Cannot open wav file or play contents

Question

I'm attempting to blend multiple wav files into a single file. The output plays only silence in windows media player and can't be read in pygame. Here's what I did:

oh = scipy.io.wavfile.read('Downloads\\sounds\\OH10.wav')
sns = scipy.io.wavfile.read('Downloads\\sounds\\snshort.wav')
diff = len(oh[1])-len(sns[1])
spacer = np.array([0]*diff)
newsns = np.concatenate([spacer, sns[1]])
x = np.hstack((oh[1], newsns))
scipy.io.wavfile.write('testing.wav', rate=44100, data=x.T)

Basically I want two sounds to be combined into one. I added the spacer so that the arrays are of same length.

from pygame import mixer
mixer.pre_init(44100, 16, 2, 4096)
mixer.init()
mixer.Sound('testing.wav').play()

error                                     Traceback (most recent call last)
<ipython-input-306-6be10c568430> in <module>
      3 pygame.init() #turn all of pygame on.
      4 pygame.mixer.init()
----> 5 pygame.mixer.Sound('testing.wav').play()

error: Unable to open file 'testing.wav'

Make sure `testing.wav` is in the same folder as your python file, or learn about _"relative paths in python"_. — Kevin Welch, Sep 27 '19 at 01:02
It is in the right folder, the problem is the output array. I do not know much about audio engineering, mainly how arrays are encoded — Bugbeeb, Sep 27 '19 at 02:38
Have you tried ogg file format? Or making sure that the wav is uncompressed? — Kevin Welch, Sep 27 '19 at 17:15
