Follow the next steps to reset it:
1.- Open Voicemod.
2.- Go to the Voicemod Settings->Advanced settings tab.
3.- Disable the anti-popping mode.

- Open Start -> Settings
- Go to "System":
- Click on "Sound".
- Look for "Advanced sound options" and go to "App Volume and device preferences":
- Here, click on "Reset":
