Option 1:
Increase the volume until the picture falls off the wall. The cracked glass and frame warpage will likely change the resonant frequency of the picture frame and should solve your buzzing problem.
Option 2:
Change your perception of the issue. Embrace the buzzing! Install hydraulic lift kit on house foundations, add chromed chain steering wheel, dingle balls and fuzzy carpet to taste. Attach license plate to rear of listening room with only one loose screw. Play only rap CDs with exaggerated bass, regardless of musical content.
