I have a Sabertooth Z77 mobo and I'm trying to use the onboard audio. I installed the driver from ASUS on Windows 8. When I'm using the ASUS driver program to test the sound, every speaker works individually fine. However, when I try to watch videos on vlc, there's no sound. There's also no sound when I play any videos on chrome, and no sound when I play netflix on Internet explorer. There IS sound when I play videos on Firefox and Internet Explorer. When I plug my head phones into the front jack, the sound always works. I've reinstalled the drivers to no avail. I do have my graphics card hooked up to my monitor via HDMI, but I've gone into the nvidia drivers and disabled the HDMI sound to my monitor through there. Any suggestions? I'm a bit lost here.
