Abstract: A method and apparatus for controlling a volume of a device is provided herein. During operation, a first device will receive a volume-adjustment message from a second device, along with an identity of an active application being run on the second device. The volume-adjustment message indicates whether or not the second device increased or decreased their volume. The first device will increase or decrease their volume in a similar manner as the second device if the first device is currently running a same active application as the second device; otherwise the first device will adjust its volume in an opposite direction as indicated in the volume-adjustment message.
