And yes I did reboot my router.  And did unplug and then plug in all my speakers.  No change.  Thank u.

So, a few questions, since your experiences point to some sort of network disconnects. Perhaps simple wifi interference , or a duplicate IP address issue, or a DNS issue, or problems on SiriusXM’s server. 

When you rebooted your router, were the speakers unplugged from power, or did you do that in two different processes? Have you submitted a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it?

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

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 Sonos system and network.

Thanks for the response.  I rebooted the router and then later did the power disconnect on the speakers.  So not at the same time.  I will follow your other advice shortly.   I should add that Spotify… Amazon Music…  Tune In…  and Sonos Radio... all play just fine.  This issue is only with SiriusXM.  Thanks!

That tends to point to the issue being with SiriusXM, with one small caveat. If it’s a DNS issue between your speakers and SiriusXM, then that process will definitely spread the DNS changes to your network. 

But if the issue is on SiriusXM’s side, this process, while it won’t harm anything, won’t fix the problem, either. You’d need to contact them with your concerns. 

@Arnie328 - I wanted to let you know that you are not alone. I have also been experiencing this issue frequently for the last several weeks. There is also a report on Reddit: SiriusXM "Unable to play selected item" error with station selection : sonos (reddit.com)

Past experience shows that this type of problem is difficult to get attention on from SiriusXM themselves, as their customer support fails to grasp the basic issue and if the SiriusXM app (iOS, etc) works, they just point the blame back at Sonos.

Thanks sves.  It is good to know I’m not the only one.  And none of that surprises me.  

I see today my app updated to 15.10.  And it played SiriusXM right away!!  Could be a good sign?  Or could just have been luck that time?  We’ll see.  Thanks!

24 hours later.  15.10 working much better.  I hope this is it.  Thanks all.
