My computer says there is no audio device. When I click on SigmaTel Audio it says that "SigmaTel Audio Driver is Inaccessible" "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)". I might've accidentally uninstalled it, I don't anything about computers. Is it possible to download a new driver from the internet or something? or how do I get my audio working?
