Can't play from grouped Airplay device any longer

@support: Since a few weeks (before 1.6) I have the problem, that If I group my two airplay devices, playing music failed. It isn’t playing anything and after a few seconds the play button changes from pause back to the play symbol. Then one of the devices is not longer accessible and had to be rebooted.

Each of the device have no problem playing alone.
Problem started without any (known) changes in my whole setup.
In the meantime both devices had a firmware update an Roon update to 1.6 with no change.
Devices are Yamaha RN602 and Libratone Zipp.

Here is the log from the last incident.

@support
Any ideas? I miss my grouped zones each weekend :slight_smile:

Hello @AE67,

We apologize for not getting back to you sooner. Your report was added to a ticket tracking some grouped zone playback issues with Airplay 2 devices, but the initial response was never sent unfortunately.

We are tracking this issue and hope to be able to make some changes to alleviate the bad behavior. I cannot say for sure when these changes will be made, but active work is being done in area with the help of a few partners. I will be sure to reach out when this work has been completed.

Tried it with new version.
Sorry, but problem exists already with build 401.

@john Any update on this problem?

Hello @AE67,

We have continued to iterate on our Airplay implementation in the last few updates, but it’s becoming clear that we will not be able to get this resolved without some further assistance from the device manufacturers.

We’re going to reach out to Libratone in a technical capacity, I will be sure to let you know when we have received some concrete information to work on.

In the meantime, it would be helpful to confirm with certainty that this setup is working as expected using iTunes. Could you let us know what the behavior of your system is when you attempt to group the Yamaha RN602 and Libratone Zipp using iTunes?

-John

Hello @John,
I have no problem using both devices grouped in iTunes.
And it also worked with Roon for more than a year. I cannot say on which day the problem started, it could be after updating to Roon 1.5 Build 363, but I am not sure.
