Fortnite Headsets - Talk to People?

I did all the audio in Setup> Output via Headphone>

and on sound and video> Audio output> Audio formats bisstream Dolby

but I still do not hear any talking at Fortnite? What did I do wrong?

You need to turn on '' Voice Chat '' settings in Settings on '' Audio '' then you should hear people on the voice chat. If you ask general about speakers or ingame sounds then I can't help you.
