Hi,

This version of firmware[1] is not signed by Intel. The Comet Lake (CML) processor will validate the PV bits of the firmware, and it will refuse to load the sof-cnl.ri firmware

sof-audio-pci 0000:00:1f.3: error: load fw failed ret: -110

This SRU breaks the DMIC on CML platform. Please kindly replace the firmware binary for the CML platforms.
