Well, I guess my whole perception of how 5.1 is supposed to work with this sound device and my analog speakers was wrong. I am now lead to believe, please correct me if I am wrong, that the only way to get surround (not true 5.1) is to use the software's "surround" option, which actually just bleeds the front channels to the rears with a fraction of delay. The only way to get true 5.1 discrete channels is through the digital out and to digital speakers using a source that is truly 5.1 encoded. Is that right? That would explain a lot. Anyway, with the help I have gotten here I have everything sounding pretty good. I use the EQ in Windows Media Player but understand that there are several better free ones. I will look into that.
Thanks for everything
