hello everyone
some years ago, I used my sound card as oscilloscope, and I remember that I got good results, and that I saw square wave on the screen from an opamp based oscillator. I was using a coaxial cable with crocodiles for connection. I remember that I did this on my old PC.
these days I wanted to repeat this interesting experience, but I do not have same material that I had before, this timeI do this with my labtop, and I searched for the same jack that I used with soundcard (the old jack is the only thing that I found again) , and this time I connected it directly to crocodiles for connection. but the problem is that things does not work as before. I built a square wave generator and I tried to see anything, but nothing appear. here you photos of the cable:
any advices?

sorry, I solved. there was just short circuit inside the jack terminals
