Is bypassing KMixer worth the trouble?

I am just doing it...This is pretty complicated.

This is the link i found useful.I am not sure,but i think if it is done right,then the volume control (in Winamp or Foobar 2000) does not work anymore.I've just done it,and mine still works.I suck at this :(

I am not sure about sound quality,i am doing this just to try on my PC home.In my office i have really good system,i will know there.

And here is the link if you want Foobar to upsample with Secret Rabbit Code..

I wish someone with better knowledge could get into this thread.I could really use help.
I am on XP,not Vista,so i am not sure if this is of any use to you.

Sheldonn,is Foobar 2000+WASAPI output functional in Vista or in XP?Also,what version Foobar are you talking about,0.8 or 0.9?
I use XP and i have had some trouble with all this recently..
