Can confirm this is still an issue. Just this afternoon finally updated from 1909 to 2004 and immediately noticed the crackling audio issue. Google search found this thread, I immediately reverted back to 1909 and changed my group policy to ensure it won't update again until this is fixed.
The Razer Surround spatial audio is the best solution I've ever found and I refuse to go without it while gaming. Microsoft needs to fix this issue.
