Test new UNIAUD audio driver build please!

July 16, 2010 by

Hello everybody,

I'm sending this email on behalf of David Azarewicz and Paul Smedley. David has been doing a lot of work on the UNIAUD driver to clean out none properly working source code. We would like to ask you to download the current build of UNIAUD. With the new builds older builds of
UNIAUD32.SYS will also no longer duo to required changes in UNIAUD16.SYS. Hangs on HDA hardware should happen in no way anymore. A lot of memory allocation routines have been cleaned up and improved. UNIAUD also has buffer _under_ run recovery. Which should improve video playback in genereal and people using the Emperoar TV application ( ):

Some of the recent improvements:
* Audio and video synchronisation with this build should be much better
then ever before.
*Overwriting memory, no boundary checking was sometimes done, now it
*Updates to the code that scans the PCI bus.

But as with all of these changes we do need people to test UNIAUD, get your build here:

Grab the latest beta package:
"The latest BETA release is 1.9.3 / 2.1.0: "

If you have UNIAUD installed on your system you can copy UNIAUD16.SYS and UNIAUD32.SYS to your MMOS2 direcyory and reboot. If you run into problems please open a ticket on SVN.NETLABS.ORG/uniaud For opening a ticket see this scetion on the website "Submitting Tickets"

Some people have bene reporting that there system sounds are repeating, like for example the startup sound is played and then its played again, completely. This is not caused by earlymeminit=true in the config.sys or ACPI or the SMP kernel. We are working on this and it somehow seems related to qrymmcd.exe in the config.sys. A semaphore from MMPM.DLL seems to be getting mixed up. We are working on locating this.
