DYNAMIC ROUTING OF AUDIO AMONG MULTIPLE AUDIO DEVICES

摘要

A routing screen is presented on an electronic device by a user interface application in response to receiving a notification that an external audio device is connected to the electronic device. The routing screen displays representations of an internal audio device and the external audio device. In one aspect, the representations are buttons. In another aspect, the representations are entries in a list. If a user selects one of representations, the user interface application causes the audio signals to be routed to the audio device represented by the selection. An application control screen having a set of objects that represent functions for an audio application may also be displayed. One of the objects on the application control screen is modified in response status changes in the external audio device. A user may select this object to access the routing screen when the external audio device is connected.
