Audio controller

Described herein is a multi-host computing system (100) having multiple host processors running different operating systems. In one implementation, a method of playing audio streams received from a plurality of hosts of a multi-host computing system (100), the method comprising receiving a second audio stream from a second host, and changing audio stream parameters associated with the second audio stream from second host to match the corresponding parameter values associated with a first audio stream received from a first host to generate an updated second audio stream. The method further comprises mixing the updated second audio stream with the first audio stream to generate a combined audio stream, and playing the combined audio stream using at least one audio codec (104) of the multi-host computing system (100).
