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.
