i like the solenoid as a source of buzzing. Could also be a loose vacuum hose. Most become pressure hoses under boost and can buzz or whistle at certain pressures if the are split or have a loose connection. I spent days hunting for a buzz that was coming from the hose leading to the one way check valve before the pcv connection on the valve cover. this hose runs through a larger foam insulating hose and hid the split.
