Uniaud for OS/2 & eCS

This is the development home for uniaud, the Universal Audio Driver for eCS and OS/2.

Share your success with Uniaud on our new SupportedHardware matrix.


The current stable binary release is coming soon.

The current unstable binary release is

1.1.4 RC6 released April 6, 2008

The debug build for this release is 1.1.4 RC6 debug

If you have HDA hardware, please try instead one or more of Paul's recent test builds, such as: July 16, 2008


Getting the sources

In addition to browsing the sources here, you can check out the sources with your favorite subversion client.

Keep in mind that, unlike cvs, tags and branches are ordinary directories in subversion. With the typical subversion respository layout, it is rather easy to checkout more than you probably intend to. To pull just the trunk version, use something like

mkdir uniaud32_workspace
cd uniaud32_workspace
svn checkout trunk


mkdir uniaud16_workspace
cd uniaud16_workspace
svn checkout trunk

To update your workspace with the current repository content, use

cd uniaud32_workspace\trunk
svn update

If you want commit access to the repository, contact Paul.

Building the drivers

Once you have the sources, building the uniaud drivers is relatively straight-forward. You will need the following development tools:

  • OpenWatcom 1.7a or later.
  • ilink 5.0 from IBM, or, if using wlink, you need lxlite to bring it down to size.
  • The DDK.
  • For ACPI builds, the ACPI toolkit.

Debugging and such

Since the drivers are under development, issues are expected. See debugging hints for a guide to techniques and tools that can make solving them easier (we hope).

Alsa Resync

Uniaud derives some of its functionality from the Alsa project. This mean we periodically resync our sources with the latest ALSA sources. This provide both aditional device support as well as defect fixes.
