That's great, thanks!

The Asus MJ401TA has Intel m3-8100Y (Amber Lake) and this audio controller:

00:1f.3 Multimedia audio controller [0401]: Intel Corporation Sunrise
Point-LP HD Audio [8086:9d71] (rev 21)
         Subsystem: ASUSTeK Computer Inc. Sunrise Point-LP HD Audio [1043:18b1]

The kernel tries to laod sof-kbl.ri and sof-kbl-nocodec.tplg for this product.

This product has a digital MIC that works fine under Windows. However
this does not seem to be supported by the closed FW:

 snd_soc_skl 0000:00:1f.3: DSP detected with PCI
class/subclass/prog-if info 0x040100
 snd_soc_skl 0000:00:1f.3: enabling device (0000 -> 0002)
 snd_soc_skl 0000:00:1f.3: undefined DMIC array_type 0xf
 snd_soc_skl 0000:00:1f.3: bound 0000:00:02.0 (ops 0xffffffffad150080)
 skl_hda_dsp_generic skl_hda_dsp_generic: Unsupported HDAudio/iDisp
configuration found
 skl_hda_dsp_generic: probe of skl_hda_dsp_generic failed with error -22

So I believe there is device support missing here. We would be happy
to lend a product sample to Intel if that helps get this solved.

Thanks!

Daniel
