Im having problems with far cry 4 with 5.1 audio. If I use my mobo (Z97 pro wifi ac) audio which is 5.1 connected to a 5.1 surround sound I get no sound after the intro. But if I switch my default audio to my gpu (r9 290x) I get sound. But using the gpu I can only get the sound to my tv speakers. Is there any fix/patch for this or am I stuck with 2 channel audio
