Digital Tone in Recording

I am having an issue where there is a digital tone being introduced into my recording. I seems to neatly hit on 2k, 4k, 8k, 10k, and 16k. I believe its a digital sound being introduce. Any help on this would be appreciated! I've tried uninstalling and reinstalling drivers, changing latency, changing cables. I believe its internal to the computer. While some of these changes may work for a bit, the digital tone comes back and in the case of changing the latency, different clicks are introduced causing me to have to go back to my original latency setting.
