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

@return Internal type name which match this file ... or nothing if it is unknown.
