All sound only coming from earpiece

Hello there, so I recently noticed that any and all sounds coming from my iPhone 8 when I play videos, run apps of any sort or just listen to any form of audio, come out exclusively from my ear piece- the one speaker that’s beside the front facing camera-, while the two bottom speakers- the ones to the left and to the right of the power socket- don’t seem to work at all. Therefore I was wondering how I could resolve this issue, if at all- I’ve already tried to balance the audio channels through the accessibility settings btw.
