Music Control Overview

Music Control sends playback and playback-volume commands through a connected AIBuds device.

Available Features

📄️Control Music Playback

Control playback, track navigation, muting, and playback volume

Getting Started

1. Connect to the Device - Wait until the device is connected and ready.
2. Check Protocol Conformance - Verify support for DeviceMusicControlAPI.
3. Choose a Command - Play, pause, select the next or previous track, or adjust playback volume.
4. Handle Completion - Update application UI only after the command reports success.

Key Concepts

Playback Commands

• playMusic starts or resumes playback.
• pauseMusic pauses playback.
• playNextMusic and playPreviousMusic navigate the playback queue.
• The public protocol does not define a stop command.

Playback Volume Commands

• musicVolumeUp and musicVolumeDown move by one device-defined step.
• mute and unmute control playback muting.
• setMusicVolume accepts an explicit level from 0 through 100.

Protocol Reference

Music Control is accessed through DeviceMusicControlAPI:

Swift

Swift

guard let device = device as? DeviceMusicControlAPI else {
    print("Device does not support DeviceMusicControlAPI")
    return
}

Objective-C

Objective-C

id<AIBudsDeviceMusicControlAPI> device = (id<AIBudsDeviceMusicControlAPI>)self.device;
if (![device conformsToProtocol:@protocol(AIBudsDeviceMusicControlAPI)]) {
    NSLog(@"Device does not support AIBudsDeviceMusicControlAPI");
    return;
}

Best Practices

1. Check Protocol Conformance: The SDK exposes no separate Boolean support query.
2. Handle Every Completion: Check success and report error when a command fails.
3. Debounce Sliders: Avoid sending every intermediate explicit volume value.
4. Observe Playback Changes: Use didMediaPlayStatusChanged when the UI must follow device notifications.

Notes

• The SDK does not expose the active player, track metadata, or playback queue through this protocol.
• Command success confirms command execution, not a permanent playback state.
• Volume Control and Music Control are separate protocols even though both include volume-related operations.
