yes, try but don't be sure that it will work!
2 ground make a circuit, however all the circuit must have only one ground.
I just ripped off the ground in the power plug of one of the 2 speakers.
If you have more speaker or a more complicated setting, be sure that still the ground that make the noise but look at the good side! Fast track, monitors, pc and everything works good =)
Hope you can fix this boring problem mate
