All sounds are stuttering/echoing

Today after installing the 7/12 update, every sound is stuttering, including the music. From footsteps, zombie sounds, to cave sounds. The best way I can describe the effect is a sound happens and then pieces of the sound echo rapidly. Footsteps sound like there's 10 footsteps happening per step, sometimes more. Here is a literal caption of the effect: TNT explodes, boom; then rapidly, boo-boo-boo-oo-oo-oo-oom-oom-mm-mm-mm. The effect is fast and that caption occurred in 1 second. This has only ever happened immediately loading a world after the update. No other games have this effect, ps4 regularly gets defragged. Minecraft was uninstalled and reinstalled. Problem still persists. Thank you.
