HBO GO is updating their app on the new Fire TV to bring new features, exclusive Sesame Street content, and parental controls to customers. To enable these updates, HBO has made the decision to disable Dolby on HBO GO for a short period of time and we are informing you now as a courtesy. HBO plans to release an update to re-enable Dolby in March.
If you would like to receive an email when Dolby 5.1 surround sound will be supported again, please email HBO at HBOGONotifications@hbo.com or you may contact HBO Customer Support for more information.
