Audio delay completely out of no where. High end PC.

I already mentioned your audio routing. Think about it, you're using your Desktop Speakers & Headphones as a Audio Source. Device Timing has been disabled, but my thinking is the Headphones are lagging behind. I would remove the Headphones as an audio source....

Another possibility is the filters you're using are causing the lag.
