No sound after installing Windows Version OS on Virtual Box

I installed windows 7 RC version on Vertual Box where host Operating System was ubuntu 9.04 (jaunty). Every thing was working fine except sound. I notice that Windows 7 giving error message "no sound device found". That was the major problem which I found after installing windows 7. I did some googling to find the solution of that problem. Some forum suggested to try Alsa-mixture, where as some other suggeting try OSS. But nothing works.
Finally I set my settings in Alsa-mixture and AC-97 audio controller. But this also did not works. But luckly I got the solution from Virtual Box bug report. For solution I downloaded AC'97 Audio Codecs from http://www.realtek.com.tw . After installing AC'97 codecs, Windows 7 automatically ditected sound. Now Windows 7 have full feature on Virtual Box and I am enjoying testing of Windows 7 on Virtual Box.

PS: Which software you have to download and instal

1. Go to http://www.realtek.com.tw

2. Click on "Downloads", then on "AC'97 Audio Codecs". On the downloads page I downloaded the file with the description "Vista/Win7 (32/64 bits) Driver only (ZIP file)".

3. Extracte the files and run setup.exe from "6303_Vista_Win7_PG537" folder.
