Thanks for this info. The long-name contains DMI info, so I updated the
configuration in this way:

https://github.com/alsa-project/alsa-ucm-conf/commit/ac8319245e1213e46a1ae5c2de4ddd4a0c8926e2

https://github.com/alsa-project/alsa-ucm-conf/commit/9bd0bf34a571a4a3c38d74098972d82c58fac80e

(everything is in the updated 'import' branch)

So you can add the specific config for the Dell device, too.
