I downloaded the 1.2.9 alsa-lib (tar) files from the alsa website which did not have ump files as they do in the git 1.2.9 repo. I found this https://packages.ubuntu.com/search?keywords=asound Seems libasound2-dev is based on 1.2.9 but is for the next distro release (23.10) . Strangely, in the file list there are no ump files. 1.2.9 is the already released one. The UMP support *will* be included in 1.2.10, once when released. The git version is a bleeding edge code, that is, would-be-1.2.10. Takashi
