Just as a followup, that file gives you the chipset drivers.
After a reboot, you can check in Device Manager. Go to "System Devices"
and look for "Microsoft UAA Bus Driver for High Definition Audio".
If WinXP is SP1 or SP2, there are separate downloads from Lenovo, to provide
a driver for that item. If you're already running SP3 Service Pack, the
HDaudbus.sys driver is already installed.
You can use Start:Run and "winver" to check the system version, or go to
Control Panels and use the System control panel, to check the OS version.
So when looking at the Lenovo download page, you might want to consider one
of the following two, if you have SP1 or SP2 respectively.
"Universal Audio Architecture (UAA) High Definition Audio class driver (Q888111)
for Windows XP with Service Pack 1"
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-65440
"Universal Audio Architecture (UAA) High Definition Audio class driver (Q888111)
for Windows XP with Service Pack 2"
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-65456
If you have SP3, you should not need either of the previous ones.
Then, you can download the actual sound driver after that.
"ADI SoundMAX audio driver for Windows XP and 2000 - ThinkCentre A52 (type 8153, 8154, 8155,
8156, 8157, 8158, 8159, 8160, 8161, 8162, 8163, 8164, 8165, 8166, 8167, 8168, 8169, 8170) / M52"
http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-62612
(File =
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/thinkcentre_drivers/q4aud24us13.exe)
More instructions can be found in the "README.txt" inside the q4aud24us13.exe file.
The sound chip is apparently an Analog Devices AD1981. The Analog Devices driver
should be adding ADIHdAud.sys to the system. And presumably, after a reboot, there will be
a SoundMax entry somewhere in Device Manager.
