I'v recently gotten a pc with asus m5a97 le r2.0 mobo but there is no sound coming from it. when i plug in earphones i get sound but there is none coming from the pc. my pc is connected with VGA cables and i understand that VGA doesnt have sound but my old pc , there would be sound coming from the pc.. i checked the sound settings and it shows green bar for sound levels but its not coming out . Any ways to fix would be much appreciated
