My 45 year old Rubio lute had more than buzzing; it was rattling. The braces had come loose when I took it to New York to the shop of Tom Hom for adjusting the action. He kept it in his NYC shop that had no humidifiers for 6 months. It also split the top. I could make it rattle by tapping with the back of my knuckles. The solution was to have Mel Wong remove the top and reglue the braces. This is major surgery! Fortunately, Mel had sufficient skill to pull it off. Delaminating braces in guitars is common enough that there are many videos on youtube on how to fix them, but guitars yield access to the braces through the sound hole (except for Antonio Torres second era guitars with a tournavaz) and lutes do not.

I'm not sure if it is a loose bar or some weird resonance. The buzzing only happens on certain courses and I can't isolate where it's coming from. Has anyone some advice for me? Thanks!
