ACER Aspire 4520 driver issues

Hi,
Recently, I reformat OS to Windows 7 Ultimate, 32-bit.
I'm using Acer Aspire 4520.
I had the exactly same audio problem, I did the same solution that you mention above.

i) Disabled and removed High Definition Audio Controller.
ii) Uninstall the Realtek driver via Add/Remove programs.
iii) Reboot my OS. (uninstallation requires to reboot).
iv) Install the Realtek driver (downloaded from your link above).

But still "No audio device is installed".

My device manager shows that the driver Realtek High Definition Audion with yellow sign. The properties of the driver shows error "This device cannot start. (Code 10)".

I believe it is not hardware problem, the audio works just fine before it was "gone" last few days. I'm so clueless.

Is the Windows Audio Service enabled? It should be set to Automatic and Started. Are there any other devices with the yellow exclamation mark?

Yes, Windows Audio Service is enable.
Realtek is the only device with yellow mark in my device manager.

Did you try the audio driver from Acer's website for Win 7 32bit?
