It might be that the long hose is causing to much resistance to the air flow due to the turbulence induced by the hose. If so, the whistling might be any possible opening in the spackle bucket flange seal drawing air. Each foot of hose causes air turbulence, and therefore resistance to flow of the air. Collapsible or ridged hose increases the turbulence versus a smooth wall hose. Your vacuum incoming CFM might be just overwhelming the delivery capacity of the bucket with the long hose attached. The resistance goes away when you remove the hose, and so does the whistle! You might need a slight bypass valve (hole) to allow more air to enter the bucket to augment the incoming air through the hose, just need to find the sweet spot where it doesn’t reduce the suction.
