More information needed.

Update your post to include full system hardware specs and OS information.

Is the following product link a match to your dac?

Is this a new setup?

Was everything working as expected before the light switch was turned on?

Where does the light switch "fit in" with respect to the computer, monitor, network devices, and audio devices in your setup?

What is the overall connectivity being used?
