My SiriusXM service works fine through the Sonos app.

Have you tried removing the service and reinstalling it? Resetting the Sonos app? Restarting your phone?

I am having the same issue. I have removed and reinstalled Sirius. Re-verified and all channels are still greyed out.

Then I would recommend you call Sonos Support directly to discuss it.

When you speak directly to the phone folks, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

I have called customer support and the rep had no idea and suggested coming to this forum. 

Odd. Since you haven’t bothered to tell us what steps you have tried, or what suggestions Sonos support had you check, this community is likely to suggest lots of things you may have already tried.

Without further information, I’d suggest a few things, with no guarantees. First, check your account at www.sonos.com to ensure your account is set up with the appropriate address. It’s a long shot, certainly, but worth checking. 

Next, perform a network refresh, by powering down all your Sonos devices, and reboot your router. Give the router a couple of minutes to come back up before plugging back in your Sonos. 

I’d also check in your Sonos controller for any software updates, or firmware updates for your devices.

I’d also be aware of any port blocking, such as VPNs, work profiles, pi-holes, or virus protection that might be blocking access to the SiriusXM server(s). 

I did the steps mentioned in the first post. Everything is updated, router has been rebooted. I have a feeling it is because I have S1 equipment, but the Sonos technical support did not say anything about that being the possible issue. 

I’m having the same issue with SiriusXM channels being greyed out.

I have tried all suggested steps, including uninstalling the music service(multiple times) I have rebooted my router and all 5 of my sonos products. I can listen to SXM on my iPad and on my laptop with no problem, but Sonos will not play anything, music, sports, talk. They are all greyed out on the Sonos app on my iPad or PC.

I have just upgraded my home network with a new 6G router, and had to go through all the steps to do a factory reset of all my Sonos products. All other streaming services work fine. SXM was working OK on my old network, although I had noticed the reported issue with songs skipping and changing mid-song.

I would love to hear if someone has a suggestion, as this is driving me crazy.

Finally got SiriusXM working.

First, I went to the Sonos app in the Manage drop-down. Select “Service Settings” tab and then “Services”.

I then selected the SiriusXM service and clicked the “Remove” tab to uninstall the SiriusXM service.

Then go to the “Add” tab, select SiriusXM and click the “Install” tab. This takes you to the SiriusXM authorization screen. I had to authorize using my SiriusXM ACCOUNT login/password, which was successful in adding the SXM app, but all channels are still greyed out.

Lastly I went back to the “Service Settings” tab and hit the re-authorize tab and entered my SiriusXM APP login/password. All channels immediately became colorful and could be played.

It all has to do with your SXM Account login(from your car radio and payment info) which is different from your App credentials. Not sure why the SXM authorization does not like your email login(you’ll get the error message) so you have to authorize Sonos to access your SXM account with your account login credentials, and then re-authorize SXM in Sonos with your SXM App login credentials

Hope this helps any others, as it was driving me crazy since neither Sonos or SXM tech help seems to understand the problem.
