In your link a guy mentions that he is on Arch Linux, and that he had a file called .asoundrc in his home directory.
He overwrote it's content with the following:
pcm.!default pulse
ctl.!default pulse
I am on Ubuntu 22.10 and I didn't have such a file, so I created it ... and it works! No lag in Resolve now!
Steps:
# touch /home/<user/.asoundrc
# gedit /home/<user>/asoundrc
paste in the following:
pcm.!default pulse
ctl.!default pulse
and save it.
Restart pipewire:
# systemctl --user restart pipewire pipewire-pulse
# systemctl --user daemon-reload
Voila - no more lag in resolve (at least on my system)
