DLNA, online radio and Sonos

[irah]

I had a similar question, not sure if it is the same thing.  I would like to cast a Live TV channel that is an Internet radio station.  By "cast" I mean send the Live TV channel to another device by clicking on the cast icon that is between the group icon and the search icon on the top right in the UI.  The device I want to cast appears when I click the cast icon.  Is it possible to cast Live TV to another device, but not Internet radio?

On Ubuntu 24.04, Jellyfin 10.10.0, I can "cast" music from my music library to a sonos, by selecting the sonos device as the output device (using the cast icon to select the device).  But when I play an Internet radio station that is configured as a Live TV channel, and then try to "cast" that to a sonos by clicking on the cast icon and selecting the device, the UI just sort of freezes and it doesn't play.   

I see this error in the jellyfin log:
