· I am using Roon on Synology NAS, along with DS Audio and Oppo Sonica. Using the Sonica app I created a stereo pair which DS Audio and Sonica recognize. The Roon app and desktop does not, but sees the speakers individually. I can download an additional music app to test.
To clarify first: Roon does not support DLNA control or DLNA grouping. While Roon can expose a DLNA output in a limited “renderer” sense on some devices, features such as DLNA-side stereo pairing or grouping created in third-party apps (like DS Audio or the Oppo Sonica app) are not visible to Roon.
Because of this:
Roon will see the speakers as individual endpoints
Any stereo pair or group created via DLNA apps cannot be discovered or controlled by Roon
This is expected behavior and not a bug
If you’d like stereo or grouped playback within Roon, the supported options are:
RAAT endpoints (Roon Ready / Roon Bridge), or
Device-native grouping systems that Roon explicitly supports (e.g. AirPlay 2, Sonos)
Just to reiterate, there’s no way to natively create a DLNA-based stereo pair/grouped Zone within Roon.
As @vadim suggested, one option is to expose the manufacturer’s own control app to expose the speakers to a protocol Roon supports.
Another option is to place a Bridge that supports RAAT and can also support DLNA. This would not be an official route, but if you search through or create a post in Tinkering, you’ll likely find some possible paths forward with this speaker setup.
We’re going to allow this thread to auto-close, but please do create a post in Roon Software Discussion or Tinkering where topic timers aren’t applied to threads. Thank you!
