I've tried everything I know how to do, I've uninstalled and reinstalled, I've messed with the sound properties and configuration settings. I just don't know what to do at this point. What happens exactly is that it acts as if it is installed but there is no audio, and when I click on the audio device properties, it doesn't show the jumping line, so the driver is installed but no audio coming in or out what so ever, and it allows the song or media file to play like this.
