check that you set your driver setting for 5.1 and check the connection according to manual of speakers.after all setting run the test sound from driver setting panel.if now still no sound there may be problem in hardware..

Well, just check for driver that it is compatible with windows 7 .use update driver there is some sound related bug for windows vista .
