Audio resources are shared between two zones to enable one zone to route audio to the other zones. However, due to possible network delays, the pro- gramming of an audio resource may reach one zone faster than the other zone. This may result in one zone (say Zone 1) to be able to use the audio resource, and the other zone (say Zone 2) either not be able to use the resource completely or be able to use the resource partially. However, as Zone 1 is not aware The zones calculate a local capability of an audio resource. The local capability is the ability of the local zone to be able to use a resource looking at only resources available at the local zone. This capa- bility is exchanged between the two zones. The total capability of the shared audio resource is determined using both the local capability, the remote capabil- ity (local capability of the resource as calculated by the remote zone) among other resources. With such an approach, as soon as Zone 2 realizes that the local capability of the audio resource has changed, it will send this information to Zone 1, which will then downgrade the resource appropriately.
