This is a known isue and ASUS is working on a sound driver for the chipset. Keep checking their site for driver updates. The board should all install with Windows 7 except for the sound drivers. Some people say they can install the vista driver and run it in vist or xp compatibility mode. The other thing you can do is pick up a cheap $20 Win 7 compliant sound card till the chipset driver issue is resolved.

try installing a sound driver for it again

I checked their website. Did you download the sound driver RAM2080 Win Vista x 86 15.02.2007 version 6.10.5337.0?

If so and it did not work it looks like you'll have to update the BIOS (BIOS update RAM2080 _only_ for MS Windows Vista 14.05.2007 version F0A. However BE VERY CAREFUL and follow the instructions EXACTLY, otherwise you may make the computer unbootable.

Try doing a repair install of vista.

I have been working on this for months and finally got everything including front audio panel going. First Download the latest realtek audio drivers available  from intel's website or go here and download #3 http://downloadcenter.intel.com/filter_results.aspx?strTypes=all&ProductID=2839&OSFullName=Windows%2A+XP+Home+Edition&lang=eng&strOSs=45&submit=Go%21. Next goto control panel and add/remove programs then look for realtek audio drivers that have been previously installed. Remove program if one is found. Then go to device manager (right click my computer, go to properties, Then hardware, then device manager. Click on the"+" in front of system devices. Find "microsoft uaa bus driver for high defintion audio". Right click that and select, "disable". Then right click it again and "unintstall" the device. This will allow you to install the audio drivers on your disc, or ones you have downloaded to install without an error message. Once done install your audio drivers and restart your PC and windows should start dectecting your new hardware. An installation wizzard pops up. Install the files needed yourself from a specific location, not a disk. It will ask for location of file name "hdaudbus.sys". That file is in C:/Windows/System32 folder. If it's not there, which it should be, just find and download that one file but it should already be there. I have done all this on xp home ed, sp3. I now have sound, and my front audio panel works.
