Remote audio devices not discovered

Roon Core Machine

i7-4790 8-cores 3.6GHz 12GB RAM
Ubuntu 20.04.3 LTS 64-bit

Networking Gear & Setup Details

Unifi DreamMachine (Network 6.5.55 / System 1.10.4) using Ethernet

Connected Audio Devices

iPad-Pro 9.7
6 Sonos devices (4 roon-tested)
Devialet 220Pro (roon-ready)
Windows 11-Home PC (Ryzen 9 3900XT, 32GB RAM) with 2 audio devices connected via USB: AudioQuest DragonFly Cobalt & Aune X8 Magic Dac

Number of Tracks in Library

Description of Issue

I installed RoonServer on my Ubuntu server.
Once done, I’m able to connect to RoonServer from my iPad, login, add tracks and play some music from RoonServer to the iPad.
All Sonos devices are also discovered.

However, when I install Roon on my Windows 11 PC, the 2 connected devices (DragonFly and Aune X8) are not discovered by the remote RoonServer.

I have done some investigations but nothing.

RoonServer and Roon running on Win11 PC are the same version: 1.8 (build 882)

They run on the same subnet

RoonServer:
Roon on PC

Roon running on PC successfully discovered the 2 connected USB devices

but the RoonServer never receives the “broadcast” of this discovery so the 2 devices don’t appear in the list of available audio renderers.

The only issue that I see is in the RAAT log on the Windows11 PC

Thanks for your help

Good job with your investigation. I suspect this is a firewall issue. Perhaps try disabling the Windows firewall and then restart Roon.

Also, why are you running Roon Server on your Windows 11 PC? You only need one copy of Roon Server running on your network. If you have a DAC connected to your Windows 11 PC that you want to use as an Output, I’d suggest uninstalling Roon Server and replacing it with Roon Bridge.

You can run Roon Bridge alongside the Roon desktop UI (functioning as a Control), but don’t mix Roon Server and Roon Bridge on the same machine. That’s like crossing the streams in Ghostbusters. Not pretty.

I hope this helps!

Thanks.

I have uninstalled Roon on my Windows PC, rebooted, installed RoonBridge and it did not help.

All my FW are disabled,

on Windows PC
and on the Linux machine of RoonServer

I suspect an issue with broadcasting of devices from my RoonBridge Windows11 to the RoonServer running on Ubuntu.

I have re-installed from scratch RoonBridge on Windows11, everything seems normal at startup.
No error on logs (RAAT and Bridge) and the USB connected devices are detected in RAAT and broadcasted OK over the network at 13:59:38 on port 9200:

I have checked the TCP connections on the RoonBridge Windows11 PC, where everything seems “OK”.
There is (only) 1 TCP connection (ESTABLISHED) to the RoonServer with port 9332

TCP 192.168.1.21:50938 PC-MULTIMEDIA:9332 ESTABLISHED [Roon.exe]

So in short, everything seems ok for my untrained eyes but still I cannot get the USB devices remotely connected.
Any clue? Thanks

I tried something else today.

I could get my hands on a new Windows10 PC, on which I installed RoonServer in place of the RoonServer that was running on Ubuntu 20.

And everything is running perfectly: The Win10 RoonServer can see the USB audio devices attached on my Win11 PC

Which means that:

There are no problems on the Win10 PC: Roon and Windows firewall
The are no problems on my network (router, LAN setup, etc.)
The problem is somewhere on the RoonServer installed on Ubuntu20, but where ?

Still investigating …

EricWa · December 23, 2021, 3:53pm

As I couldn’t figure out the source of the problem, I went for a ‘Reset this PC’ aggressive plan on my Windows11 PC.
And it fixed the issue

I don’t know what was wrong on this PC, maybe after I upgraded from Win10 to Win11, who knows…

Good thing is I can enjoy the full Roon experience in my house now !
