This is odd. I checked internally a few weeks back and the CML PCI ID 
was 9dc8, same as WHL and CNL, so we did not add a PCI ID on purpose. To 
the best of my knowledge SOF probes fine on CML and the known issues can 
be found on the SOF github [1].

Care to send the log of sudo lspci -s 0:1f.3 -vn ?
