You get the HDMI sources to either detect the coding required or turn OFF the "Passthrough" option.

Apple TV 4

Apple TV > Settings > Video and Audio > Audio Format > AUTO

Decode Mode Off - No up-mixing performed Auto - PCM streams up-mixed using DTS Neo 6 Auto algorithm DTS Neo 6 Music - PCM streams up-mixed using DTS Neo 6 Music algorithm DTS Neo 6 Video - PCM streams up-mixed using DTS Neo 6 Movie algorithm The Decode Mode setting is applicable to audio received by the following sources: HDMI, HDMI ARC, HDMI eARC, SPDIF and Toslink Streaming sources (radio, Qobuz, etc.) and analogue inputs cannot be up-mixed. These will always be presented in stereo. For all modes above downmixing if required will then be performed based on the number of speakers in the system.
Dynamic range compression Standard This mode has the widest dynamic range (the difference between the quietest and loudest sounds). Quiet remains quiet, loud remains LOUD (i.e. explosions will "blow your socks off!") Medium This mode has a medium difference dynamic range. Making quiet sounds louder and louder sounds quieter (not as big a difference in sound volume) Maximum This is maximum compression Making quiet sounds louder and louder sounds quieter (not as big a difference in sound volume and "keeps your socks on")
