Answer #1
i had same problem
go to taskbar far right and right click on the speaker icon
Select playback device and make sure your audio driver is selected for playback and not your headphones
failing that – right click on My computer then Properties and then device Manager and make sure your audio drivers are loaded correctly and u got no errors in there
if u need updated drivers etc then use this program as its the one i used after fresh install of win 10
