Fortnite has no sound at all. Other games using the Unreal Engine (Steam games like The Invisible Hours, Sprint Vector, or Rad Rodgers) all have the same issue.
I have tried reinstalling my Realtek sound drivers (currently v10.0.17134.1 from 4/11/2018 from Microsoft), but it didn’t fix anything. Up until about 4 months ago, Fortnite (and my other games) had sound. All other non-Unreal games work flawlessly.
I’ve tried using headphones and other speakers, and have not had any luck. Any suggestions?
