API Summary
This service controls the audio policy of a webOS system. Its role is to implement audio routing (sending audio streams to the proper destinations) and setting volumes in different scenarios.
Its functionality is categorized into the following modules:
- Master - To control the master volume of audio output devices.
- UMI - Handles connections and manages volume for audio resources, when playing audio from applications like YouTube.
- System - To control audio policy for DTMF (touch tones), alarm, calendar, and effects.
- Media - To control audio policy for media playback.
- Ringtone - To control audio policy for ringtone.
- Alert - To control audio policy for for alerts.
In addition, there is a 'soundSettings' category, to manage sound settings such as setting the output device for the audio.
Note: [Applicable for "Master", "UMI", and "SoundSettings"] The ‘audio’ service calls the ‘audiooutput’ service to communicate with the audio hardware layer.

Parameters
None
Call Returns
Name | Required | Type | Description |
|---|---|---|---|
| Return | Required | Object: CallReturn | Details of the method success/failure. CallReturn object contains returnValue, errorCode, errorText and Id. |
Example
luna-send -n 1 luna://com.webos.service.audio/ringtone/lockVolumeKeys '{}'
{"returnValue":true}
ringtone/offsetVolume
Description
Increment or decrease the volume of the current or specified scenario, in steps or percent. To increment the volume, pass a positive value. To decrease the value, pass a negative value.
Remark
Volume
- Range: [0-100]
- Unit: Percent
In case the unit is percent
New volume = Current volume + (step offset value(%) of maximum_volume_level)
e.g. If current volume = 10, step off set value = 50, maximu_volume_level =100
New volume = 10 + (50% of 100) = 60
In case the unit is step
New volume = Current volume + (step offset value * 11)
e.g. If current volume = 10, step offset value = 6,
New volume = 10 + (6 * 11) = 76
In both cases
- If the calculated value of the volume is higher than the maximum volume level (i.e. 100), the volume is adjusted to the maximum volume level.
e.g. If current volume = 70, offset = 50, unit = percent. Then new volume = 100. - If the calculated value of the volume is a negative value, the volume is adjusted to 0.
e.g. If current volume = 30, offset = -50, unit = percent. Then new volume = 0.
Parameters
Name | Required | Type | Description |
|---|---|---|---|
| offset | Required | Number | Offset value to be set to increase or decrease the volume.
|
| scenario | Optional | String | The scenario to apply the volume change to. If not specified, the current scenario gets the volume change. |
| unit | Optional | String | This is used to interpret the offset argument. The value will be one of the followings:
The default value of unit is step. |

system/offsetVolume
Description
Increase or decrease the volume of the current or specified scenario, in steps or percent. To increment the volume, pass a positive value. To decrease the value, pass a negative value.
Remark
Volume
- Range: [0-100]
- Unit: Percent
In case the unit is percent
New volume = Current volume + (step offset value(%) of maximum_volume_level)
e.g. If current volume = 10, step off set value = 50, maximu_volume_level =100
New volume = 10 + (50% of 100) = 60
In case the unit is step
New volume = Current volume + (step offset value * 11)
e.g. If current volume = 10, step offset value = 6,
New volume = 10 + (6 * 11) = 76
In both cases
- If the calculated value of the volume is higher than the maximum volume level (i.e. 100), the volume is adjusted to the maximum volume level.
e.g. If current volume = 70, offset = 50, unit = percent. Then new volume = 100. - If the calculated value of the volume is a negative value, the volume is adjusted to 0.
e.g. If current volume = 30, offset = -50, unit = percent. Then new volume = 0.
Parameters
Name | Required | Type | Description |
|---|---|---|---|
| offset | Required | Number | Offset value to be set to increase or decrease the volume.
|
| scenario | Optional | String | The scenario to apply the volume change to. If not specified, the current scenario gets the volume change. |
| unit | Optional | String | This is used to interpret the offset argument. The value will be one of the followings:
The default value of unit is "step". |
Call Returns
Name | Required | Type | Description |
|---|---|---|---|
| returnValue | Optional | Boolean |

| errorCode | Optional | Number | errorCode contains the error code if the method fails. The method will return errorCode only if it fails. |
| errorText | Optional | String | errorText contains the error text if the method fails. The method will return errorText only if it fails. |
