DLNA - Beginner's question

I have an Audiolinux server running Roon & HQPlayerEmbedded 4.0.

I have installed demo version of Audirvana on mu Windows 10 Pro PC. It basically works, I can play music locally, and I can configure WASAPI and ASIO DAC connections.

I would like to test Audirvana + HQPlayer. I therefore have stopped my Audioserver, restarted and only restarted HQPlayer on it.

Based on the little information I found, I had hoped that Audirvana would be able to detect HQPlayer automatically via DLNA.
But this is clearly not the case.

Can someone provide me with the (some) steps that I need to make in order to make this detection feasible?

Thanks in advance for your support
