Apologies I have misinterpreted what the user-space code expects, it seems (as per https://github.com/alsa-project/alsa-ucm-conf/blob/master/ucm2/README.md) that the UCM file path is derived from long_name, not name, and name is only used as a fallback if long_name is not provided. Will send a v3 just adding a long_name instead. Regards, Ryan
