Dualsense rumble functionality does not work in-game. Using steam input works though in a very generic fashion. Upon research, I’ve fixed that issue by renaming my device to wireless controller rather than its original long name Dualsense Playstation 5 Wireless controller. I also have to make sure the audio is set to wireless controller and not muted.
I am not sure if this is isolated to Garuda, the game itself or is widespread?
