Seriously? So it is just you recently installed a new gfx driver or windows update that switched the default sound device. Uh... this is not a Fortnite bug, this is not a windows bug, this is not even a bug. If your sound is set to your monitor and sound is off, you will have no sound. If it is set to your rear behind and your butt has no bluetooth it will also not work. PICNIC problems.
I installed that game last nite now my sound doesn't work it says I have NO hardware installed now. ah heck that.
One or more audio services not running... im gonna restart but it IS game related because worked fine before I installed this game last night
