Hi, is that the correct setup? Can you see the images? Minus of the piezo is open or connect with ground of soundcard? No extra power supply for transformer? Only from sound card?

i made a video.
I try with common ground for transformer and piezo minus, it goes stronger sound.
Should there be sound?
