No Sound on Averatec 3150 Laptop



I have no sound on my 3150 Averatec Laptop. But I use to. One day I turned on the computer and the volume icon did not appear in the system tray. I navigated to it in the start menu and when I click on it I get this error message, “There are no active mixer devices available. To install mixer devices go to Control Panel click Printers and other hardware and then click add new hardware. This program will now close.”

I already checked that window’s audio is turned on automatic in the service menu and I tried the trick with the machine.inf file, copying and pasting it into my windows temp folder and it still did not work. Can somebody help me.
