Roon not working with WASAPI device via Windows 10 client (Metric Halo ULN-2 3d)

Description Of Issue

I have the ULN-2 connected via USB to a Windows 10 (Build 19041) client and Roon shows two WSAPI devices (and “System Output”), one for the ULN-2 and a second for “AMD High Definition Audio Device”. The latter, which plays audio through my monitor works great via Roon, if selected. However, I’m unable to use the ULN-2 via Roon. Also, I can use the ULN-2 to play through a browser (stream from the radio) or other non-Roon applications. I have lots of other clients that work fine, just trying to add this new client.

Can you help troubleshoot my issue?


It looks like I’m getting RAAT__OUTPUT_PLUGIN_STATUS_FORMAT_NOT_SUPPORTED in my logs.
