Then you can try to change Audio Renderers merits in Graphstudio, giving your preferred sound device the highest merit.

Thanks again but Graphstudio does not allow merits to be changed for audio renderers as far as I can see. Although it does list merits for renderers in the list of filters, the field is missing in their individual property pages and the button to change merit is inoperable for them.

Can you or anyone confirm this problem on their own system? If this is in fact a bug there's no point in me continuing to try to find a solution.
