I have the same issue with KEF LS50 Wireless. It doesn’t matter if I’m running on WiFi nor on ethernet. I have several other Roon devices but they never loose their connection (Naim, ProJect).
Restart of the entire system solves the problem but it will loose the connection after a while.
- Select the KEF as source. This is succesful in the KEF unit (it selects the new input).
- But the Roon GUI reply that ‘Roon lost control over the audio device’.
I have the latest versions of both Roon and KEF software so that doesn’t help the issue.
