If you're seeing no-sound on your Chromecast, 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.
