Control panel has an additional option of a clean install. I did that and static persisted both on the driver version Windows automatically installs 10.0.1.0 (I think) and on the 10.0.1.4 that installs from the AMD driver software.
I swapped out with a 1080 and the sound is perfect. I can only assume that this is a driver issue or bad card. Since no one else seems to be having this issue then it's probably a bad card. Hopefully they can send me a different one to try.

Sound static really can open a can of worms. It could be due to latency spikes on your machine. I suggest googling LatencyMon, which works with win 10, and evaluating if your PC has high latency.
I ran LatencyMon and at first everything was fine. As soon as I played a 4k video from YouTube LatencyMon reported that my PC was having issues and was not suitable for real time audio. I did not detect any audio issues while LatencyMon reported issues as I'm still using the 1080.
That did make me realize that I was so concerned with the popping and static that I forgot to set the RAM timings. That plus running the CPU in creator mode is probably leading to a high latency situation which may be contributing to or causing the sound issues. LatencyMon no longer reports high latency using the same test scenario after setting the timings.
I'm going to use the system as normal for the next few hours to make sure everything is stable then swap back in the Vega 64 to see if this helped with the sound issue.
Thank you for your suggestion.
If you wonder why I deleted my post, it's because it can be difficult to determine what the issue is, then it inevitably leads to HPET on and off, along with various other suggestions.
