PD16: Problem is songs added to complement video segments randomly become contaminated with this terrible echoing. Completely corrupts the music track. Sometimes I can work for hours on a video without the issue. Sometimes it appears minutes into a creation.

• The contamination appears to coincide with a video segment that has an effect applied to it. No effect in particular. Could be any change from the original video. Titles will trigger it as well.

It can occur with video segments that contain their own audio track, having the video audio muted for that track, or video segments with no audio track.

It can occur with a single track video, or multitrack layered video.

When it occurs, the anomaly only impacts the single song on the music track. Other songs on the same track are not affected. Nor are overlapping music tracks affected. And not all of the track is affected. Usually commences where the cursor meets a violating video segment, but then contaminates the remainder of the song.

This condition occurs whether the music is added to PD16's dedicated music track or any audio track.

It transcends to any PRODUCED video as well.

It does not seem to matter what else is running on the computer. Only having PD16 open can experience the same issue.

To resolve the issue sometimes simply re-saving the project fixes it. Most often the affected song needs to be replaced, or the song has to be replaced and PD16 relaunched. Other times replacing the suspicious video segment does the trick. Even with that there are no guarantees the issue won't resurface.

Computer config is:
Win 10
PD16 V 3424.0
Dell XPS 8930
32G RAM
NVIDIA GeForce GT1070
