What URL’s are you using? Many of these stations change the links often as they seem to want you to visit their web page instead of using your own app.
Using the Inspect Element function in Safari or Firefox, then Network, then Media you can find the URL of the station but after checking on the BBC 3 station, it seemed they changed something a few months ago so that could be an issue there:
Here in the UK we use BBC iPlayer for BBC tv and BBC Sounds for radio. These are accessed through the BBC website.
On the iPad and iPhone there are dedicated apps for each service and they work very well.
Similarly France Musique, however I cannot find it in the App Store even though I was with someone yesterday who was using it!
Another option is the Radioplayer app. I have that on my phone.
In theory , if you have Homepods (or any other ‘smart’ speaker) you are allegedly able to play BBC streams by just talking nicely to the speaker.
Thanks, @FishTickler, although I can play the stations fine via the BBC and Radio France Musique websites. What I would like to do is play them in Music, where I appreciate the convenience of having all my stations together in one place.
I noticed the same behavior when trying some of those links. I guess you can only use some in a browser or use some of the other sites recommended above by others. Fortunately, most of the stations I still listen to work in iTunes or Music but for how long time will tell.
Here’s a Reddit thread that gives the URL structure for BBC audio streams. Unfortunately, Mac Apple Music cannot handle the m3u8 file type. They will open in VLC.
I like to use my Mac as the base of my home sound system. I play a stream or playlist in Apple Music, and via the Airplay dropdown can send it multiple destinations at the same time. Unfortunately, that only works in Apple Music. I’ve tried using Rogue Amoeba’s Airfoil to enable multiple speakers, but I’ve never liked that solution. However, IOS and iPadOS permit sending audio to multiple destinations, and a Mac can be a destination. So, suppose you’re using Apple Music to send the audio to the network. In that case, one solution is to open the IOS version of VLC (or another app that can handle the BBC stream format) and use the iPhone Control Center to stream the output to your desired speakers, including the Mac.
