Update:
I have tried everything on the follwing videos to try and fix the sound, but the result is still the same, sound will only play through my headphones and not through my internal speakers.

The only thing I have been unable to try is "restore point" because I try and it only gives me the date of 4/17 (and the audio issues happened on 4/16) :(
