That is actually what I am using now. Many of the members of Hercules' own forum have said that the 4 speaker issue works in the 1.xx drivers and are still using them.
I can get it working, but if I change the song I lose the rear channel. I can get them back by stopping and changing to 2 speaker and back, but that gets annoying. I would rather just leave it be. I use winamp for mp3's by the way. I don't really need them to be accellerated.
Otherwise I love the card and will never go back to creative.
EDIT: doh! I just read I should leave it on 4 channel unless I am watching a dvd. It is working better now. Kicka$$!!
