Halo: MCC In Game Audio Settings

Does anyone know if / how to adjust the in game audio settings for Halo: The Master Chief Collection on the Xbox One? The music and sound effects are really loud but the voices when Cortana or another NPC speaks in game are very low. I know with most other games you can adjust the ratio or at the very least lower the sound effects and music volume but I can’t seem to find that anywhere in the settings. This seems to be the issue with all four games as they all seem to share the settings menu. Any help is appreciated. Thanks!
