Guys who play COD/WZ, I made some configurations that drastically improved my audio. Maybe this will also help those who are experiencing bad audio.
I couldn’t hear anything—an enemy could be dancing right next to me, and I wouldn’t hear a thing. Rarely, when the server was stable and the game was running smoothly, I could hear well! But that was rare—out of 10 days, only one day would have 4 or 5 matches like that.
That’s when I realized the audio isn’t processed locally on my PC. The enemy audio comes from the server. That’s how I managed to fix my problem:
First, I put my PC in DMZ (I believe manually opening the ports would have the same effect). Then, I completely disabled the Windows Firewall—not just through the normal method, but by disabling it 100% via Regedit, because using the standard method, Windows still keeps the firewall running in the background.
I believe this happens because, even when “disabled,” the firewall still blocks or delays some audio packets, preventing the game from playing them properly. Something like that must be happening.
It could be a placebo effect, or maybe I just got lucky with a good server, as I mentioned earlier. But I played all day, across different modes, servers, and locations, and the audio remained perfect.
I hope this helps someone else who’s struggling with the same issue!
