Why is my audio distorted and low pitched?

[I need k8 help]

I have an LG K8 V and today the audio for everything randomly distorted and is lower pitched. This happens in Safe Mode too. How do I fix this?

Moved from the Audio/Video forum to the More LG Phones forum (since the former is intended for standalone A/V equipment).

Is the audio also distorted when listening through wired or Bluetooth headphones?
