Description of Issue
Roon server appears to be working fine
Roon installed on M1 Mac - all works fine - local audio devices show and Naim Uniti shows - all works as expected
Roon installed on Windows 11 machine - no local audio devices present. Streaming to Uniti or other external audio devices is fine. Also tried a fresh install of windows 10 - same issue.
I am an IT consultant and confident I have created all the necessary firewall rules etc and the LAN is functions (besides, the Mac works fine).
RAAT logs on the Windows PC shows that it sees its own audio devices:
Iâm so sorry for the delay in getting back to you⌠we just got back to work after the weekend.
Thanks for sharing the issue you ran into, as well as the steps youâve already tried. Weâve seen Windowsâ automatic updates negatively impact the way graphics drivers work with Roon, so, I was wondering if youâd be able to:
restart your Windows
unsintall the graphics drivers
navigate to the manufacturerâs website and download the graphics directly from there
This trial coincided with me rebuilding my machine a couple of time. So I have tested on three separate installs:
Windows 11 - Insider preview
Windows 10 - fresh install from Dell factory image
Windows 11 - post upgrade from install above
All exhibit the same issue. All have been fully updated with drivers etc.
Ive done some extensive testing. It appears that when launching Roon client on Windows, it makes a connection to RoonServer. That then makes a connection back to the RAATServer that is running on the Windows machine on port 9200. It appears that this connection is failing. Netstat on the Roon server shows the connection in a SYN_SENT state (meaning its not able to connect).
I have disabled all firewalls and the issue is the same. I have also run a network trace via Wireshark on the Windows client and I can see the incoming SYN request from the Roon server (this rules out any network or firewall issue, as it shows the traffic is arriving). However there is no response to the connection request. I have tried running Roon âAs Administratorâ and this hasnt helped either.
I am having what appears a similar problem after installing Windows 11. My Bluos players are fine using the Bluos App but in Roon the Powernode 21 is showing as Roon Ready but the Pulseflex is not. When the Pulseflex does play with Roon the sound suffers from severe crackling.
Thanks for reaching out and for providing those details!
Just to confirm here, these were all on the same PC?
We have sometimes had issues with Realtek ASIO drivers and Roon. If you try to install the Realtek drivers via Device Manager and let Windows install the default audio drivers, is there any change?
Is there anything else that is using port 9200 on your machine? In the past weâve had apps like Plex or Emby cause communication issues, but those typically run on port 9100.
Have you tried a fresh install of Roon as well? I have provided steps on how to reinstall Roon fresh below:
Hi
Yes this has all been on the same machine.
I dont use the Realtek device. I have uninstalled the drivers and disabled the devices.
There are no other services using port 9200 and I can confirm via ânetstat -anoâ that port 9200 is bound to the RAATServer process.
I have just reinstalled Roon and see the same issue. Oddly this time though I dont see it start up the RAATServer process at all.
Hi
I have resolved the issue. This was caused by additional security settings applied via my workâs Intune device management service. This was causing the configured firewall exceptions to be ignored, which is why the inbound connections from the Roon Server on port 9200 were being blocked.
Thanks for the update here and for letting us know that the issue was the Intune firewall! Hope you have a continued excellent Roon experience, and please do let us know if we can assist in the future!
