Hello Tiki,
Today I installed Audiophile UPnP Renderer (v2.3) to perform some UPnP testing:
https://sourceforge.net/projects/audiophilerenderer/files/Setup/
However, I found that TuneBrowser does not seem to work correctly with Audiophile UPnP Renderer, and playback cannot be started successfully.
In contrast, the same renderer works properly when used with foobar2000.
Could you please help confirm or take a look at this behavior?
Thank you very much for your excellent development.
