Said and done .. therefore ordered the X-FI Surround 5.1 Pro USB. But what I realized? There is no setting for the "Bass redirect" / "Bass Redirection" .. thus denied the same also at my Concept E Magnum Power Edition perfectly the service .. too bad .. will probably go back again .. regarding the lousy driver Policy / Updates I am Creative really disappointed ..
Update: Please see the comment. I have not tested it myself, but it seems well to be a way to solve the problem I have described.
