Can you advise if the FB3 is connected to a laser projector or is it just by itself?

i had the same when i checked my projectors today, turned out to be a grounding problem inside one of the projectors.
Open up your projector and see if the ground has a good connection to the laser box.
Mine is solved now

Yes, for sure this has nothing to do with our software or hardware.
When using sound with the computer, you should be using something called a "DI box". http://en.wikipedia.org/wiki/DI_unit
The most valuable feature that the DI box provides is isolation. That eliminates ground problems mentioned by Dennis.
