At this point, no. Thanks for confirming the platform's name.

NHLT was left alone across all the updates. Updating it is one way of fixing problems but I don't believe it's necessary in your case. Topology update is more desirable approach.

That clarifies things out. Guess the kernel version used there is v4.4 (plus a ton of un-upstreamed patches). Again, will propagate the information up the chain. Perhaps one of the solutions for end-users would be providing working UCM files to alsa-topology-conf repo so users are not powerless in situations such as this one.
