SideWinder Game Voice cannot run properly

Hi,
For 2 days when I want to start SideWinder Game I have this error message and it says something about an internal error. I don’t have any experience with this kind of errors and I don’t know how to fix it. Does anyone have any idea what is this all about ? How can I fix this ?
Thank you !

SideWinder Game Voice can’t start because the Sound Hardware Test Wizard did not complete successfully. SideWinder Game Voice cannot run until this problem is resolved. The next time SideWinder Game Voice is run, the wizard will be launched.
OK
