After 11 years, nobody responded to your post. Here now in 2020, I have the same problem. I bought a set of 2.1 pro media computer speakers directly from Klipsch in March of 2020, and they worked great for two weeks. Then, all of a sudden, the subwoofer developed a loud hum. This noise is present even when the speaker system is not connected to the computer. As long as the speaker system has power, it makes this noise. If you turn the volume all the way down, the noise almost goes away. I sent a request for help to Klipsh through their website two days ago, but I have not yet heard back. This seems like a ground issue, but the power plug is not a grounded plug. Does anyone have an idea how to fix this?
