I have been using Audirvana for Windows for quite some time, and it recognized my ultra rendu as the player. Within the last two weeks, however, AW will not connect to the rendu, but rather only lists WASAPI or ASIO outputs. I have tried AW 1.3.7 and 1.3.8 to no avail. Roon does recognize the ultra rendu (thru the Roonready connection on the rendu), but the UPnP/DLNA does not work for AW. Any suggestions?
