I'm Justin and I wanted to ask why I have no sound at Fortnite but otherwise everything?
With Windows 10, you can set the sound for each application individually. Start the game and then go back to Windows with Atl + TAB. Then right click on the small speaker icon in the system tray, open the volume mixer, and then you'll see it.
Game settings already checked?
I know, but it does not work!
Otherwise with everything
Let me guess: you're Justin and work in the kebab shop?
Open Fortnite, then open Windows Search and search for "SoundMixer options" (appears when you type "Audio"). Then you open the (Settings) and see if the correct audio device is selected when output under Fortnite.
Right. If it was not my tip, it must be.
