Strange "clicking" when importing file from video

We are currently working on a file that we imported from a video file. It plays back fine in the video editor (Adobe Premier Pro) but when played back in WL 9.5 on a Mac we are getting very soft clicks, which to me usually means a clocking problem. The file is 16bit 48 kHz. Any ideas or thoughts? Thanks! We wanted to do some clean up on the file which is why we imported it into WL.

When you zoom in, do you see broken waveforms? The spectrogram can help too.

Is the playback frame rate in Premier correct in the preview pane? ie 29.97 not 30 That can possibly result in clicks on resultant audio file export.

I will check. Thanks.
