The BBC in its infinite wisdom has changed the protocols it uses to stream internet radio.
Until last week it broadcast in AAC and WMA formats. The latter has been dropped and the former has been changed to AAC encapsulated in an HLS wrapper. HLS = Http Live Streaming (an Apple proprietory format). To give backward compatability the Beeb has put in place an International but low quality MP3 service.
Unfortunately Aunty didn't think it was worth telling anybody that this was going to happen. That's not quite true they did post something in September on an obscure blog and they did notify some of the internet radio manufacturers. It appears however that their notification to the manufacturers was to say the least misleading and most (all?) interpreted it as meaning that AAC was going to continue and did nothing.
This folks is why your expensive Sonos equipment cannot currently pick up the rugby, football or cricket world cup any more. The Sonos (along with virtually all other manufacturers) has had to fallback to the International MP3 streams and for licencing reasons these do not include live sport.
The AAC streams used to provide Radio 3 in HD quality (320 kbps). That's gone. You must listen to the international MP3 streams (128 kbps).
To cap it all the AAC stream was also used to provide a specific service for blind people. That's gone as well.
It has caused a bit of a stir on most of the UK based AV forums. You can listen to the high quality stuff on an Apple iOS device but not on an expensive Sonos, Cambridge Audio or Naim (or other manufacturers) music streamer that in many cases the BBC encouraged you to buy by their constant banging on about HD audio on Radio 3.
If you want to listen to the cricket world cup on your aforementioned Sonos, Cambridge Audio or Naim streamer well you can't !
Fortunately I use Squeezeboxes. The active developer community has already written a workaround since the bloomers went down on Friday.
Aunty is calling this new delivery mechanism "Audio Factory". The facts are they haven't done the research, consulted properly with the manufacturers or advised us the public of their intentions. They have well and truly dropped their bloomers.
