BBC radio streams not working

[Cebolla]

Yes, ffmpeg as I've been mentioning - I don't use avconv.
Not sure what the point would be requoting the URLs for above streams mentioned by Simon Hughes is. Admittedly I didn't try them all, only the 320kbps ones.
Yes, I am using MinmServer's standard feature of providing radio streams and getting it to use the MinimStreamer transcoder, via a 3mu file.

I'm currently listening to Radio 5 live, for example, via the Foobar2000 player as a UPnP Renderer (requires the foo_UPnP plugin) and using MinimServer. You can actually view the URL it's using to connect to MinimServer, which in the above stream's case is
http://192.168.1.9:9790/minimstreamer/*/...nscode.wav

My version of Foobar2000 doesn't natively support streaming of HLS AAC, BTW.
