Try different type dimmer or another one,
some times triac can go bad and it will fire
only half of cycle or at 180 degree instead of 360
when that happens it can get very noisy specially
at minimal load, 100W at triac that can pas 3 amp.
is minimal, I would change dimmer.

I have a 100W globe style bulb attached to a simple 2-way dimmer. The
thing (the bulb) buzzes like crazy on anything other than full on and full
off. You can even see the filament flapping in the inert breeze.

Is there no way to fully remove this buzzing? I know a little about the
higher speed switching techniques involved, and I also know about the wave
deforming that some do. But is there not something foolproof? Seems like
something that should have been solved by now.

Thanks
