sorry for being not very precise on what I want to do. Let me try again: I want to listen to some drm restricted music coming from napster or itunes The only speakers which are worth to be called speakers are connected to a linux box (in my office as well as at home). I don't need any 'noise' coming out of the speakers of my laptop, but my laptop is the only windows computer around. I was already able to get a test setup running but I'm not happy with the network traffic I'm producing: I'm sending the data once via a tcp connection from my laptop pa server to my linux pa server and then the linux server is sending the data once again via rtp to itself. In order to avoid the rtp traffic I'm looking for a way to send data from a pa source to a pa sink. As Colin proposed I'm going to look into gstreamer which seems to allow what I want cheers ulf
