This scenario will play an audio stream tagged with the Communications category. This category is used by VOIP apps, such as Skype and Lync. If a separate communications device is connected (Blutooth HFP) audio will play via that endpoint instead of stereo
speakers. Note the interactions between Media/Movie audio and Communications streams. Play one using the Audio Category SDK sample, and then the other with Audio Category Copy SDK sample to see how they interact. Communications
will attenuate the Music and Movie streams (so that users use VOIP apps to chat while there is audio in the background).
To observe how each stream category interacts with the others, run both the Audio Category Sample and the Audio Category Companion sample side by side.
