Audio actions in routines are currently not supported on this device.

I agree that the Alexa integration needs to be much better, I’m very disappointed with that experience. I’d also love to be able to use it to group rooms to play music too but it doesn’t look like any progress is being made with that either.

I suggest you read this link:

What I find peculiar is that despite saying it's "not supported on this device", it still works: https://twitter.com/customeroutrage/status/1083697659456770048

I believe I have figured out the problem. My Alexa-enabled Ecobee4 does the same thing. If you have a routine called “goodnight” which turns off all your lights, a true Amazon Alexa device will turn off all your lights AND say “goodnight, sleep tight” (or something similar). Our Sonos (or Ecobee4) are merely “Alexa-enabled” and aren’t full features Alexa devices. And they hit a brick wall with attempted conversation. If you create an identicle routine, with a nonsense name (“Waffle House”), your routine will be completed without a failed attempt to respond to you / the error message. Let me know if you think I’m right. But after a bit of research, it’s what I think I’ve figured out.

I just tried your exact example - changing my “turn off lamps” routine to “Waffle House”. The lamps turned off, but still the same phrase stating she didn’t support what she’d just done.

I'm with the others above that think this is a new problem. I've had a Sonos One in my system for about 7 months using quite a few routines and I don't think I've heard this till I added a new one today - which brought me to this thread.

The routines all apear to work... even any configured dialogue where Alexa responds but this new incorrect error message gets added in.

Per this chap having the same issue with his EchoBee: https://youtu.be/p4U7X3zq0bA the behavior seems inconsistent and some routines work without adding the message. It is as if Amazon have configured some whitelist of expressions/grammar intending to capture things that don't work (I have a strange feeling that some things used to fail silently). Unfortunately it would seem they forgot to handle the case of free form routine triggers. Given the same happens on other Alexa-enabled products that does suggest Amazon are the source of the problem. You'd think Sonos would be following up with them however as it is Sonos that lose out here.

I wish I had never bought the Sonos One. Dot + a Play works much better, especially with the Group "default speaker" thing.

“I wish I had never bought the Sonos One. Dot + a Play works much better, especially with the Group "default speaker" thing.”

This I think sums up the experience of many users lured into this by the unclear marketing (to not say deceiving). What indeed is the point of the Sonos One when the best solution was clearly Sonos Play + Dot?

As a person new to both Alexa and Sonos, I don’t get it.

This is an Alexa problem for some class of devices (undetermined). This isn't limited to Sonos, Eco Bee has the same issue reported as does the Alexa app on the iPhone. Try using the Alexa app to run the routine with your voice. Then run the same routine on the Alexa app using the play button next to the routine. Only voice activation gets the annoying message.

I think this issue might've been resolved as of tonight. We have a "good night" voice routine that we use from the Beam in our bedroom. Wed got used to sarcastically chanting "Audio routines are not supported..." and then suddenly tonight, the routine just ran without a fuss.

Could you please add an audio action to your routine and see if the error message comes back again or not? It seems that the error message happens only if you add an audio action to your routine.
