TRS cable no sound for arduino

[Willtcs]

I build a edrum with arduino UNO, I have tried to use single piezo connect to the stereo jack on the breadboard, it's working and sound great. But plug the TRS cable to jack then it's no sound. Do I connect wrong wire on the TRS jack? Or I should change to TS cable and jack?

I have tried the TRS with/without ring and it's still not working

Do you have a schematics for that?

Some jack sockets have a switching function. When a plug is connected it lifts the spring-loaded connectors which make the connector conduct signal only to a portion of pins. Seems to be the root of the issue here
