40 * Class Name: CAudioPolicy
42 * Description: This class is ultimately implemented by the product team based
43 * on their requirements for audio behavior in the face of
44 * multiple audio requests simultaneously. The reference
45 * implementation is a simple priority scheme. If a request is
46 * a higher priority, it gets played, even if termination of a
47 * running request of lower prioirity is required.
