The issue only happens on `ba-lnlm-rvp-sdw-01`, but not `jf-lnlm-rvp-sdw-1`. And I checked the dmesg found that [ 8.481076] snd_soc_sof_sdw:sof_card_dai_links_create: sof_sdw sof_sdw: sdw 5, ssp 0, **dmic 2**, hdmi 0, bt:...

I added `options snd_sof_intel_hda_generic dmic_num=0` as a temporary solution.
