I’ve used SiriusXM for the past 2 years on my Sonos with no problem. Last week it started intermittently stopping playback. It would start again if I hit play again. Starting last night I got “This channel is no longer available” when choosing it from my favorites”. It was still available and eventually worked after closing the Sonos app and reopening. Today, the same favorite just blinks like it is about to play and then doesn’t. When I go to Sirius XM in the Sonos app and choose a channel, I get “The connection to Sirius XM was lost.” Sirius plays of course through Airplay and from the Sirius XM app and the Web with no problem. - just never through my Sonos speakers - which makes them very expensive bricks.
There are many threads on this repeated issue and I tried all the reported fixes. The Sonos site says XM is up and running. I disconnected Sirius XM within the Sonos app. I also tried uninstalling the Sonos and Sirius apps and created a new password in Sirius as previous people have suggested. I tried restarting the phone It doesn’t work.
By the way, the Sonos app has crashed on me many times since upgrading to the S2 app a couple of months ago when I try to play almost anything on my iPhone 11Pro Max. Just now for example, I started playing a book from Audible and the app crashed while the book kept playing through the Sonos speakers. I am currently running iOS 14.4. I tried to get tech support and even though I’m within the chat hours on a Saturday it says no one is available. Any suggestions?
