for device 8086:9d71:
[   47.211381] snd_hda_intel 0000:00:1f.3: DSP detected with PCI 
class/subclass/prog-if info 0x040100
[   47.211383] snd_hda_intel 0000:00:1f.3: Digital mics found on 
Skylake+ platform, using SST driver

However, only legacy HDA supports it:
00:1f.3 Multimedia audio controller [0401]: Intel Corporation Sunrise 
Point-LP HD Audio [8086:9d71] (rev 21)
..
	Kernel modules: snd_hda_intel

Ubuntu kernel doesn't select SND_SOC_INTEL_SKYLAKE, which builds 
snd-soc-skl, because based on the Kconfig description SOF should 
support it.

I wonder if SND_SOC_INTEL_SKYLAKE should be select again?
