Abstract

There is provided a method of redirecting an audio stream from a first audio endpoint to a second audio endpoint in a computer operating system. The method includes directing the audio stream from a client application through a first audio resource stack to the first audio endpoint; creating an audio endpoint bridge to provide a path for the audio stream from the first audio resource stack through a second audio resource stack connected to the second audio endpoint; and redirecting the audio stream to the second audio endpoint using the audio endpoint bridge. The audio endpoint bridge can be created by forming a bridging application so as to activate the second audio stack. The bridging application can be hooked into a Windows audio engine in the second audio resource stack.

Claims

1. A method for redirecting an audio stream from a first audio endpoint to a second audio endpoint in a computer operating system, the method comprising:

directing said audio stream from a client application through a first audio resource stack to said first audio endpoint;

creating an audio endpoint bridge to provide a path for said audio stream from said first audio resource stack through a second audio resource stack connected to said second audio endpoint; and

redirecting said audio stream to said second audio endpoint using said audio endpoint bridge.

2. The method of claim 1 further comprising muting said first audio endpoint.

3. The method of claim 1 further comprising enabling said audio stream to be outputted by said first audio endpoint and said second audio endpoint.

4. The method of claim 1, wherein said audio endpoint bridge is created by forming a bridging application so as to activate said second audio stack.

5. The method of claim 4, wherein said bridging application is formed by an audio processing object in said first audio resource stack.

6. The method of claim 4, wherein said bridging application is hooked into a Windows audio engine in said second audio resource stack.

7. The method of claim 1, wherein said computer operating system is Windows Vista.

12. The system of claim 1, wherein said controller is further configured to utilize an audio processing object in said first audio resource stack to form said bridging application.

8. A system for redirecting an audio stream from a first audio endpoint to a second audio endpoint, the system comprising:

a controller configured to direct said audio stream from a client application through a first audio resource stack to said first audio endpoint;

said controller further configured to create an audio endpoint bridge to provide a path for said audio stream from said first audio resource stack through a second audio resource stack connected to said second audio endpoint; and

said controller further configured to redirect said audio stream to said second audio endpoint using said audio endpoint bridge

9. The system of claim 8, wherein said controller is further configured to mute said first audio endpoint.

10. The system of claim 8, wherein said controller is further configured to enable said audio stream to be outputted by said first audio endpoint and said second audio endpoint.

11. The system of claim 8, wherein said controller is further configured to create said audio endpoint bridge by forming a bridging application so as to activate said second audio stack.

13. The system of claim 11, wherein said bridging application is hooked into a Windows audio engine in said second audio resource stack.

14. The system of claim 8, wherein said computer operating system is Windows Vista.

15. A system for redirecting an audio stream from a first audio endpoint to a second audio endpoint in an operating system, the system comprising:

a first audio resource stack for directing said audio stream from a client application to said first audio endpoint, said first audio resource stack comprising an audio processing object;

a second audio resource stack connected to said second audio endpoint bridge;

an audio endpoint bridge for redirecting said audio stream from said audio processing object through said second audio resource stack to said second audio endpoint.

16. The system of claim 15, wherein said audio processing object is configured to mute said first audio endpoint.

17. The system of claim 15, wherein said audio processing object is configured to enable said audio stream to be outputted by said first audio endpoint and said second audio endpoint.

18. The system of claim 15, wherein said audio processing object is configured to form a bridging application so as to activate said second audio stack, thereby creating said audio endpoint bridge.

19. The system of claim 18, wherein said bridging application is hooked into a Windows audio engine in said second audio resource stack.

20. The system of claim 15, wherein said computer operating system is Windows Vista.
