A. Go to your device's main settings, then navigate to 'Sound' or 'Volume' settings. Adjust the media volume and check if the voice-over volume can be adjusted separately. If not, try lowering the overall media volume while using the app.

B. If the app has a volume control within its settings, adjust the voice-over volume there. If it doesn't, consider using headphones with volume control to manage the voice-over volume more effectively.
