Realtek audio, no sound. New notebook Accer extenssa 5220

Hello every one I have bought this new laptop ACER extensa 5220, it came with no operating system, I have installed vista everything seems to work fine.
But when i installed Windows XP Media edition all other drivers software when installed works fine But I have no sound, I checked on device manager I checked the device manager- Under sound, video, game controllers, I have audio codecs, legacy audio drivers, legacy video capture, media control, video codecs listed. I do have other devices, with PCI device with ??! listed beside them. I have updated the chipset driver and installed the windows xp drivers for my Audio_Realtek_v5.10.0.5423_XP high def audio codec. I have the latest direct x 9.0c installed with no luck. The on board audio is enabled in bios. Windows auto is automatically started in services. what else can I do?

the laptop specifications are as follows;
Operating System Microsoft Windows XP Media edition
CPU Type Intel Celeron 530(1.73gh,533 mhz fsb,1mb l2cache)
mobile intel graphics media acelerator
Audio driver Realtek

 

One PCI device is more than likely the MS UAA bus driver. For some reason, sound devices are not taking the back grade to XP well. I don't know why, exactly.
HP has finally released an update that is supposed to cure that on their PC's. (No help to you)

Try this:
KB835221 Hotfix
1. Remove "Audio device on High Definition Audio Bus"
2. Download from Microsoft the KB835221 hotfix and install it: KB835221 Hotfix http://h10025.www1.hp.com/ewfrf/wc/g...tem=pv-22533-1
3. Restart the system, and XP will automatically detect the devices
4. After this you should be able to install Realtek drivers.

 

well I did download the Microsoft KB835221 hotfix and installed it but still have no sound.what more can i try?

 

What is showing in Device Manager in the System section? Is the MS UAA Bus driver there? (It may be labeled HD Audio Controller) The UAA must be installed before the Audio driver

Also right click on the unknown PCI devices, click uninstall, then right click again and choose scan for hardware changes.

If that doesn't work,
1) In Device Manager, remove the High Definition audio device (or the unknown device, if there is one) under Sound, Video & Game controllers.
2) Go into Device Manager>System, right click the UAA Hi-Def Bus driver.
Disable the device and then uninstall it. (Do not re-boot yet)
3) Uninstall Realtek High Definition Audio Driver (you may just have a folder that says Realtek) through Add/Remove Programs (if it's installed but not working)
KB888111
In Add/Remove Programs, look for the KB888111 update and uninstall it. (It may have uninstalled in last step)
If you install, remove, and then re-install this update, the update is no longer listed in Add or Remove Programs in Control Panel.
Therefore, you cannot remove this update from your computer.
To work around this problem, follow these steps.
1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Locate and then click the following subkey in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Updates\Windows XP\SP2\KB888111 (may be in SP3)
3. On the Edit menu, click Delete.
4. Click Yes, and then exit Registry Editor.
Run CCleaner, both the Cleaner and Registry.

Reboot, but don't let Windows install the driver.
Install your driver, then reboot, again.

The UAA should be contained in this download.
