If you use your TV speakers for audio, then set your Apple TV audio format to stereo.

If you use a surround sound setup with optical cable, then set your Apple TV audio format to Dolby Digital 5.1.


Apple TV has three audio formats:

  • Automatic “Best quality”: PCM Multichannel, up to 7.1
  • Dolby Digital 5.1: compressed surround sound, downmixed from the source audio
  • Stereo: PCM uncompressed two channel audio, downmixed from the source audio


Use option (2) or (3) as applicable, when the first/default isn’t supported by your equipment.
