so when i first got my computer i was playing around and accidentally deleted my sound and now when i clicked it there's a red x by it and and it says "detecting problem playing sound" and it says i need headphones or speakers. i tried going to settings to try and fix it but, it wont let me click start up and the only options are disable. Can someone please help me 🙁 (i have a dell's windows 10 computer by the way)
