The pulse jack on Hysteria is an output, not an input. Look at the manual. That's why I told you to use the gate to trigger the ADSR envelope, and then use that envelope to control a VCA.
In the earlier thread, you were told to turn down everything as much as possible, either using a VCA from the modular or the input gain control on your audio interface. Eurorack voltages are higher than line audio, and some devices will have trouble with it. What audio interface are you using, how are the cables connected, and how is the power supplied to everything? What happens if you unplug the switched-off modular?
