After bisect on kernel, the https://github.com/torvalds/linux/commit/df1fceacb24853d79f41a1dd717b32ab08fa5f3f is the commit which cause the "no soundcards found" failure.
I can try to find the lost firmware for the Intel SST as the dmesg indicates ``` [ 24.760781] snd_soc_skl 0000:00:1f.3: Direct firmware load for 9d71-ACRSYS-ACRPRDCT-2-tplg.bin failed with error -2 [ 24.760788] snd_soc_skl 0000:00:1f.3: tplg fw 9d71-ACRSYS-ACRPRDCT-2-tplg.bin load failed with -2, trying alternative tplg name skl_hda_dsp_generic-tplg.bin [ 24.760809] snd_soc_skl 0000:00:1f.3: Direct firmware load for skl_hda_dsp_generic-tplg.bin failed with error -2 [ 24.760811] snd_soc_skl 0000:00:1f.3: tplg skl_hda_dsp_generic-tplg.bin failed with -2, falling back to dfw_sst.bin [ 24.760828] snd_soc_skl 0000:00:1f.3: Direct firmware load for dfw_sst.bin failed with error -2 [ 24.760829] snd_soc_skl 0000:00:1f.3: Fallback tplg fw dfw_sst.bin load failed with -2 [ 24.760831] snd_soc_skl 0000:00:1f.3: Failed to init topology!
