No Sounds at All in Wings of Liberty Campaign

Whenever I try to play the Wings of Liberty campaign there is no sound. No music, voicelines, or sound effects during gameplay, loading screens, or cutscenes. Changing audio device does nothing, nor resetting audio settings to default. Restarting the client does nothing.
All of the other Starcraft II menus in the client have full sound working. Only the campaign has no sound. Even after 5+ missions the bug hasn’t fixed. I don’t know what to do, I kind of rely on sound ques sometimes and its making the gameplay a little frustrating/boring.
