No Sound In Media

I have a Samsung Galaxy J2 Pure. I recently dropped on phone on soup while it was on, screen side facing up. Naturally, I frantically started to wipe it clean. I got the screen cleaned up and proceeded to address the backside of it.

The problem lies where it does sound when I get notifications or it rings. However, it does not have sound when I try to play Youtube or Facebook videos. I tried cleaning up the speaker. It sounds fine in notifications. But absolutely nothing when in any other apps. I restarted my device twice already. “Do Not Disturb” is not on. All volumes are maxed out.

Please help. I cannot afford a new phone or replacing parts right now.
