En las preferencias de sonido, en salida dice "dummy output" y no tengo sonido. Como tengo dual boot con windows 10 en otro disco, reinicié en windos para checkear el sonido y para mi gran sorpresa apareció el parlantito con una cruz roja y tampoco tenía sonido! Me parece muy, pero muy raro es que me afectó el controlador en Windows. Directamente no detecta un dispositivo de sonido, como si no tuviese placa de sonido . Estoy suponiendo que la solución para esto tal vez sea reisntalar mint, pero eso sería una opción demasiado drástica.
He probado algunas cosas que aparecieron en el foro sin éxito. Espero que alguien me pueda ayudar.
