follow these instruction and it will work for windows 7


workaround to get the Stereo Mix in the record tab.
First download the latest driver and unpack it, probably at c:\dell\driver\R.....
open the folder i386 \ SMAXWND \ W2k_XP \ , it has a file in it called "ADIHdAud.inf" . Open this file with notepad and search for these 2 lines:
HKR,AD1983\\Disable, OutR, 1, 01
HKR,AD1983\\Disable, MonR, 1, 01
change the 01 into 00 at both lines so it looks like:
HKR,AD1983\\Disable, OutR, 1, 00
HKR,AD1983\\Disable, MonR, 1, 00
Now uninstall your sound drivers, reboot pc, go directly back to the folder where you uninstalled the driver (the folder with the R(number)) and run Setup.exe (it might complain that the files might not be genuine, if so ignore it), reboot after installation and you got Stereo Mix and Mono available. They both work perfect for me. What really blows me away is that if you look at the code in the inf file is that stereo mix is disabled ON PURPOSE, my question is why???
Also go to
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Cl ass\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0005\AD1983\Disable\
which had the two values: MonR and OutR... both set to "0000 01"
combined with the solution from this page, I simply changed those values to "0000 00" and restarted. Stereo mix and Mono Out are no enabled.

and reinstall audicity
