Resurrecting an old thread.
I just noticed that in https://bugs.maemo.org/show_bug.cgi?id=7190
,comment #47 there is a newer package to replace pulseaudio for 1.3.
same version of Pulseaudio with a new free list implementation.

If you still have occasional stutters playing audio and feel adventurous you may try it.
I installed it and I think it delivers.
