Device Changes

Device changes include changes in audio/video input and audio output devices. Plugging a headset, or disconnecting your airpods mid call are some of the example of device changes. These are all taken care of by the SDK without requiring any code.

Manual Device Change

You may still want to allow users to see the currently selected devices and change them if required. We'll do this in three steps -

1. Fetching all attached devices list from hmsStore.
2. Fetching the currently selected devices from hmsStore.
3. Calling hmsActions to change the device if required.

 
// {audioInput, audioOutput, videoInput}
const devices = hmsStore.getState(selectDevices);

// {audioInputDeviceId, audioOutputDeviceId, videoInputDeviceId}
const selected = hmsStore.getState(selectLocalMediaSettings);

const deviceId = 'default';
// show user a settings component to manually choose device

// call the corresponding method to change the device id
hmsActions.setAudioSettings({deviceId});
hmsActions.setVideoSettings({deviceId});
hmsActions.setAudioOutputDevice(deviceId);
