Ah, I thank you so very much. I was completely lost and it’s hard to search for this kind of problem in google or even here directly.
I couldn’t change the rear speakers directly or so but I changed from Microsoft Soundmapper to Microsoft Surround-Mapper and that of course just did the trick.
You guys are helping me out for the third time now I think. Here is the place where a professional helps you. Thank you very much again and have a nice start into the new year. =)
