I'm a little confused by this. With my Libranet system I can use the Kmixer to get all 4 of my pc speakers to have output. With the Mandrake 9.2 setup I only have 2 speaker output (from the rear speakers) and the Aumix doesn't give me any options for adjusting this. I'd like to give Aumix a try before installing Kmix, so maybe someone can help me figure out why this works the way it does... especially the rear speaker/front speaker reversal.
