This would likely apply only to the UK … unless you use a vpn to get BBC Sounds on Sonos.
Currently in the USA you can listen to the BBC Radio stations via TuneIn.
And not sure that BBC Sounds in the UK on Sonos uses Shoutcast…. but thought i would post it for general information
I heard the announcement today after a news program.
the link below is on the BBC website
The BBC uses several streaming technologies to deliver BBC Sounds. If you are hearing a message informing of this change, you are listening using Shoutcast. The BBC will stop supporting Shoutcast by mid-2023.
Why are we making these changes?
Shoutcast is an older streaming technology and many connected radio devices in the UK no longer use it. Ending support for Shoutcast will enable us to focus on the two most popular technologies currently used – HLS and DASH. As well as delivering better value, it will allow us to understand more on how our content is consumed. This forms part of our strategy for BBC Sounds and is important to help us improve the services we offer to our listeners.
We informed manufacturers and other service providers of this change in May 2022.
I hear the message – what should I do?
If you are using an internet radio or smart speaker, please contact the manufacturer. It might be possible for the device to be updated to use another of our supported streams.
If you can hear the message when listening to BBC services via the web or mobile phone, please listen on BBC Sounds instead.
Other ways to listen to BBC Sounds on a Hi-Fi
There are multiple ways to listen to BBC Sounds on your Hi-Fi. If you hear the message when listening on your Hi-Fi, please contact your manufacturer. Additionally, you might find our FAQ useful – How can I get BBC Sounds on my Hi-Fi?
