I am very casual sound user so I unfortunately cannot tell when exactly the problem appeared first; but I am pretty sure that in 2.6.14 I could normally watch video or listen CD without much strain. I appreciate any pointers how to debug it further; if required I am ready to try to recompile older kernel (as time permits).
