alsa-info.sh without snd-intel-dspcfg.dsp_driver=1
Sound card not dettected. sof-firmware and alsa-ucm-conf installed. Possible duplicate of #1176351. Booting with snd-intel-dspcfg.dsp_driver=1 works around the problem.

Could you try with snd-intel-dspcfg.dsp_driver=2 instead, i.e. using SOF driver?
I guess dsp_driver=1 resulted in the missing built-in mic.
