Hello, thank you for reaching out! So after running the Clean Boot test, my game was running fine. However, I could not isolate a program(while following the steps provided) that was causing the audio delay. I then tried the clean boot again and I noticed the audio delay was still present.
Edit: I did notice twice now that while it was loading the anti-cheat, sometimes it paused and gave me a pop-up (I forgot what it asked). When I accepted it, I noticed in the firing range that I did not have any audio issues. I was only able to replicate it twice (once when I first ran the clean boot, and second time randomly when i re-enabled all my start up programs). I am not sure if it was relevant but it might be useful information. Thank you again in advance!
