I have a RP4 with RopieeeXL which has both Airplay and DLNA and it feeds my DAC.
In the past I was able to connect via DLNA but I just moved my music to a NAS Server, and started JRiver with a brand new library and thus lost a lot of my settings.
I have the DLNA set up with all three boxes checked (renderer, controller, server) and I'm using Generic DLNA but it doesn't show up under Player.
I must be doing something wrong but I can't find it.
