Thanks for the quick answer @crojewsk. But I didn't see
skl_hda_dsp_generic-tpkg.bin in linux-firmware repo yet. When can we
expect the skl_hda_dsp_generic-tplg.bin or dfw_sst.bin in the linux-

Hello,
Similar issue has been opened on bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=212081
Whenever in doubt of skylake-hda_dsp configuration, please see:
Linux: HDA+DMIC with skylake driver
https://gist.github.com/crojewsk/4e6382bfb0dbfaaf60513174211f29cb
And the following kernels don't work for me, still no soundcard
lspci: 00:1f.3 Multimedia audio controller [0401]: Intel Corporation Sunrise
Point-LP HD Audio [8086:9d71] (rev 21)
dmesg: [ 41.044565] snd_hda_intel :00:1f.3: DSP detected with PCI
class/subclass/prog-if info 0x040100
[
confirmed the same issue running groovy on a Xiaomi redmibook(alc256m
with intel dmic)， stock kernel detects dmic and drops to sst driver，
which won't work at all， disabling dmic detection in alsa enables
speakers but 3.5mm only works as mono，solutions about intel sst driver
need to be backported
Could you add the following to /etc/modprobe.d/alsa-base.conf (and
reboot):
options snd_hda_intel dyndbg=+p
options snd_soc_skl dyndbg=+p
options snd_soc_skl_hda_dsp dyndbg=+p
options snd_intel_dspcfg dyndbg=+p
Then provide the full dmesg results. Thanks!

Re installing linux-modules-extra, that doesn't help.
I tried this latest test kernel: it does not fix my audio, and it breaks
my touchpad too.
