Force your audio output to switch to headphones, speakers, or any other output, including USB and Bluetooth devices.

The microphone can also be switched, and on most devices the speaker can be completely muted if you so desire.

Additional features:
Auto-Switch: Detect when headphones are inserted or removed, and switch to any audio output or mute/unmute the speaker automatically.
Restore-on-Boot: Automatically switch to the output of your choice when your device starts.
Widgets: Control the app from your home screen.

Common use cases:
This app can help if your device does not detect your headphones, or it thinks they are connected even when they have been removed.
It can also be used to mute the speaker when using headphones, so that loud notifications do not play via the speaker.
Want to use a headset microphone but still output audio via the speakers? also possible.
You can force audio to play locally on your device when using Android's native cast-screen feature.

Advanced users can trigger a switch externally using the following intent actions:
com.nordskog.LesserAudioSwitch.HEADPHONES
com.nordskog.LesserAudioSwitch.SPEAKER
com.nordskog.LesserAudioSwitch.BLUETOOTH
com.nordskog.LesserAudioSwitch.USB
