i have found my answer.
as the playback freeze and stuttering etc appeared to me to be an interrupt issue of some sort i i have played hard with this.
by removing the following input packages
xserver-xorg-input-elographics
&
xserver-xorg-input-wacom
which also removes the meta-package
xserver-xorg-input-all
most of my sound issues are gone.
as i do not have those input devices this does not bother me
and the sound is superb
i hope this helps others.
