problema audio

[carpen]

Buonasera, è da qualche giorno che non funziona l'Audio nel mio sistema, nell'icona in alto a destra del desktop che indica il volume c'è una x come se fosse disabilitata la scheda audio, nella scheda audio sulle impostazioni di sistema nel riquadro che indica Riproduci suono tramite, non si vede la scheda audio.
