Loud electrical buzz coming from Apollo Twin USB

Hi all,

Looked through the forum and couldn't find this particular issue. Just bought an Apollo Twin USB and have it going directly into a Blade Stealth USB 3. I'm getting this ridiculously loud buzz. Looking deeper it seems the noise will shut off I unplug the USB cable from either the IO or the notebook. It's a brand new cable and the one UAD provides with the Apollo Twin.

Any insights into why this is happening and how I can fix?

Update - it seems it's coming from the charging cable being plugged in. It's 100% clean when I don't have any power feeding to the computer. May be a grounding issue and can try to lift the ground, but am scratching my head if that's really a long term solution. Any recommendations?
