ABSTRACT:
The computer system includes a stereo audio circuit a universal serial bus (USB) controller, or other isochronous device controller. Left front and right front stereo audio channels are routed through the audio circuit to a pair of stereo speakers. One or more surround sound channels, perhaps including left rear and right rear channels, are routed through the USB controller to one or more USB peripheral surround sound speakers. The audio circuit and the USB controller operate from separate asynchronous clocks. A variety of techniques are disclosed for maintaining synchronization of the audio signals routed through the audio circuit and through the USB controller despite possible clock skew between the asynchronous clocks. Method and apparatus embodiments of the invention are disclosed.
