Audio with crackling sound using the JVC HM-DH30000U

[Litaiff]

A strange popping noise in the audio, like a crackling, occurs on some VHS tapes when I play them on my D-VHS JVC HM-DH30000U. It's not always the case, but it seems that some type of tape or recording on it causes this to happen to the audio. I'll give you an example.

Out of 10 tapes from the same person that arrive here and that I play on it, at least 1 or 2 end up like this. Any solution?

I hear a random high pitched ticking. This can be reduced with an audio Declick tool.

But the more difficult problem I hear is many momentary dropouts of the sound. This can be caused by a dirty tape at its top edge or a tape stretched at its top edge. I'm a transfer technician. I would inspect the tape under the cassette flap to see if the tape is stretched or otherwise damaged, especially at the top edge.
