IPhone 8's sound/volume issue?

My iPhone for some reason this morning decided to act strangely. Whenever I watch a video on YouTube or play music I can barely hear any audio even when the volume is turned all the way up. The audio is very faint and low I can still hear whatever video or song I'm listening too but it's extremely low. If anyone knows a fix or solution to this issue please let me know! The earbuds are not plugged in either.

Speaker might get wet if you used it one time in bathroom. Or because its sound amplifier became defective.
