I'm sorry for my bad English, but I believe that I know how to fix the problem with SoundMax AD 1985 on Windows 7 32 bits:
I had problem with my ASUS P4P800 with AD 1985 when I installed Windows 7 and after to search a lot on Internet and never found a solution I decided to try by myself and it's work now!
Attention: Obviously that you will need the Drivers
or CD instalation!
1º) Put the CD into the driver
or extract the driver and program intallation in a folder;
2º) Into the folder that have Win XP driver select the executable files (*.exe) and click with rigth button of mouse over them (one-by-one) and choose "properties";
3º) In the window that appears choose compatible mode, them choose Windows XP SP2;
4º) After doing it on every file "*.exe" go to setup.exe and run it!
5º) If all was worked well, the driver and program SoundMax will install and work without problem like Windows XP!
That is all!
One more time: Sorry for my bad English, but I think that the answer of the problem awards the effort!
