laptop reinstall-->no sound

recently, my aunt got some random to reinstall her sony vaio

it's a jap laptop, model: VGN-SS54B/S with id: PCG-6H2N the back.

everything works fine except there's no sound. I'm quite sure the sound card isn't broken as the sony vaio music plays on start up and errors still emit the regular *beep*

I tried downloading realtek sound driver and it doesn't work.
tried downloading sony utility via google translation but also doesn't seem to help find sound drivers

I'm clueless as how to solve this problem now ><

can someone lend a hand please?

thanks in advance

 

bump?

 

If you have startup music your drivers should already be installed.

Do you have the speaker icon on the right side of the bottom taskbar? If you right-click it and select open volume mixer is anything muted?

 

there is no startup music, only sony vaio sound

and no, there's no speaker icon in the task tray

 

I was hoping that it was simply a muting problem since you had some sound. I'm not good with drivers so I hope someone else will jump in.

I think I would get your chipset driver (don't worry that the model is slightly different this should be the one for your system too) install it, reboot and then try the Realtek driver again.

 

thanks sach2 for the prompt response

however, that didn't solve the problem, sound device is still detected as non existent

the best guess I can come up with is that it's to do with jap laptop not accepting non-original drivers

 

Is there any yellow question mark in Device Manager my friend ? Follow this

Start - Run mmc devmgmt.msc - Ok

do it !! :wave
