Abstract

A system and method for improved audio controls on a personal computer is provided. The system and method provide a unified architecture for audio controls across hardware and software interfaces of the personal computer. An intelligent facility may automatically change audio controls for users to simply interact with various communications and media applications. To this end, a configurable audio controller intelligently handles various aspects of the system'"'"'s audio devices by following various rules that may be based at least in part on user-configurable settings and a current operating state. The present invention also provides audio controls so that a user may easily change audio settings such as the volume of an audio output device. There are many applications that may use the present invention for automatic control of audio devices based upon the user'"'"'s context.

16. A method for controlling audio devices in a computer system, comprising the steps of:

receiving an event corresponding to receiving an incoming telephone call;

communicating the event to a configurable audio controller;

determining a change in a setting of a plurality of audio devices from the event; and

changing the setting of a plurality of audio devices as a result of the determination, including lowering the volume of an audio output device before establishing the incoming telephone call on an active receiver.

17. The method of claim 16 wherein receiving the event comprises receiving an event generated by at least one of:

an application, a system component, and an audio control.

18. The method of claim 16 wherein the changing the setting of a plurality of audio devices comprises muting at least one other audio output device before establishing the incoming telephone call.

19. The method of claim 16 further comprising, restoring the audio output device setting to a prior state after the telephone call is disconnected.

20. The method of claim 16 further comprising, restoring the audio output device setting to a prior state after a headset is unplugged.

21. The method of claim 16 wherein determining the change in the setting comprises using rules for changing the setting of the audio device based upon one or more events.

22. The method of claim 16 wherein determining the change in the setting comprises using configuration settings.

23. The method of claim 16 wherein the changing the setting further comprises changing a setting of an input audio device.

24. The method of claim 16 further comprising changing an indicator that uses at least one member of a set comprising visual, audible, and tactile representations.

25. The method of claim 24 wherein the indicator corresponds to a visual indicator, and wherein changing the indicator comprises changing an amount of light displayed for a volume setting.

26. A computer storage computer-readable medium having computer-executable instructions for performing the method of claim 16.

27. A method for controlling audio devices in a computer system, comprising the steps of:

receiving an event corresponding to disconnecting a telephone call;

communicating the event to a configurable audio controller;

determining a change in a setting of a plurality of audio devices from the event; and

changing the setting of a plurality of audio devices as a result of the determination, including restoring an audio output device setting to a prior state after the telephone call is disconnected.
