Fortnite no sound (headphones)?

I downloaded fortnite again today but when I go in I already have no sound I have already tested everything the headphones work well can someone help me there and the settings are completely new as there's no plan and on youtube the videos bring nothing.

Where did you download it and are you sure that the headphone connection is correct?

With the Epic games launcher and yes, the connection should be right

You have to activate sound in the sound settings and select the headphones. Then there's a message from the firewall that you have to accept. Then it works. It was the same with me
