Abstract

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.

Claims

1. A computer-readable medium containing executable program instructions that cause a data processing system to perform a method comprising:

presenting a routing screen on an electronic device in response to receiving a notification that an external audio device is connected to the electronic device, the routing screen displaying representations of an internal audio device and the external audio device.

2. The computer-readable medium of claim 1 wherein the method further comprises:

receiving a selection of one of the representations on the routing screen; and

causing audio signals from the audio application to be routed to the audio device represented by the selection.

3. The computer-readable medium of claim 1, wherein the method further comprises:

presenting an application control screen on the electronic device as a set of objects that represent functions for an audio application executing on the electronic device.

4. The computer-readable medium of claim 3, wherein the method further comprises:

modifying one of the objects on the application control screen in response to connecting the external audio device; and

replacing the routing screen with the application control screen having the modified object.

5. The computer-readable medium of claim 4, wherein the method further comprises:

replacing the application control screen having the modified object with the routing screen in response to receiving a selection of the modified object.

6. The computer-readable medium of claim 4, wherein the method further comprises:

modifying the one of the objects on the application control screen in response to disconnecting all external audio devices.

7. The computer-readable medium of claim 3, wherein the method further comprises:

presenting the application control screen on the electronic device in response to an audio device initiating an audio application.

8. The computer-readable medium of claim 3, wherein the objects comprise buttons.

9. The computer-readable medium of claim 1, wherein the representations comprise buttons.

10. The computer-readable medium of claim 1, wherein the representations comprise entries in a list of connected devices if the connected devices exceed a maximum number of buttons on the routing screen.

11. The computer-readable medium of claim 1, wherein the method further comprises:

presenting the routing screen in response to initiation of an audio application if any external audio devices are connected to the electronic device.

12. The computer-readable medium of claim 1, wherein the electronic device comprises a communications device.

13. A computer implemented method comprising:

presenting a routing screen on an electronic device in response to receiving a notification that an external audio device is connected to the electronic device, the routing screen displaying representations of an internal audio device and the external audio device.

14. The computer implemented method of claim 13 further comprising:

receiving a selection of one of the representations on the routing screen; and

causing audio signals from the audio application to be routed to the audio device represented by the selection.

15. The computer implemented method of claim 13 further comprising:

presenting an application control screen on the electronic device as a set of objects that represent functions for an audio application executing on the electronic device.

16. The computer implemented method of claim 15 further comprising:

modifying one of the objects on the application control screen in response to connecting the external audio device; and

replacing the routing screen with the application control screen having the modified object.

17. The computer implemented method of claim 16 further comprising:

replacing the application control screen having the modified object with the routing screen in response to receiving a selection of the modified object.

18. The computer implemented method of claim 16 further comprising:

modifying the one of the objects on the application control screen in response to disconnecting all external audio devices.

19. The computer implemented method of claim 15 further comprising:

presenting the application control screen on the electronic device in response to an audio device initiating an audio application.

20. The computer implemented method of claim 15, wherein the objects comprise buttons.

21. The computer implemented method of claim 13, wherein the representations comprise buttons.

22. The computer implemented method of claim 13, wherein the representations comprise entries in a list of connected devices if the connected devices exceed a maximum number of buttons on the routing screen.

23. The computer implemented method of claim 13 further comprising:

presenting the routing screen in response to initiation of an audio application if any external audio devices are connected to the electronic device.

24. The computer implemented method of claim 13, wherein the electronic device comprises a communications device.

25. A system comprising:

means for routing audio signals between an electronic device and a plurality of audio devices; and

means for interfacing to the electronic device, wherein the means for interfacing presents a routing screen in response to receiving a notification from the means for routing that an external audio device is connected to the electronic device, the routing screen displaying representations of an internal audio device and the external audio device.

26. The system of claim 25, wherein the means for interfacing further receives a selection of one of the representations on the routing screen and sends a notification to the means for routing to cause audio signals from the audio application to be routed to the audio device represented by the selection.

27. The system of claim 25, wherein the means for interfacing further presents an application control screen on the electronic device as a set of objects that represent functions for an audio application executing on the electronic device.

28. The system of claim 27, wherein the means for interfacing further modifies one of the objects on the application control screen in response receiving a notification from the routing that the external audio device is connected and replaces the routing screen with the application control screen having the modified object.

29. The system of claim 28, wherein the means for interfacing further replaces the application control screen having the modified object with the routing screen in response to receiving a selection of the modified object.

30. The system of claim 28, wherein the means for interfacing further modifies the one of the objects on the application control screen in response receiving a notification from the means for routing that a last external audio device is disconnected.

31. The system of claim 27, wherein the means for interfacing further presents the application control screen in response to an audio device initiating an audio application.

32. The system of claim 25, wherein the means for interfacing further presents the routing screen in response to initiation of an audio application if any external audio devices are connected to the electronic device.

33. The system of claim 25 further comprising:
