If you're seeing no-sound on your PlayStation 4 / 5, the steps below walk you through the most common fixes.
If there is no audio, first check if other apps have sound. If they do, check the Hulu/Disney+ audio settings (some shows default to "Surround Sound" which your TV may not support). Switching the audio track to "Stereo" or "English" usually restores sound.
