Updates: ubuntu lucid 10.04 half fix the issue for me, there were some
situation that the audio is a little bit behind around 3 seconds, contrast
to centos 5.x it's reproducible everytime, my venture on FC 14 has also
improve the situation.

the only permutation that i haven't test or tried is to backport some
reasonable recent kernel to Centos 5.x base. will explore this in a matter
of days.
