I recently reinstalled sound max driver 22.214.171.12410 after the XP OS was reinstalled. I have an ASUS p4p100 motherboard. The device driver says the driver is installed - no exclamation points; no question marks. The tool bar at the bottom says it is "there". All volume controls are "on" and speakers are plugged in. Still, no sound. Any other suggestions? I have uninstalled and reinstalled twice. I have run virus scans and it says the file is signed with a broken digital signature. Thanks.
