El audio no funciona en la computer. Tengo una Emachine E725 y una partición con Windows 7 y Linux Mint Ulyana. Se escucha el sonido exterior, pero no se graba interiormente el sonido en grabación de pantalla. No se si es un problema de Hardware o de solfware. Adjunto la información del sistema de la partición Linux Mint.
