Only Airplay devices do not play music

Dear Support,
I need a little help:
I realized 3 weeks ago (did not use Roon on a daily basis and have a lifetime membership) that my 2 Airplay devices (Marantz MCR-611 Airplay; Bose Soundtouch 10 Airplay2) do not play music from Roon. Devices appear in “Settings/Audio” tab and are “Enabled” (also deleted and re-enabled them 2-3 times). Roon shows their IP address and could be selected as music zone/device when trying to play back. Does not play neither from Tidal nor from own Synology NAS music library. Both Marantz and Bose play Spotify Connect perfectly, so LAN connectivity hopefully has not become the issue. Roon server run on a dedicated Intel NUC with Ubuntu 24.04.3 LTS natively, not in Docker. Intel NUC runs Plex and Immich with no issue too. Earlier Airplay devices were playing without a problem in this setup.
The Roon version on Ubuntu server is 2.56 (build 1582) production.
My NUC setup is:
Intel(R) Core™ i7-7567U CPU @ 3.50GHz
32 GB DDR3 RAM
Everything is connected by Ethernet through Synology MR2200ac router

My Samsung Ultra plays from Roon without a problem both Tidal or own library albums/songs. Also RoonArc is available and plays well on my Samsung from WAN, so Roon server seems to be working just fine.
What should I check in order to get Airplay devices working again with Roon? Sorry if a long-existing topic would already answered this question, I tried, but did not find a proper answer/solution for this.
Thanks for spending time for reading and sharing your insights, thoughts.

Hello @Gabor_Piller

Thank you for reaching Roon support.

Can you try clearing your endpoint cache? You can do so using the following steps:

Note: Deleting these files will

  • Log you out of Tidal/Qobuz
  • Delete your endpoint names.
  • Delete saved DSP configs.

If this doesn’t help, please restore the backup you made before trying these steps.

After performing the cleanup, please let us know the exact timestamp of the playback for one of the devices and when you will enable the device again under Roon → Settings → Audio

Thanks @vadim, I’ll try these and get back to you. Hope it’ll work.

Certainly let us know how the above goes @Gabor_Piller - we’ll be monitoring for your reply. Thank you! :raising_hands:

Dear Benjamin and Vadim,
I deleted all files from the Core directory. I stopped and restarted Roonserver on Linux. It remained the same unfortunately. I needed to reconnect and rename the two Airplay devices. (Time: 23:13 GMT+1 timezone) Those can be selected, sometimes it plays starts counting the seconds played, but no sound is coming out of the Marantz. Same unfortunately with Bose Soundtouch. Sometimes it even did not start showing progress of the song. Strange thing that Marantz even displays “Airplay”, but absolutely silent. In the meantime Windows PC plays Tidal through Roon without delay and problem. Samsung phone plays Roon content easily. No real change except I needed to reconnect audio devices and rename those.
I restored the last backup, but unfortunately no change. Yet…
PS.: My Ipad works without a problem as a Roon player, but I suspect, it is not Airplay.

Hello @Gabor_Piller ,

Can you please navigate to the Device Setup tab for the affected Airplay zone (right click zone name in Roon app, bottom right → Device Setup), then go to Advanced, and check to see if Compatability Mode makes any difference?

Hi Noris,
It was already on (Compatibility Mode) It still plays Spotify as an Airplay device with sound, but Roon first started playing (the counter moved), but without sound. Then after trying without Compatibility mode even it did not started and the Marantz display lost the Airplay sign (disappeared).


Roon still plays perfect on Windows PC.
Restarted the Linux machine, Roon is available, plays on Windows PC, but Airplay devices did not show up for 3 minutes. After 3 min, they re-appeared, playing started, but no sound again.

Thanks for that @Gabor_Piller,

As another test, if you set one of the airplay devices as the system output of one of your Roon remotes, and then set your Roon playback zone to your system output - do you get proper playback?

Thank you! :raising_hands:

I tested with my IPad and did what you suggested, it works that way with quite a responsive way. So the IPad Airplay output became the Mararantz MCR611 and started to play in Roon on the Ipad device, it works with sound both with Tidal and radio stations as well as with own NAS library songs. Even plays DSD media files converted to Airplay format.
That way Bose Soundtouch 10 works too.
I am checking now the Ubuntu media-server firewall, etc. 'll get back to you after that.

Checked Ubuntu firewall settings, all ports needed for Roon are allowed:

Avahi daemon is running, so mDNS service is OK on the Ubuntu.
Is there any other port that needed to be allowed?
