Hi,
I use the SonoreUPnP Bridge, which presents to Roon as a squeezelite implementation, and therefore I am unable to assign it appropriate line-art etc.
I have a feature request here - Device identification for Squeezelite product
I also have had a couple of discussion with @mike about this and understand this is addressed in the next release.
Moderator edit.
Fingers crossed for the next release.
Simon.
