Hola, hace una semana recibí mis Sonos Ace, el audio es genial, pero, hoy al usarlos me percaté que comenzó a sonar chillidos repentinos,¿será algún problema de software?  Son prácticamente nuevos y solo los hice cargar 2 veces.

Hello, a week ago I received my Sonos Ace, the audio is great, but today when using them I noticed that they started making sudden screeching noises, could it be some software problem?  They are practically new and I only had them charged twice.
