388     @descr      We try to detect, if given file could be handled by this class and is a well known one.
389                 If it is - we return right internal type name - otherwise we return nothing!
390                 So call can search for another detect service and ask him too.
391 
392     @attention  a) We don't need any mutex here ... because we don't use any member!
393                 b) Don't use internal player instance "m_pPlayer" to detect given sound file!
394                    It's not necessary to do that ... and we can use temp. variable to do the same.
395                    This way is easy - we don't must synchronize it with currently played sounds!
396                    Another reason to do so ... We are a listener on our internal ma_Player object.
397                    If you would call "IsSoundFile()" on this instance, he would call us back and
398                    we make some unnecessary things ...
