How can I test my sound card using the DirectX Diagnostic Tool?
After installing DirectX 9.0c, you can run the DirectX Diagnostics program to test your sound card. To do this:
Select Help from the Star Wars Battlefront launcher.
Select Analyze Your Computer.
Click on DirectX Diagnostics. This takes you to the DirectX Diagnostics screen.
Click the tab that says Sound, and then click on Test. If your card fails these tests, you may have problems running Star Wars Battlefront or any other program that requires DirectX.
