Audio problem

[Guest]

I am having a problem with sound that was OK and now it is acting strange. I
can play DVD's and sound is fine, I can play MP3 files stored on computer and
sound is fine. However I have no system sounds, no game sounds i.e. pinball
and for example my son plays a Star Wars game that no longer plays sound. I
have checked all settings. Obviously the sound card is OK.
Anyone have any clue because I do not.

Windows media uses a seperate set of audio files than the OS normally runs,
however,if its a PCI card,power off pc,move the card to a diffrent slot.If
on-board,
try going to run,typeXDIAG Run the Direct X sound tests,and/or,uninstall
all the sound hardware in device mgr (one @ a time),do not restart after
each,
once all are uninstalled,restart pc.XP will reinstall on restart
