When I start up my computer I can hear sound, but when I start up World of Warcraft the sound goes away. However, I can still hear some sounds (error messages, etc...) When I click the volume tool it says: There are no active mixer devices available. To install mixer devices, go to Control Panel, click Printers and Other Hardware, and then click Add Hardware.
