I could also access Qobuz using LMS+Squeezelite R2, LMS+upmpdcli_mpd
While I could reconfigure BubbleUPnP Server on the webpage, and make upmpdcli an OpenHome renderer I could not test it. My intention was to use Qobuz with BubbleUPnP server + upmpdcli (as renderer) but failed. Upmpdcli required the addition of Qobuz parameters into the config file, but after adding them, still failed. For the time being, will park issue.
Browse is still a problem; if anything worse than before. Cannot even copy/replace music tracks and albums. Can replace playlist but not add.
