No Audio

Hi I recently upgraded from XP to Win7 and everything is running fine except I have no audio.
In Control Panel it is telling me - "No Audio devices are installed"
In Devise Manager under sound, video and game controllers, I have Realtek AC'97 Audio with the yellow exclamation mark on it.
When i click on the driver details I have drivers listed -



When I try to update the driver i'm told - "The best driver software for your device is already installed. Windows has determined the driver software for your device is up to date. Realtek AC'97 Audio"

System details below -

Computer Type ACPI x86-based PC (Mobile)
Operating System Microsoft Windows 7 Ultimate
CPU Type Mobile AMD Athlon XP-M, 1600 MHz (8 x 200) 2800+

Any help will be really appreciated as this is really annoying me now.
Thanks.

Is this a clean install of windows 7?

Try reinstalling the drivers from this site.
Realtek

Yes it is a clean install and I've tried that link already.

Ok - tried that link again just incase and its still the same.

Your system specs list this as the audio device:

"Audio Adapter Analog Devices AD1888 @ SiS 7012 Audio Device"

Why are you loading in Realtek drivers?

Look here.

SiS - Welcom to Silicon Integrated Systems Corporation.

I was loading Realtek because thats what's listed in Device Manager.


I tried this link you provided - SiS - Welcom to Silicon Integrated Systems Corporation.
Just getting this again -

did you ever find a fix for this?

I had too run windows update and the proper driver was their the same problem happened too me then in control panel -> sound
select Realtek Digital Output and select it as you default device and plug you cable into the green plugin slot in the rear of the pc

Have you installed the motherboard chipset drivers? If not, give that a try and then Vista/Win 7 sound drivers.

Try downloading a new Realtek Driver from here:

Realtek

Choose from the list. I suggest you choose the one listed Vista, Windows7 Driver (32/64 bits) Driver only (ZIP file). I was able to fix my audio problem by installing this driver today!!!
