What kind of computer do you have? It appears that whoever formatted and loaded the operating system on your new disc forgot to install the necessary audio drivers/codecs compliant with your computer's audio hardware(card or chip). It's also possible that the disc was removed from another computer and then "cleaned up" for re-use.
Depending on what kind of computer and audio card you're using, it is possible to download the necessary drivers and/or codecs from the internet. But, more info is needed.
I just had a new hardrive put in my computer. There is no sound. When I go to the control panel to the sound, it says there is no audio device. Help!!!!! Step by step directions please.
