@Lorraine : Do you have the Firestick connected directly to the TV, or is connected to your Sky Q or Bose system? Have you tried connecting the Firestick to another HDMI input to see if the issue persists? Also, try heading into the Firestick settings > Display and Sounds > Audio > Dolby Digital Output, and disable Dolby Digital Plus if applicable to see if this helps. While you're here, check your other available audio settings to see if there's anything you can adjust that might resolve the issue.
