my laptop does not have a base driver, it works when I activate the realtek driver but when i open it next time it gets back to the same problem of no sound coming out 

i therefore ask the team to help me fix the base driver

Hi:

The base system device has nothing to do with why the sound isn't working.

You need this driver for the Base System Device...

This package contains the Ricoh Media Card Reader Driver for the supported notebook models and operating systems. The Ricoh Media Card Reader driver provides support for the following media: Memory Stick, xD-Picture Card, MMC, SD, and SmartCard.

Your notebook uses the IDT audio driver, not the Realtek one and W8.1 should have installed the audio driver automatically.

The only suggestion I can offer would be to try the W7 audio driver from your notebook's support page and see if that work on W7.

This package contains the IDT High-Definition (HD) Audio Driver for the supported notebook/laptop models and operating systems.

W7 is the newest operating system supported in your notebook.
