Description Of Issue
I’m having the same issue mentioned here.
No solution is mentioned there.
The HomePod appears as a zone and can be selected and configured. However, when I click play, nothing happens. The progress bar simply sits stationary.
I do not have the problem with other AirPlay devices.
If I play Roon to my iPad and then tell iOS to set the iPad’s output to HomePod, it works.
