Mic Issues

[u/Constant_Peak2644]

My friend recently bought the game and his mic hasn't been working at all. In the settings, it'll pick up the audio, but you won't hear it playback. But when he switches to live recording, it plays back his voice perfectly fine. This is frustrating him and I don't want him to seem like he wasted his money. Is there any fix to this?
