FYI @mengdonglin @btian1 @andrula-song @abonislawski @ujfalusi

@kv2019i , main or mtl_006 branch?
kv2019i commentedon Nov 9, 2023
This bug occures with SOF2.7.1 released, but it seems this is fixed in both SOF main and mtl-006.
btian1 commentedon Nov 10, 2023
yes, it is not reproducible on SOF main with latest on MTL HDA rvp, dmesgshowed CPC are correctly loaded:
@kv2019i @mengdonglin , can we close it for now?
kv2019i commentedon Nov 10, 2023
@btian1 Thanks for double-checking, let's close but good to have this as a reference if any SOF2.7 user hits this. Fix is coming!
