Hi @AndyJ
It works for me with Windows Media Player but I haven’t really used it beyond testing several months ago. See Image “Lounge Speakers” are an “Arylic V3 PRO” hard wired on LAN:-
I am also pretty sure it worked with VLC Media Player, I will need to test again and check my notes. Theoretically the Arylic products are “DLNA Media Renderers” and “Windows Media Player” & “VLC Media Player” should be capable of streaming to a compliant “DLNA Media Renderer”.
I would start with checking what UPnP/DLNA services that your PC can see on the network.
Following this post might help shed some light on your situation.
Kind Regards, Kevin
