Thanks for these postings! I have a Dell Optiplex 745 running XP with SoundMAX Integrated Digital HD Audio. The driver linked in the first reply wouldn't install for me, I just got the message "The audio driver files do not support your computer hardware". I checked out my existing ADIHdAud.inf file (in Dell\Drivers\R243724\i386\SMAXWDM\W2K_XP) and it lists AD 1983 and 1984, so I must have one of those chips. It also has no "Disable Stereo Mixer" lines, but it did have several "Disable, OutR, 1, 01" lines, so I changed them all to end with 00, saved the file, uninstalled the existing driver, rebooted, reinstalled it by running Dell\Drivers\R243724\i386\setup.exe, rebooted, and voila, I now have the Stereo Mix recording option!!!
