sirius xm radio will not play

On macOS, play SiriusXM Radio in the browser or using a third party app, like Radium. A number of other third party apps that also had that capability have been ‘retired’ for a while, unfortunately.

Try Safari/Preferences/Websites/Auto-play and set the site to Allow all auto-play.

See if anything here helps.
