dsf to wav : what CPU power ?

I don't know whether BubbleUPnP Server is making a difference to what MIME types are advertised. You could check this with Bubbleguuum.

In order for this to work correctly, both the control point and the renderer need to do the right thing. Kinsky is definitely doing the right thing, so it seems that the renderer (or perhaps BubbleUPnP Server) is not doing the right thing.
