By default, Apple TV uses the best audio format available. If surround sound isn't working, try changing the audio format to Dolby Digital 5.1. To do this, on your Apple TV go to Settings > Video and Audio > Audio Format and turn on Change Format. Here you can choose Dolby Digital 5.1 (instead of Use Best Available).

If changing the audio format to Dolby Digital 5.1 doesn't help, try changing the Audio Format to Stereo. For more info about audio settings, go to Apple's Play audio in Dolby Atmos or surround sound article.
