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

    @devstatus      ready
    @threadsafe     yes
