[Roman_V_M]

Thanks for the reply Roman, but a quick test shows that this is not the case for me. The logs indicate that the dsplayer setting seems to do nothing when a renderer is chosen for playback - it generates a list of all the renderers, the default is always at the top, and it never fails to pick it, directsound or not.

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