Fails to play any music then can't find playback devices

(Ad Q) #1

Just started a free trial to see if it’s worth the ongoing fees. Roon successfully finds all playback devices on the first run but fails to play any of my music. Rebooted. Now Roon can’t find any of my playback devices: motherboard audio, usb connected headphones, usb connected pioneer dj turntables with connected headphones.

64 bit windows 10. would upload a dxdiag file to help the support team diagnose issue if there was a way to attach files to this?

the uploaded screen shot shows what appears for 2-3 seconds when I click on the “No Audio Devices Found. Manage Audio Devices” button at the bottom of screen. The list of devices disappears after 2-3 seconds and then blank. All devices are connected. I can listen to music through all devices using other programs.

Hello @Ad_Q,

Thanks for contacting us regarding this issue. Can I please ask if you have any firewalls in place that could be blocking Roon? I would suggest that you take a look at these instructions to make sure that Roon is listed as an exception. If you have any antivirus software, it would be good to verify if the same issue occurs with it temporarily disabled, as then we would know to take a closer look at that firewall. I would also try rebooting your Core machine afterwards. Please let me know if that helps.

Hi Noris,

Thanks for your reply. Roon.exe was (and still is) listed as an exception for public and private in the windows firewall. I only have Windows built in firewall and antivirus.

Hello @Ad_Q,

Apologies for the delay in getting back to you due to the holiday season. Have you made sure that RAATServer is also listed as an exception? RAATServer should be listed as an exception there as well for local endpoints to work. I would also reboot your Core if you have not done so yet, please let me know if that helps.

Hello @Ad_Q,

Eric told me that you are still experiencing some difficulties here, can I please ask you to provide the full topology of your network? Please be sure to include the model/manufacturer of your Router, any switches, range extenders, powerline adapters, ect.

I would also double check to make sure that both Roon and RAATServer are listed as exceptions to any firewalls or Antivirus software you may have (Bullguard, Little Snitch, McAFee, ect). Please let me know if that helps.

Hi Norris.

It’s very simple. I have Room installed on my Windows 10 PC and I’m wanting to play music on the speakers connected to the motherboard, a pair of USB connected headphones and a seperate pair of headphones via a Pioneer DDJ-SX2 DJ deck connected to the PC via USB. I Have music stored on WD EX-4100 NAS and music stored on a local drive on the PC. The router connecting the NAS to the PC is Netgear DGND3700v2.

I only use the firewall and antivirus that comes with windows 10 pro. Everything is listed as an exception in Windows firewall.

Did you list the programs or open a range of ports in the firewall?

Thanks for letting me know that info @Ad_Q,

I would suggest double checking the firewall to make sure that the program Roon is listed as an exception and not just specific ports.

We can also try to see if generating a fresh RAATServer on your Core helps. To do so follow these instructions, but please be aware that this will reset your Roon Settings -> Audio Tab to factory settings and I would advise making a backup of any custom DSP settings you have first:

  • Exit out of Roon
  • Navigate to your Roon’s Database Location:
  • Find the folder that says “RAATServer”
  • Rename the “RAATServer” folder to “RAATServer_old”
  • Restart the Roon App to generate a new RAATServer folder

Please let me know if that helps.

Just have a go at temporarily disabling the windows firewall and see if the devices appeared. My W10 system has just started doing the same thing, connections appeared once disabled.
Also have a look at your W10 ethernet network connection and see if it has been shifted under Public Network.

Hello @Ad_Q,

Eric got in touch with me regarding your response via email with the screenshot.
Can you please give part #2 of my instructions a try and let me know if that helps?
