I have a Windows machine connected to an NI Komplete Audio 2. The NI box is connected to a set of Eris 3.5 monitors. It all worked fine for about thirty minutes playing some quiet audio, then the speakers tossed out a very loud burst of static and are no longer producing sound. The power light is on.

Audio is definitely flowing to the NI Komplete: I can connect a pair of headphones and hear sound; I can plug the outputs from the NI into different speakers and hear sound.

The monitors are definitely not producing audio: A pair of headphones plugged into the Eris headphone jack is silent. I don't think I have anything to test as an aux in, at least not laying around. Cranking the volume all the way does nothing.

I'm not sure what other troubleshooting is left. Did I get a lemon? These monitors are brand new as of yesterday.
