I keep getting a Bad directsound driver, Error code: 8878000A. In the device manager the "multimedia audio controller" under "other devices" is yellow flagged. I've tried to reinstall the driver but it is not found within my system and I don't have it saved anywhere nor do I have the original cd. Do I need this driver; since it is listed under "other devices" would it be an option to delete it? Should I delete it and reinstall it?
