Translation:

Hello, I'm interested in knowing why my sonos speaker flashes red and doesn't charge, is it a battery problem?

Response:

It’s possible, although you haven’t told us which speaker it is. I’d probably refer to the LED states FAQ first, then I’d call Sonos Support directly to discuss it.

Respuesta:

Es posible, aunque no nos has dicho qué orador es. Probablemente me referiría primero a las preguntas frecuentes de los estados LED, luego llamaría directamente al soporte de Sonos para discutirlo.
