My xbox has sound. Once I click past message of the day, halo goes mute, but my xbox has sound, I can hear the halo music until after message of the day??? Never had this issue before, I use a headset I don’t have speakers.
I fixed it… Forgot I turned off the effects in game while on Pandora last night…such a rookie mistake…
