Description Of Issue

I just switched the Roon core from an aging Surface Pro4 to this new laptop with same network setup.

I was having periodical connection issue with Surface Pro, same “Roon lost control of audio device”, which I would fix by restarting Roon, and/or the speakers and/or turning the TP-Link off and back on, not always successfully.

I was hoping the problem was because of old Surface Pro but no such luck: I haven’t been able to run Roon from new Lenovo at all yet: I get the “Roon lost control…” every way I tried: playing music from Tidal, or from music stored in Lenovo.
I tried resetting the KEF, no progress.
The speakers show up on Roon, and are turned on when starting a new song, but just don’t play.
The speakers work normally with the KEF app on tablet and phone using the same wifi network.

Help! Thanks,
Bernard

Hello @Bernard_Rene, is your core connected via Ethernet? Do you have any issue streaming outside of Roon to this device?

Hi @nuwriy , the laptop is wired with ethernet to the access point. The speakers are connected wirelessly to the same access point and its KEF app on my phone works normally.
Something else strange is that the Roon remote app cannot connect to the core, in neither my phone nor a tablet, though all are connected to same network (access point)

I figured it out: it was the public firewall. Not the private one, which I had thought to turn off, but the public one, which I don’t understand. But I’m all set.

But if someone knows how to put an exception for Roon in the MS Defender firewall so that I can turn it back on while letting Roon play, I’d appreciate it.

Hello @Bernard_Rene, you’ll want to make program-level exceptions for both Roon and RAAT.

Got it, thank you! (Maybe put that in installation instructions?)
