Here the same in the Netherlands.
Alarm station is set to 3FM but random dutch station are playing at alarm.
Actually the stations name is “NPO 3FM” but that's not a choice only 3FM in the list.
Old station logo in player.
Hi @pswinny and @ekeeman, welcome to the Sonos Community!
Thanks for bringing this up and I’ll be happy to help.
Can you please check what music service are you using when setting a Sonos alarm? Is it also okay if you try to check it with a different music service to isolate the problem?
Submit a diagnostic report of your system to further check it on our end and reply to us with the confirmation number.
Just let us know. We greatly appreciate you being a part of the Sonos family. It is our pleasure.
Problems were with sonos Radio.
Now I use Tunein for setting the alarm for a radio station, and it looks like problem solved.
Also a bad thing that Radio statons are unsorted in picklists.
Hi @ekeeman, thanks for your reply. It’s great that it works with TuneIn now. Is the radio station that you set in TuneIn that did work is the same station you set in Sonos Radio? What do you mean unsorted? Is it in Sonos Radio as well?
Keep us posted here. We and the community are always here to help.
Yes the same station, maybe with a different name in the picklist. In tunein it is it's official name “NPO 3FM” in Sonos it's "3FM” in the picklist.
The picklist is unsorted. Sometimes there are a lot of stations to choose from, if those stations were sorted bij name they are easy to find in large lists.
I don't think it's great for sonos that is works with tunein. It should work with sonos' own radio service.
On my sonos system i would prefer Sonos Radio better than Tunein.
Hi @ekeeman, thanks for the details and appreciate that you prefer to use the Sonos Radio. We also apologize for the inconvenience and just to let you know that we are always working to improve the experience and we are working hard to resolve this issue. For now, use the TuneIn service or any other services applicable to your region if your preferred station is not working well with the Sonos Radio.
Let us know if you still need anything. We and the community are always here to help.
I have this exact issue with BBC radio 6 via Sonos radio for my daily alarm. Some mornings it plays a totally random station but shows that it’s playing BBC radio 6. I’ve had this consistently since switching to Sonos radio.
Thanks for the suggestion of using tunein directly rather than Sonos Radio. I’ll give that a try but it would be great if this bug could be finally fixed.
Hi @fintrepid, thanks for reaching out here with us and sharing your feedback. We’ll continue to work with that. Just let us know if you need anything. We and the community are always here to help.
I recently began to have this issue. On a pre-set alarm, Sonos chime would play instead of a radio station. I was using the Tune In radio service and changed to Sonos Radio. This worked for a few days and then reverted to the same problem.
I stop the chime physically on the Play 1 and then use the app to select a radio station.
Any suggestions?
Hi @GarvanIrl, welcome to the Sonos Community, and thanks for reaching out here. I’d be glad to help and confirm if the station you set working when playing manually in the Sonos app? Have you tried a different station or service if that will work with your Alarm? Keep us posted here. We and the community are always here to help.
Hi
It’s totally random. I have a Sonos One in my office, a Play 1 in my bedroom and kitchen and a beam and 2xOne’s in the TV room.
At times one room will be on the app and the others have disappeared
Sometimes volume control doesn’t work or radio station/song won’t change when selected…..
This morning the alarm worked as programmed i.e. the correct radio station came on
Other mornings it’s the Sonos Chime or a different radio station
Oh and sometimes the app displays the correct station but it’s playing another….
Chime in both (bedroom & kitchen) alarms this morning 
...and this morning the correct radio station
