Let's brainstorm..Setting up MinimServer to feed a USB DAC

The lack of volume control doesn't concern me because I will be connecting it to powered monitors and I can use the volume controls on the monitors. At some stage I am hoping to add a pre-amp as this would be more convenient for small volume adjustments and would allow me to use multiple inputs.

I've got the Stoner DAC now (there's a story to be told about why it took so long) and I tried to use it as a plug-in replacement for the built-in audio output. The result is that the track appears to play in Kinsky (the time is advancing), but there's no audio.

Here's a section of the log that was produced about the time I started to play the track:

Does this provide any clues to what's wrong?
