bitstreams.

Option Description
Speaker Configuration
Select an option from the drop-down list. The setting defines the

setting is reflected in channel descriptions of the audio level meters.
Speakers that receive no content from the input source are silent.

Provides a choice between Auto, LtRt, or LoRo downmix modes.
Dolby Atmos Decode (for
Dolby Digital Plus
bitstreams only)
Enable Dolby Atmos content decoding with the Dolby Atmos

channel-based content and does not apply to audio objects.
