Due to rights restrictions…!

Ok. Right I’ve been thinking about this (it’s raining outside! 😉) . It is Sonos that we pay significant money to, not TuneIn. Sonos claims you can listen to radio. When the ‘relationship’ - whatever it is - between Sonos and radio transmission services go wrong we do naturally blame Sonos who we’ve paid large amounts of money to….
 

Unfortunately I’ve had problems with Radioplayer in the past too so doesn’t solve the issue long term….. 

I'm sorry but I still don't see this as a Sonos issue, something that perhaps we just need to agree to disagree on.  Sonos are also a content provider where they have control of content and I'm listening to BBC Radio 4 through Sonos Radio.

The fact that TuneIn and the BBC haven't agreed a contractual framework to play via TuneIn but Sonos provide the option to play via their content provision removes the responsibility from Sonos IMHO.

It’s like being mad at LG/Samsung because you spent so much money on your TV, but your local cable provider doesn’t offer HBO, or is blocking local access to a sporting event (common here in the US, with baseball and football broadcasts which are limited by broadcast agreements).

Sonos is just a ‘TV’ for the ears. They provide access to a bunch of channels that you ‘watch’, but don’t have any control over what is on those channels.

Note: this analogy does break down slightly in the Sonos radio HD channels that Sonos produces themselves, but is valid for all external company streams. 

There are tens of thousands of stations available and each station can fuss with its streaming setup and rights management at any time. It is very difficult for an aggregator, such as TuneIn, to keep current. I don’t know TuneIn’s current schedule, but at one point they updated their database once every 24 hours. They would research reported issues, but it could require a few days to resolve -- if resolution was possible.

During a local station tour I noticed a lonely PC buried at one end of an equipment rack and was told that the PC managed the station’s streaming. No one on staff understood or paid much attention to that PC and if an issue was discovered, the staff would bring it to the the attention of the network administrator when he next dropped by the station. This was not a high priority for the station.

I think it all depends on where you’re coming from… I wouldn’t spend lots of money on a TV that couldn’t receive BBC channels if I could get them on every other type of TV. This is how it seems for me with Sonos…. 

You couldn't really complain if you lived in the Shetlands and couldn't get BBC One Channel Islands.on your TV. 

A Sonos device is simply the endpoint for a stream - the issue here lies with third party stream providers, BBC or the other aggregators which just pass on the stream url. 

Historically speaking BBC users, and especially Radio 4 users, seem to be an entitled lot, based on multiple threads on this forum. Of all the issues with streaming the BBC I can recall one that was actually a technical issue with Sonos, all of the others have been root caused to the BBC themselves, or their interactions with their aggregators.

Ok, calling a halt now as resorting to personal insults doesn’t help anyone’s argument.. Thanks to those who have given me helpful responses. I do understand but still hold to the end user view.

What I haven't seen exaplined very clearly here, is the fact that in his “end user view” @amjl appears to conflate TuneIn with Sonos, likely because it is the default option for listening to radio on Sonos.

That is not “end user view”, that is an oversimplification that causes unrealistic expectations. You simply cannot say it does not work on Sonos, because it does - you just have to select one of the many other content providers that Sonos offers access to.

Your comparison to certain channels being available on one brand of TV but not on the others, is flawed, because the restriction is not due to Sonos (the TV) but due to the content provider (TuneIn i.e. “the cable provider”). I expect this behavior is the same on competing systems like Denon and Bluesound. So the correct TV analogy would be that the brand of TV is irrelevant, but you would be able to get the channel you are looking for by switching to another cable provider.

Would you blame Sonos because certain artists are not on Spotify, but are on Tidal, or Apple Music?
