Games Not Playing Music Or Cutscenes

[infiniteintricacy]

So i've been kinda reluctant to install CFW on my PSP to extract UMDs as ISOs cuz of possibly bricking and ruining psp, plus i generally like the vanilla OS. so i downloaded an isos of games i own and the cutscenes and background music doesnt work. Namely Daxter when you start a new game just goes right to the you running around out front of the bug store and when you talk to the guy, it skips the dialogue and goes onto the next part.

Basically, im wondering if i turned on a setting, or if i need another plugin, or if its just a bad file and i need to make one myself.
