Stereo 1/4 inch connector with Teensy connect question

Hey there,

I have trouble with connecting a 1/4 inch for an expression pedal to a Teensy 4.1

I use this schema, but there is no signal and when insert or pull out the jack, there is a power cycle, so the Teensy reboots.

The expression pedal is a EV-1
Now It's connected without any resistors used, but even with 10K resistors the power crashes with a plug insert or pull.

I tried mutiple configurations, but didnt have any luck.

Any GURU that can help me out with this one 🙏

Thank you in advance

Cheers 🍻
 
To whom might read this

The issue is solved. I did not need any resistors at all. Also 5V is not necessary 3.3V works just fine.

Problem with my connector is that it is switches somehow inside the connector. It gives a power corruption when I pull the jack from the connector. Need to buy new plugs but if I leave the plug in, it works perfectly so maby I will leave it this way


Cheers 🍻
