Key features
- Current route:
currentOutputs()returns the active audio outputs. - Override output:
overrideOutput()forces the speaker or returns to the default route. - Route changes: the
routeChangedevent fires when headphones or other devices connect or disconnect. - Interruptions: the
interruptionevent fires when a call or another app interrupts audio. - Platforms: iOS. iOS only. Android and web are stubs.
This plugin works on iOS only.
This plugin is a port of https://github.com/saghul/cordova-plugin-audioroute and allows iOS applications to get notified about audio session interruptions and route changes (for example when a headset is connected). To query and override the audio device in use is also supported.
Why Capacitor AudioSession?
The only free and maintained iOS audio session plugin for Capacitor:
- Audio route control - Detect and manage headphones, Bluetooth, speakers
- Interruption handling - Respond to phone calls, alarms, and other interruptions
- Output override - Force audio to speaker or restore default routing
- Same JavaScript API - Compatible interface with paid alternatives
- iOS-specific - Leverages AVAudioSession for deep iOS integration
Essential for VoIP apps, music players, podcast apps, and any app requiring precise audio routing control.

Install
You can use our AI-Assisted Setup to install the plugin. Add the Capgo skills to your AI tool using the following command:
npx skills add https://github.com/cap-go/capacitor-skills --skill capacitor-plugins
Then use the following prompt:
Use the `capacitor-plugins` skill from `cap-go/capacitor-skills` to install the `@capgo/capacitor-audio-session` plugin in my project.
If you prefer Manual Setup, install the plugin by running the following commands and follow the platform-specific instructions below:
npm install @capgo/capacitor-plugin-audiosession
npx cap sync
For now this plugin works only in Capacitor 4.0+.

iOS-only plugin to query and control the audio session output and listen to route changes and interruptions.
currentOutputs()
currentOutputs() => Promise<AudioSessionPorts[]>
Get the current active audio output routes.
On web and non-iOS platforms, this resolves to an empty array.
Returns: Promise<AudioSessionPorts[]>
overrideOutput(...)
overrideOutput(type: OutputOverrideType) => Promise<OverrideResult>
Override the current audio output route.
Use speaker to force playback through the built-in speaker, or
default to restore the system-selected route.
| Param | Type | Description |
|---|---|---|
type | OutputOverrideType | The desired output override type. |
Returns: Promise<OverrideResult>
addListener('routeChanged', ...)
addListener(eventName: 'routeChanged', listenerFunc: RouteChangeListener) => Promise<PluginListenerHandle>
Listen for audio route changes (e.g. headset connected/disconnected).
| Param | Type | Description |
|---|---|---|
eventName | 'routeChanged' | The route change event name. |
listenerFunc | RouteChangeListener | Callback invoked with the route change reason. |
Returns: Promise<PluginListenerHandle>
addListener('interruption', ...)
addListener(eventName: 'interruption', listenerFunc: InterruptionListener) => Promise<PluginListenerHandle>
Listen for audio session interruptions (e.g. incoming call) and their end.
| Param | Type | Description |
|---|---|---|
eventName | 'interruption' | The interruption event name. |
listenerFunc | InterruptionListener | Callback invoked with the interruption type. |
Returns: Promise<PluginListenerHandle>
getPluginVersion()
getPluginVersion() => Promise<{ version: string; }>
Get the native Capacitor plugin version
Returns: Promise<{ version: string; }>
