[SOLVED] OS/2 Warp 4.52 VM, changing audio to Uniaud

[Martin Iturbide]

Hi

I'm playing with some Warp 4.52 VM. It had the SoundBlaster working with, but I want to test to change it to Uniaud with Intel HD (on VirtualBox).

Problem: I installed the UniAud drivers (Uniaud-20220807-beta.exe), added them on the config.sys, changed the VM to use Intel HD as audio, but I get no sound.

I remember that someone once post a trick that you have to update also some INIs to make that kind of change.  Am I remember correctly? What was the trick?

 Hi Martin,

 You need to edit your MMPM2.INI file to use the new driver. Minstall is what normally does that. First you have to remove the Soundblaster driver using Minstall (tell it 0 cards to remove), then install UniAud using Minstall. Or do it by hand, but it is very tricky and can cause your system to not boot if not done right. Adding/removing sound cards on OS/2 is a true PITA.

Thanks David.

I will try with MInstall first. Are you referring the one from Martin Kiewitz or the IBM one?.
 
It seems that modifying the INI directly, with all the stuff it has there, it will be long and hard.

 Hi Martin,

  The IBM one... the Kiewitz one always gave me problems when trying to uninstall, but it works well to install. Definitely hard to do by hand... if you have trouble, post your MMPM2.INI file and I'll take a stab at editing it it for UniAud... if you like to live dangerously :-)

Hi

After some tries with the IBM MMInstall, I need to ask how to uninstall it.  I don't know to which path should I point the mminstal (or which driver to download) to put 0 card to remove sound blaster.

If I remember this correctly, you need to install 0 instances of your current driver. So you need to know what your current driver is, and you have to have the installation files.

Or you could try the uninstall that I once wrote and that is part of a uniaud install.
It will take file cardinfo.dll as a base of what to uninstall.
So, even if it was written for uniaud, you can use it in conjunction with the SB drivers. You just need to run it from the directory where the SB installation files are located. That should contain a file cardinfo.dll.

 Hi Martin,

  Look in the C:\MMOS2\INSTALL folder. There should be a folder with the SoundBlaster install files in it....

thanks to your post I have remembered what to do to complete the installation of the Uniaud; running the exe installer of the driver wasn't enough then.

@Martin , with the successful installation now I hear the system sounds but just that. If I run a video either from web or media player I only hear a rippy noise and video play very slowly making Seamonkey (in case of web streaming) almost unusable.

Hi mauro, you need "SET KAI_AUTOMODE=DART" in your environment (config.sys is simplest) to force the Mozilla apps to use DART rather then UNIAUD for sound. UNIAUD is broken as you found.
Edit: Actually the set command should work for any program using libkai for audio.

Hi Martin,

  Look in the C:\MMOS2\INSTALL folder. There should be a folder with the SoundBlaster install files in it....

Thanks for the feedback, but I don't find nothing (control file or SB files) on the install folder.

I guess I need to find some SB control.scr file somewhere to do the uninstall with MMOS2.

Hi Dave, in my config.sys I had the two active call sametime
SET KAI_AUTOMODE=DART
SET KAI_AUTOMODE=UNIAUD

so I tried to REM one first, then just one/other, then both.
Rebooted system on each change.
Nothing happened, system sound ok but no audio from video clip.

I believe there is some issue with Virtualbox audio filters.
Thank you

PS in the other UNIAUD thread I read Paul is continuously updating the drivers, I keep using a version downloaded on beginning september

Hi Martin,

  Strange there is no folder with the soundblaster drivers... I guess you will have to find the original driver package and use that (maybe at Hobbes - or on the OS/2 Warp disk you used?). Open a command prompt, navigate to the folder with the soundblaster install files, then run Minstall there. Use '0' (zero) for the number of cards in order to remove it.

Hi

I installed the Warp 4.52 Sound Blaster driver when I created the image with the "Warp 4 Setup and Installation". I search on the CD if there was the Sound Blaster driver alone with the .scr file and I was not able to find it.  Any other tip?

Hi Martin,

  Without the install files, you are pretty much stuck with trying to edit MMPM2.INI by hand, unfortunately.
