Maps InputChannel events to handlers.
interface InputChannelEventMap {
"input-device-changed": (event: AudioDeviceChangedEvent) => void;
"input-device-lost": (event: AudioDeviceLostEvent) => void;
}
Used by InputChannel.addEventListener().
input-device-changed: (event: AudioDeviceChangedEvent) => void - Fired when a device was opened with setInputDevice(), or a stream was connected with setMediaStream() (current is then null). See AudioDeviceChangedEvent.input-device-lost: (event: AudioDeviceLostEvent) => void - Fired when the device was unplugged, permission was revoked, or an external stream ended. For a local device with fallbackToDefault enabled, the default input device is opened afterwards. See AudioDeviceLostEvent.
