Q: Apple TV, Sound setting w/ Soundtouch 130
Should Apple TV users being using AUTO, or Dolby Digital 5.1 for the sound setting on Apple TV Gen4?
- Auto – In most cases, Auto is the best setting. It allows the Apple TV to automatically detect the capabilities of the device you are connected to and deliver the appropriate audio stream. If you are connected to a stereo device it will send stereo PCM audio; but if you are connected to a multichannel device, it will send multichannel PCM audio, including 5.1 or 7.1, depending on the capabilities of the connected HDMI device.
- Dolby Surround – This setting is intended to 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.
