I'm not at home at the moment to check whether a DNLA zone is implemented, but I wouldn't have voluntarily done that.
Yesterday evening I uninstalled the program, rebooted, then reinstalled. In Windows Control Panel sounds, I checked that the NAD driver was being used NAD SPDIF (USB Audio) as opposed to NAD speakers (weird option). I made sure NAD ASIO was the input and checked windows exclusive mode was checked.
No boxes are checked in the DSP window. Nothing shows up on audio path. I tried every mode, WASABI, DIRECT, all of them but no audio paths are displayed and of course no blue box.
I greatly dislike LiTunes. The library implementation is just plain silly.
JRiver is logical and want to make this work!
