Diagnosis
The touch panel is unresponsive, but the physical reset function is independent. You need to use reset method.
How to Fix It
Unplug the speaker from power. Wait 10 seconds. While it's unplugged, press and hold the center of the touch panel. Keep holding it, plug the power cable back in. Continue holding for another 15 seconds until you hear a sound. Release—the light will pulse orange, indicating a successful reset.
If That Didn't Work
If you heard no sound confirmation, the power adapter or cable might be faulty. Try a different USB-C power adapter and cable that supports at least 15W to ensure the speaker is getting enough power to complete the reset sequence.
Heads Up
A factory reset is the nuclear option. It removes the speaker from your Home app, deletes all settings, and breaks any stereo pair or speaker group. Use it only when setup or reconnection completely fails.
