  I tried the stuff in the directory http://people.freebsd.org/~ariff/lowlatency
  And it works! GREAT! :)
  At least stereo output is working, I will do more tests later.
  At this point I can say, audio is working with FreeBSD 6.2 Release on a VIA EPIA EX10000.
  Thank you very much!
   
  Here some output of my box:
