No Vibration Over Bluetooth But Rumble Works When I Plug The Cable In
Your hardware is fine. The DualSense exposes its rumble and haptics over USB on a PC but not over standard Bluetooth, so no browser can trigger them…

Haptics And Rumble Test Engineer at Gamepad Tester
Tests both rumble motors and haptic patterns, and finds which one has actually failed.
Camila works on vibration and haptics, with a background in audio and signal work that transfers directly: a rumble motor is a frequency-and-amplitude problem, and the difference between a weak motor, a flat waveform and a browser that is not sending anything is audible and measurable before it is visible. She tests both motors independently, the DualSense haptic layer and the adaptive triggers, across the connections that support them and the ones that silently do not.
On Gamepad Tester she owns the vibration test and the rumble faults topic.
