Vanilla kernel wont work either atm, you will need my topic/sof-v4.13 branch from here :- git://git.kernel.org/pub/scm/linux/kernel/git/lrg/asoc.git Note that this branch only works on the SOF 1.0-dev branches (that are not stable) and not the stable master branch. The stable SOF master firmware branch has a different IPC ABI and only works with the topic/reef kernels (that unfortunately dont support PCI mode on Edison) :( > What exactly should happen once the mrfld_sst SFI IPC is enumerated?

The sst driver is for Intel's closed source FW. The open source FW uses different ABIs and APIs to the closed source version, currently you need to blacklist the old SST modules in order to load the SOF FW and driver (this is being fixed in upstream atm) > I guess, the nocodec mode would be fine as a start. > Yes.
