Quoted from Cmjb13:
When I start a new game, I hear multiple clicking sounds that sound like a ball is stuck
I’m hearing those same sounds at random times during gameplay while on the same ball.
You can hear it in the first and last 5 seconds. More annoying than anything else
Unfortunately the video is not very helpful, but if I had to guess, i'd say its maybe your drop target reset coil(s) are firing due to dirty optos, or maybe your right sling is activating due to vibration because the gap in one or more of the the leaf switches is too small... Pop bumpers can also have this problem. You need to identify what coils are firing, to determine how to resolve this issue.
