@Zing thank you so much for your time and help. I've ended up going for a new install again. I cannot say for sure what caused the issue, however after a clean install everything went back to normal.
@substring Yeah, no problem, I just wanted to keep it at max anyway. I just thought that the games had no sound since one of my cables from my TV to my sound system had become unplugged. In-app volume settings are probably only necessary on hand-held/arcade devices anyway. Thanks for the help.
