Description of Issue

I can see my Roon Bridge in Settings/About.

I don't see any devices under Audio for RoonBRidge.

When checking on BeagleBoard I can see RoonBridge active and my USB DAC is a default audio device.
What can I do to make it visible under Settings->Audio in Roon?

Log files for RoonBridge are clean

Can someone from Roonlabs support give me a hint what to do next?
Is there some known generic issue about using Beaglebone Black as roon endpoint with Roon Brigde?
I have tested the USB DAC, and it shows up if I connect it directly from Roon Core machine.
Roon Bridge is visible in Settings->About. However no audio devices are visible under Settings->Audio for RoonBridge when same USB DAC is connected.
I have even upgraded to Ubuntu 18.04 on my Beaglebone but the issue is exactly the same. RoonBridge visible, but no audio devices available.
I will be truly thankful for some help.
There is only one audio device connected to my Beaglebone:

Hey, @JSA23 we’re so sorry that it took us time to respond to the issue you’re experiencing - it certainly was not our intention!

We wanted to check in and see if you were still having trouble with this?


I have this exact same issue. My BBB is running DietPi, scaled down from a clean Debian Bullseye installation. I see the BBB in the “About” section under Settings, but I don’t see the BBB or my USB-connected Topping E30 in the “Audio” section. However, I do see the BBB listed as an Airplay device (I also installed Shairplay in DietPi).
