As an aside - If you uninstall myMPD on the SO machine for any reason, you may have a difficult time reinstalling…I did. Using 1.2.10 FW and Ubuntu 22.04.1 LTS on an Intel atom minipc.
I ended up having to drag/drop another myMPD .deb file installation into SO- searched “myMPD Ubuntu jammy” and found a download, myMPD 9.1.2 and amd64 version for my case. It worked fine though. amd64 build of mympd 9.1.2-1ppa2~jammy : myMPD : Minho Park (launchpad.net)
Still working on the upmpdcli issue for DSF, if anyone has any advice would be interested.
