NOTE!
All ThinkPads manufactured since the year 2000, have AC'97 or more recently HD Audio controllers. Those controllers are paired with a simple codec chip which are listed below.
If you have Audio problems with such a ThinkPad they are most likely due to problems with the codec support, not the AC'97 or HD Audio controller itself.
