Debugging breaks sound output

## Description

When debugging an application with the Firefox debugger, the sound output of my pc gets weird as soon as I hit a breakpoint and hover over a variable in VSCode (to view its value).

What happens to the sound:
- it's distorted
- random noise
- there's an echo ~1s later

This problem appears since I've upgraded to VSCode 1.47.0 (though I don't use it often while playing music, so the problem could have started sooner).

### Environment

- VSCode Version: 1.47.0
- OS Version: Fedora 31

## Steps to Reproduce

1. turn on some music
2. Add breakpoint
3. Run app and debugger
4. trigger breakpoint
5. go into vs code and hover over a variable / parameter to see the value popup
6. notice that the music just got buggy

## Additional information

I've noticed that the following new devices appear in the sound settings

En el issue no se identifica ningún archivo de código fuente ni ninguna prueba. Primero reproduce el problema con VS Code 1.47.0, Fedora 31, el depurador de Firefox, un breakpoint y el hover sobre una variable mientras se reproduce audio; después rastrea qué interacción del depurador coincide con los nuevos dispositivos de sonido. Se considera terminado cuando la depuración y la inspección de variables ya no distorsionan, retrasan ni repiten con eco el audio del sistema.
