PARAMETER_DIGITAL_OUTPUT_MODE

static val PARAMETER_DIGITAL_OUTPUT_MODE: String

Sets the digital audio output mode.

This parameter controls the audio format sent to a digital output like HDMI or S/PDIF. This allows the user to select a specific audio format or let the system decide automatically. The supported values are:

• "Auto": The system automatically selects the preferred format supported by the connected device. (Default)
• "Bypass": The encoded audio stream is sent directly to the output without being decoded by this device.

Type: STRING

Value: "digital_output_mode"

PARAMETER_DOLBY_AUDIO_PROCESSING_DOLBY_ATMOS

static val PARAMETER_DOLBY_AUDIO_PROCESSING_DOLBY_ATMOS: String

Enables or disables Dolby Atmos processing.

Dolby Atmos creates a more immersive and realistic sound experience by adding a height dimension to surround sound. It allows sound to be placed and moved precisely around you, including overhead.

When set to true, Dolby Atmos processing is enabled. When set to false, it is disabled, and the audio will be processed using other standard settings. Disabling this parameter does not change the list of available audio formats presented to the audio framework.

Note: This setting is only effective on devices that support Dolby Atmos; on unsupported systems, this option may be ignored or hidden. To experience Dolby Atmos, you need content specifically mixed for it. The immersive effect can be delivered through a dedicated Dolby Atmos sound system or through virtualization technologies for headphones and built-in speakers.

Type: BOOLEAN

Value: "dolby_audio_processing_dolby_atmos"

PARAMETER_DOLBY_AUDIO_PROCESSING_SOUND_MODE

static val PARAMETER_DOLBY_AUDIO_PROCESSING_SOUND_MODE: String

Sets the sound mode for Dolby audio processing.

This parameter allows the selection of a preset audio profile to optimize the listening experience for different types of content. The supported values are:

• "Game"
• "Movie"
• "Music"
• "News"
• "Stadium"
• "Standard"
• "User"

The default value is "Standard".

Type: STRING

Value: "dolby_audio_processing_sound_mode"

PARAMETER_DOLBY_AUDIO_PROCESSING_SURROUND_VIRTUALIZER

static val PARAMETER_DOLBY_AUDIO_PROCESSING_SURROUND_VIRTUALIZER: String

Enable/disable the Surround Virtualizer.

The Surround Virtualizer creates a virtual surround sound experience when playing back Atmos, surround, and stereo content over two-channel endpoints like TV built-in speakers and headphones. It expands the soundstage and adds depth to the audio, creating an immersive effect without a multi-speaker setup. Note: When Dolby Atoms playback streams are active, this will always be true.

Type: BOOLEAN

Value: "dolby_audio_processing_surround_virtualizer"

PARAMETER_DOLBY_AUDIO_PROCESSING_VOLUME_LEVELER

static val PARAMETER_DOLBY_AUDIO_PROCESSING_VOLUME_LEVELER: String

Enable/disable Volume Leveler.

Volume Leveler helps to maintain a consistent volume level across different types of content and even within the same program. It minimizes the jarring jumps between loud commercials or action sequences and quiet dialogue.

Type: BOOLEAN

Value: "dolby_audio_processing_volume_leveler"

PARAMETER_DOWN_MIX_MODE

static val PARAMETER_DOWN_MIX_MODE: String

Sets the downmix mode for multi-channel audio.

This parameter determines how multi-channel audio (e.g., 5.1) is converted to a two-channel stereo output. This is useful when the playback device, like headphones or TV speakers, has fewer channels than the source audio.

The supported string values are:

• "Stereo": A standard downmix (Lo/Ro) suitable for most stereo playback devices. (Default)
• "Surround": A downmix that is matrix-encoded with surround sound information (Lt/Rt).

Type: STRING

Value: "down_mix_mode"
