Clean Install, Cannot get correct audio drivers

I apologize if this has already been discussed, I've just recently joined the forum. My main hard drive recently failed. I got a new one, reinstalled windows and got my graphics card and everything else installed, along with drivers. I cannot seem to get my system to get my audio back up and running. I have an XPS 420 running Vista Home Premium 64 with HDA 7.1 channel audio. I know I need RealTek but every time i try to install it, it doesn't "take" and just recognizes it as "High Definition Audio Device". Also, I had an IDT Control Center that came along with it. The drivers on my disc didn't seem to work, the only luck I've had is a Sigmatel codec but it doesn't appear to have everything that everything back to the way it was after the install. Any help would be insanely appreciated.

Did you get your Realtek from here?

http://www.realtek.com.tw/downloads...=24&level=4&conn=3&downtypeid=3&getdown=false

I didn't get it from that site,no. I used the Realtek located on my drivers and utilities disc. Also when clicking on the link, it sends me into an endless loop of link moved here and then I click on it and then go to accept the terms and continue and it does the same thing.

Some other info that may be helpful, When I went to install the realtek from the disc. Device manager told me I had two audio "devices". They were labeled " High Definition Audio Device". In order to get the Sigmatel Audio Codec that I had installed to work I had to disable one of these "HD Audio Devices" and it would install on the other.

I was able to download the 64bit file from there but was unable to upload it to this post
Follow the link, try clicking I accept then click HD Audio Codec not next and see if that works.
