Does not find play back device

I can not redirect the playback to by Denon 3808 AMP (latest firmware). While other apps can redirect (8Player e.g. ).

Why does this software not find it?

Alles other handling is perfect. Best App. in store (ive tried them all). But without better identification of Playback and maybe Serverdevices, this is useless.

I will keep an eye and update this if there is progress.
