sine.set_voume isn't working

[cwrightlibrary]

Just installed pysinewave and I'm a huge fan so far but I'm having a problem with sine.set_volume not working. I'm not sure if I'm just not using it correctly but here's the code I'm using:

import time
from pysinewave import SineWave

note = 12
vol = 30
sine = SineWave(pitch=note, pitch_per_second=20)

sine.set_volume(-100)

sine.play()

time.sleep(1)

sine.set_pitch(+14)

time.sleep(1)

sine.set_volume(-10)

time.sleep(0.5)

while True:
    sine.set_pitch(+1)
    time.sleep(0.075)
    sine.set_pitch(-1)
    time.sleep(0.075)

Originally, I was going to change the value of the volume with decibels from 30 to 20 or something similar just to test it out but it wasn't working so I went to extremes and tried 0 for the input as well as what I have above.

I'm using PyCharm to write my code on a M1 MacBook Air.

My bad, I just realized I need to add the decibels_per_second line in the SineWave.
