sound does not generated on jetson tx2

[xoxoxo13102020]

I am using ubuntu 18.04 with jetson tx2 when I use these code snippter on my python program

import numpy as np
import sounddevice as sd

fs = 22050

sd.play(wav, fs)

it does not work? Could anyone has any idea why?

Could you please try adding this line in the very end:

sd.wait()
