Sony VAIO Aptio Bios Integrated Peripherals

After re-installing the drivers on my neighbor's VAIO for his Intel Display Audio which stopped working after a screen replacement/repair (showing as "no installed sound output device"), I went into the Aptio bios to check if the integrated audio had simply been turned off, I could find no Integrated Peripherals option under the advanced menu. Does Aptio simply not allow for advanced settings or is there a bios update for this [censored] that enables the Integrated Peripherals menu???

Thanks in advance.
