52 : @short handler to detect and play sounds ("wav" and "au" only!)
53 : @descr Register this implementation as a content handler to detect and/or play wav- and au-sounds.
54 : It doesn't depend from the target platform. But one instance of this class
55 : can play one sound at the same time only. Means every new dispatch request will stop the
56 : might still running one. So we support one operation/one URL/one listener at the same time
57 : only.
