I’ve got working Nvidia drivers without any tinkering. Gaming on my 3060 without issues. Never had microphone issues either. This isn’t supposed to be “You’re wrong”, more a “I wonder what I’m doing differently”.
ASUS TUF GAMING B550 MoBo, AMD Ryzen 5600x, some Gigabyte version of the RTX 3060, running the Nvidia version of Nobara (Fedora-based gaming oriented distro).
