@Paolo,

So far, both ucm2 from upstream and ucm from Intel only support 2 speakers, for Bass speakers support, the upstream is discussing it, please read this thread： https://mailman.alsa-project.org/pipermail/alsa-devel/2020-February/162701.html, if you have some idea, please reply that thread.

And after the Bass speakers support is ready, I will co-work with Intel audio team to backport it to ucm. (maybe need some change in the pulseaudio too.)
