Ok, I though similar issues with Win XP on other notebooks with new HD audio from Realtek.
The point is that you need SP2 and SP3!
The SP2 and SP3 provides important fixes and patches for HD audio…
So first of all uninstall the installed Realtek audio driver.
Then install the SP2 and SP3.
Then go to the device manager and delete the devices marked with yellow exclamation mark.
Then reboot the notebook.
Now Win XP should found a new audio device and should ask for the driver.
No you should install the sound driver from Realtek.
Reboot once again… and now the sound should works fine…
Thanks for this fast help.
I do the steps you told me, but when I install the Realtek Audio Driver, they don`t install the driver for the Modem on High Defintion Audio Bus.
The Agere HDA Modem Driver don`t work, too.
Try this patch from Microsoft: Universal Audio Architecture (UAA) High Definition Audio class driver version 1.0a available for Windows XP, Windows Server 2003, and Windows 2000 http://support.microsoft.com/kb/888111
Additionally I recommend installing the Modem driver from Toshiba page
Then go to device manager and remove the devices marked with yellow exclamation mark once again. Remove the sound card which you can find under sound, video gaming controller too and reboot.
Otherwise you could remove the SP3 from the system and could try the MS patch once again. Then install the SP3.
I do everything what you told me.
I had removed SP3 and installed the Hotfix. After this I install the Audio Drivers -> No Sound.
Yes this Thread is very interesting and I done all thing they say, but nothing worked.
Just one question: did you try the newest Realtek sound driver which is available and could be downloaded directly from Realtek page?
Do this! Try the newest version…
Furthermore does the yellow exclamation mark appear in device manager even after the installation of the MS fix?
Yes, I use the latest driver from the Realtek Page.
I have only one yellow Question Mark for the Fingerprint Device, but I think this doesn`t matter.
I have the same Laptop in the office with the same settings and drivers and there is sound. I can not make an image from the other Laptop.
