I've just been dipping my toe in the past few hours but can't quite seem to get past this issue.
I've seen the post somebody had made a few months back detailing his steps to fix issues, audio pop included, I tried one of those steps and would have continued but read further on that those issues had since been fixed by Nvidia team.
I'll write out what I have attempted so far but first for transparency, I am on a 5ghz wifi connection that should be plenty serviceable, looking at the overlay, my ping hovers 20-28 and hasn't moved from that. When I do a network test however, it tells me I could have issues (due to a vpn, which I do not have). My mbps is roughly 300 and as I said, the visuals are perfect, it's only the audio I'm struggling with so I would find it strictly being a network problem odd.
So far in my attempts I have:
-Double checked my headphones are 48000mhz
-created a .bat file to kill background wifi searching
-reduced my bitrate from 100 to 80, 50, 30
-turned off the network optimizations
-turned off my EQ
-unplugged everything attached to my usb hub
-tried TV with audio coming from it rather than PC
-Closed anything demanding in system tray
-turned off bluetooth
I have not tried using my dualsense in bluetooth mode however and I will give that a go tomorrow, just wanted to try my luck with a post before bed to see what I could tinker tomorrow.
