First I would like to apologize to 343 if i made them more frustrated about the audio issues in Halo: MCC. If You Spartans can’t hear the cutscenes and in game dialogs in all the Halo Campaign and also the Audio Issue in Halo Nightfall, Just Simply go to Settings, then Display and sound, then select HDMI input and select Stereo, the second setting should be Bitstream out and the last Sound option to Dolby Digital if it’s possible on your TV, I Hope this Helps, if it doesn’t message me and i’ll try out another way, if Possible, Thankx!
