Subject: Re: [PATCH v1 1/2] ASoC: SOF: Add Comet Lake PCI ID

Add support for Intel Comet Lake platforms by adding a new Kconfig for
CometLake and the appropriate PCI ID.
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].
The PCI ID change is seen on later production Si versions. The PCI ID is 02c8.
we must be talking about a different skew. I'll check, give me a couple
of days.
Care to send the log of sudo lspci -s 0:1f.3 -vn ?
Here you go:
