How I solved Realtek High Definition Audio driver problem.
I have Acer Aspire 5720z. Recently I downgraded my Windows Vista to Windows XP Professional SP3.
There was no sound. As you may experience it yourself, I had problems installing Realtek High Definition Audio driver. After reading forums and trying things for 8 hours (with breaks) I did the following, which WORKED:
1. Install Windows XP SP2 (format the disk with XP SP3 in the beginning of installing XP SP2)
2. I tried to install the Realtek HD Audio driver for XP taken from here
http://www.realtek.com.tw/...
I got ‘install realtek hd audio driver failure …227’
3. Uninstall Realtek from the 'Add or Remove Programs'.
4. Disable the Microsoft UAA Bus driver for Hihg Definition Audio (In the Device Manager, System Devices)
5. Uninstall the Microsoft UAA Bus driver for Hihg Definition Audio (same place)
6. Restart the computer.
7. Install the Microsoft UAA Bus Driver for Hihg Definition Audio taken from
http://drivers.softpedia.com/...
8. Restart the computer.
9. After the restart Windows says 'found new hardware' - HDAUDIO Soft Data Fax Modem with SmartCP #2.
10. Unpack kb888111xpsp2 (taken from motherboard_driver_audio_realtek_azalia file downloaded in step 7) into a specific folder.
11. Direct 'Found New Hardware' wizard to the folder where kb888111xpsp2 is unpacked. It asked me for the Driver CD. The driver for the new hardware is installed (I don’t know from where: either from the folder or from the CD, but don’t care much now)
12. Check the sound - IT WORKS!!!
13. Install SP3. Check the sound - IT WORKS!!!
Remarks:
1. One of the K-lite codecs was installed at some step.
2. At the end I was not asked for the Realtek HD Audio driver. So Windows used the driver either from step 2 of the driver from the Driver CD.
3. kb888111xpsp2.exe was actually clicked somewhere
4. Possibly there is a more optimal combination of the above steps
Success to all of you how are about to solve the same problem. I just have joined a postdoc at one Uni before even finishing my PhD at another one (still the thesis has to be finished, printed and defended). So I have to work at both Unis at the same time. As you may imagine I don’t have much time now to study how to install stuff and tune hardware, etc. My computers just must work in this period of my life. Therefore, GOD BLESS ALL OF YOU WHO CONTRIBUTE TO THE FORUMS. This let me solve the problem. Cheers

Only i could see legacy audio driver.
I could not find the realtek audio
