Media room problem

Overview - Video Sources:
-WDTV hooked up to TV.
-PS3 hooked up to Projector.
-Laptop (Standalone)

Overview - Audio Sources:
-Wireless headphones
-Full-room speakers
-Half room 1 speakers
-Half room 2 speakers

Note: All of the audio sources are outputted in standard audio jacks

The Question:
Is there any type of switcher box/manual switch so that I can switch all 4 audio sources between my 3 video sources?

Sorry for being such a multi-tasking whore :frowning:
