Having the same issue, Absolute radio on Tunein will play on first gen Show, first gen dot, dot 3 but not first gen Echo...was ripping my hair out as Amazon music plays to the whole group whether I issue a voice command or cast from my phone. Hopefully the fix will come soon, any news?
I was going crazy cause I had the same issue for over a month now and I thought I was the only one. Today I started looking for the issue online and found this post. Im so happy that I'm not alone. Did all of the things everyone's mentioned, no luck. But reading your answers I realised that I was only trying to play my favourite radio station (Love radio 97.5 - Greece) on the Everywhere group (2 dots 2nd gen, 1 echo 1st gen) but NOT any other radio stations. Seems that some of the radio stations share the same issue but other play just fine. So I don't really know what to do here. Maybe switch to another radio app?
I dont know whether this helps... but I have had a number of issues with multi room music in the last few weeks.
Its been pretty flawless up to recently - but I have found a couple of issues.
Firstly, a single echo device simply remained silent in the group when listening to something (note, this applies to all audio, from tune in or amazon music). The echo itself was working in all other respects and took the command for 'listen to xxxx everywhere' but then refused to play. The solution to this was to power cycle the individual echo and all was well.
Secondly, and far more annoyingly, the entire system went silent. I have 9 echos that form my multi room setup - and they all decided to go silent with all audio (tune in and amazon music). All echos continued to function as normal apart from grouped music output. If I tried to listen to an individual speaker then that was OK, but as soon as I asked for it in a group, it was silent. Annoyingly in a house of 9 echos... my only solution was to power cycle all the echos. This fixed things.
So, the moral of this story is that the good old "turn it off and back on again" seems to clear any issues - but for sure there is a behind the scenes software bug that has been introduced recently that has created this annoying instability. I hope that Amazon fixes it.
In case support find this page or it helps anyone else pairing a new sub.
I just spent 2 hours pairing my new sub.
The problem seems to be Gen 1 alexa devices in any speaker group whilst playing certain sources.
My gen1 alexa paired to my sub fine. But when i played Virgin Radio back via Tune In skill only sub came on.
2 hours of trouble shooting i assumed this was a gen 1 compatabilty issue so paired the sub with a gen 2 device i had having moved and renamed all the devices to accomodate.
gen2 alexa and sub worked fine on Virgin Radio.
I started to rebuild my multiroom groups and found that none of my Gen1 devices will play the radio stream in a mutli speaker setup. They still respond to the group and control play pause but wont output the stream audio.
As per our call I just wanted to bring into your attention that radio is is not supported on Multiroom.
Amazon had better change their advertising then. Multiroom/TuneIn is explicitly described as a feature. What he may have got confused with is Skills can't access multiroom. So if you are using a radio station's skill it can't play on a speaker group.
This won't be the first time that what the support guys say does not match what's on the website
Yes, in my experience the support guys weren't very helpful in my communications with them on this issue. When I told them I couldn't now play virgin radio uk or scala radio on the multi room in group but have done previously I was sent a long email about how the BBC radio stations were not supported on tune-in and multi room radio is not supported for skills.
Everything seems to be working again with speaker groups involving these stations after my First Gen Echos upgraded to 649598720 software.
Just in time for Xmas , Happy again :-)
As a little experiment, one of my echo gen1s had updated itself automatically, the other hadn’t. Quick test and the updated one joined in with his younger gen2 in a group. Older software gen1 = same issue. Told that one to update itself. Once completed, they all played nicely with each other.
I am getting the ‘planet rock is unavailable’ too often via tunein lately. The planet rock skill works fine, but sadly no multi room for skills.
