@Hui Ok thanks. Last night I re installed from scratch Ubuntu 20.04.1 and I noted a variation: to make the sound to work I needed to add your testing repo and to do an upgrade. Previously I fixed the sound issue by simply adding the two missing folders in ucm2 and ucm2/codecs for chtmax98090 sound card.
