Sound problem

[homeboy26]

I have two licences and have just re-installed Notation 3.04 on both my desktop and laptop.
When I play my saved notation score on either it plays back with a warbly music sound which is impossible to recognise as what I composed. Like its not being "driven" correctly. Wishy washy sounding. Lacking clarity or note sound definition.


From sometime way back I seem to recall this able to be remedied by changing a setting in the Registry?
If someone knows what I need to do to get back my "proper" sound when playing scores, Please let me know.
I am stuck with this warbly sound and cannot play scores so as to properly listen to them, or even begin to create new or modify earlier saved scores as the sound is really annoyingly terrible to have to contend with.
Cheers
