Recently i changed my motherboard, installed the cd (drivers, bios etc) and now when i start my computer, it says, found new hardware 'Microsoft UAA Bus driver for High Definition Audio' when i click next to install it, im told that microsoft hasnt tested it to be safe, i click install anyway, and it eventually asks for 'hdaudbus.sys'. which i cant locate.

My sound works fine. But if i dont have the 'Microsoft UAA Bus driver update for High Definition Audio (HD Audio)' am i missing out on HD quality sound?

What ive tried!

support.microsoft.com/kb/888111]Universal Audio Architecture (UAA) High Definition Audio class driver version 1.0a available for Windows XP, Windows Server 2003, and Windows 2000[/url]
This hot fix was not for my computer (i was told this after i installed it)

In device manage under system devices, i dont have ' Microsoft UAA Bus driver for High Definition Audio' available.

So, should i have that UAA driver? If so where can i get it? or is the installation wizard that come up when i reboot an error?

Many thanks guys.

When you switch out motherboards it is best to reinstall windows to avoid driver conflicts & registry errors so I suggest that you back up your data and reinstall windows. As for high def audio, I believe that you have to a special converter box to use it.

Thanks for the reply. What or where would i find a special converter? Is it software or a stand alone set up?

Many thanks.

Hi, Just another question. You mention reinstalling the OS, however, my oroginal comp was a dell dimension e521, with a new motherboard, how do i take it back to the factory settings? I have no cd as it was pre-installed, nor do i have a recovery disk.

Just want this system clean and operating at its best!

For 'hdaudbus.sys',,,,,,,

View and Download the MS Hotfix near the top of the page.

There in lies your problem. Sorry I forgot about this but the point is that it was, like you correctly put it, a dell. It no longer is a dell so your dell disk will not let you install it. You will have to obtain a new OS. If you want to still use windows through Newegg you can buy an OEM copy of XP for $90 (home), $110 (MCE), or $130 (pro). You can also get a Vista OEM if you want however I've heard that with the OEM version of Vista it can only be activated on one computer and isn't transferable to another computer. I don't know if that is true but I wouldn't put that past M$. Congratulations you now have a "custom" systems with all of the advantages & disadvantages. A disadvantage is that you can no longer use a manufacturer's windows disk but must resort to getting your own. You can try to continue running it as is but I don't know how long you will be able to; I would expect problems to arise.

As for the converter, my guess would be a high end audio store. I've never looked into and I don't know if it would even be worth it. So I don't know how to answer you on that.

Sorry, I missed the statement of;
