Audio on Lenovo Yoga C630 WOS

[RussianNeuroMancer]

Hello!

After reading this comment I copied mentioned firmwares to Linux partition and tried to boot kernel from wip/c630-v5.5 branch of this repository with this config. Unfortunately, audio driver doesn't start with following errors:

Noticed I been missing UCM configs. Put it into /usr/share/alsa/ucm2 and msm-snd-sdm845 is trying to start now, but there is no audio nevertheless:

@RussianNeuroMancer I don't know why this differ between Srinivas' machine and mine, but I've had to make the following adjustment to the ucm files to get it working in my Arch Linux installation.

I tried to download this folder and copy it to /usr/share/alsa/ucm and /usr/share/alsa/ucm2 (not sure which one should be used; I deleted previous UCM from Srinivas repo) and also deleted /var/lib/alsa/asound.state but this does not help, dmesg is the same (I could upload newer one, if necessary).
