Load the game up goto MY RUGBY/SYSTEM SETTINGS/JUKEBOX and make sure they are all or some that you want or dont want are ticked? then click BACK, Click on SOUND make sure your sound is at a reasonable level half-way is good, then save that settings it should work for you then when the next track is played! if this does not work try updating your DirectX this handles you GFX and Sound the latest one is DirectX 9.0c
Too find out what version you have do this, Click on START then click on RUN type in the prompt box dxdiag once you have done that directx will open and test commponents it will give you all your systems info the version will be on the bottom of all the text displayed at the centre of the window.
