Realtek Audio: No Audio Output Device is Installed

[deeptrouble]

Hello.

Im having the dreadful "No Audio Output Device is Installed" problem on my realtek audio.

It worked some months ago, but im in no position to do a roll back. Im sure the hardware is just fine, it works with Ubuntu.

The computer is a Dell Vostro 430.
My OS is win7 64bit.

I tried the newest Realtek driver suite, the recommended dell-drivers and some basic windows-drivers. Nothing makes the "No Audio Output Device is Installed" go away.

Any help is welcome.
Ive attached my sound-related reg. I believe my realtek device is 0001.

The Dell driver is required, non Dell drivers will either not work or not work correctly.

First thing, is the Integrated Audio enabled in the BIOS? (F2 at boot up to enter Setup).

Second, on Dell's (and many others) if the motherboard chipset drivers were not installed, the sound device will not work. In this model there are Intel motherboard chipset drivers. Try installing them and then the Dell sound driver. Dell Drivers

Thanks fireberd!

Yes. Integrated Audio is enabled in BIOS, and the audio works fine in Ubuntu. I believe my audio problems are entirely software related.

I (re)installed the Intel chipsetdrivers and afterwards the realtek audio driver. Both drivers picked up @dell.

The problem remains the same.

If it's not a driver issue then it's an Operating System issue. But, I have no idea how to fix the OS without a complete reinstall.
