Running a jukebox

Ok so I was looking for some means to control a media player on Computer A (the one connected to the stereo sound system and speakers) from my laptop (Computer B).
I though Subsonic sounded ideal as it uses a browser based control so it makes it easy to connect to. Great. Installed it through the windows installer on Computer A and was able to connect to it from Computer B.
The problem I have is that since this is a streaming app the sound comes out of the client (Computer B) rather than the stereo (Computer A).
Is there a way to use the front end (the browser control) on Computer B to control the music played on Computer A, that is so the sound output comes out of the speakers attached to Computer A.
I don't want to stream, I want to just control a Jukebox from another machine. Streaming might be useful in some situations but not in this one.
I have tried playing with the "players" but they reset all the time and try and stream or if I manage to get a player streaming to the localhost on Computer A the Stop button doesn't work on the client (Computer B)
Is there a way to do what I want to do as the UI on this is great?
