How to setup Dolby Digital 5.1 Surround Sound on Apple TV 4/3?
In the Apple TV settings, go to the Audio and Video settings, and then into the Surround Sound section. There you will see options for Auto, Dolby Surround and Stereo.
Here, you should chose the “Dolby Sound” option, which will force the Apple TV to output a Dolby Digital (also known as “AC3”) compressed bitstream. This may be required with certain legacy devices or sound bars that support the older Dolby Digital format but do not yet support Dolby Digital Plus or multichannel PCM audio. Remember that Dolby Digital is only capable of up to 5.1 channels of audio, so this option will never be able to send 7.1 channel audio to the connected HDMI device.
When this setting is selected, the audio is first decoded (although constrained to 5.1 channels) and mixed with other system sounds, and is then reencoded to the legacy Dolby Digital format just prior to the HDMI output. The connected device (TV, sound bar or AVR) will then receive a Dolby Digital bitstream.
