rp4 dolphin controller problom

Hey, I have an RP4 non-pro and my controller works fine in PPSSPP and RetroArch but has zero input in Dolphin and Brawlhalla. Buttons register in the system gamepad test, tried Xbox controller style in handheld settings, tried Mantis Gamepad Pro, tried remapping with both Android/0/ and Android/1/ devices in Dolphin, nothing works. Any ideas?"
