Great ! Found the files. Thanks so much. BTW found the discrepancy. 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.
