VideoStudio :: Sound Echo After Creating Video File

Using X5 to create a video file from a project file in the timeline.

After the file completes rendering, the project preferences default is set to play the rendered file. But I find that when the playing commences after rendering, the sound has an echo effect that isn't part of the original files. Like the original sound is reflecting off walls, and you get the same sound just spaced apart by a small time period. I've tracked this to what appears to be X5 playing both the rendered file and the project file at the same time. If I turn the project preferences item "play after render" off, off course nothing happens after rendering completes. And separately playing the rendered file, the sound is normal.

Is there a way to stop this echo effect? Ideally, just play the rendered file only. But failing that, change the preferences default. However, there does not seem to be any way to change the project preferences default for this item.
