Realtek HD no sound - Windows 7 RC x64

I've got the same problem. I got a GIGABYTE motherboard GA-P35-DS4 with Socket 775, but there's two different rev. versions that I don't know the difference on. I've tried them both.
The first install worked(don't know what that version was), but after a few days of happiness over my sound working properly, I left my computer for a second, and the sound dissappears. I've tried both versions, uninstalled and installed, but nothing works. It has turned out sometimes, that I'd get my right speaker to work, but eventually it looks like the software doesn't seem to know, what input I'm using. One day I got it all working, but after some minutes the sound took off in small bits again(weird).
if anyone has the same problem, please answer and tell me what version I have to install, it's kinda getting me on the nerves.

Here's how I fixed this. I'm using a P45 DFI Blood Iron MB with Realtek onboard sound. I was seeing indications that the sound card was working but I received no output until I...

A) Installed the current drivers for 7 from the realtek site and...
B) Unplugged my speakers, moved them to a different sound port (didn't matter which one), and then moved them back to the speaker port.

Hope this works for you.

JColt, unfortunately there is no option like that. you can see below

Did you scroll down? It is 2 spot's below equalizer.

As you can see in this picture, the blue and green input in the right top and button is highlighted, as if an input was inserted. However I've only got my speakers jacked in to the one between, so I'm thinking.. bugged?

Yes, sure.

If your cannont install the Realtek HD Audio Driver, or it will not work after
installing the Realtek HD Audio Driver, you are advises to download the README of the driver.

Referencial web site:
Realtek

The README PDF tells us the Realtek HD Audio Driver does not support the ALC850. Driver for the ALC850 is the AC97 which you can download from the Realtek's website or the Station-Drivers:
http://www.station-drivers.com/page/realtek.htm

Please check your Audio compenece firstly, then install the correct driver.

Did anyone have luck finding/installing these damn drivers?

I have an Asus A8n-SLI Deluxe mobo and I am looking for drivers that work, for two months now. No luck so far.

My realtek HD audio works fine, it auto installed during setup like all setups had no problem since.

Mine works fine as well on the previously mentioned K8V-VM mobo. Have you verified that the digital output isnt listed as the default device?

Nothing changes if I uncheck digital output. Same result.

Already did that.

I have two devices with exclamation marks in device manager that I can't find drivers for. It's beyond me. I don't know what to do next. It's been this way with every build.
