HDA2.dll is a High Definition Audio wave driver for windows 3.1.

Remove emm386 from config.sys

Add  to system.ini 
[drivers]
wave=hda2.dll

Then add (activate.exe) to the startup group.

Tested on 2 and 3ghz computers.




2017 update:

When using Computers with less than 512mb of RAM, 
you will need to add hdatsr.exe to autoexec.bat.

If the computer has plenty of RAM, 
you can use control panel driver settings to specify an unused address above 512mb.


If HDA2.DLL does not find HDAICOUT.HDA, 
the driver will attempt to automatically configure the HDA.

If HDAICOUT.HDA is found in the main windows directory,
it will be read as 32-bit Hex commands to be sent to out the HDA.
Each line must start with $.
$000F0000;
