Hi
I also tried with Paul's experimental driver:

Also, no difference. Any suggestion of what sound can produce annoying cracking to see if I can experience it ?

What do you mean by 'no difference'? Both has no problems or both has problems?
How did you test?
You can use the attached program for test like:
--- Code: ---kaidemo wav-file 2
--- End code ---
'2' means UNIAUD mode.
You can use any *.wav files in \MMOS2\SOUNDS\.

I test it by running a .mp4 file and applause.wav. Before changing the DLL and after. In my case I hear no difference changing the DLL or not. But my issue is that I had never been someone that can appreciate the sound fidelity of audio at low level.
I tried kaidemo.

It sound to me like a pause in applause.wav. But I don't see any difference on the system sound.
I think we need somebody else to try this. I will check this on real hardware (not the vm) possible on the weekend.

What's your player to play a .mp4 file and applause.wav?

System sounds don't use Uniaud APIs at all. Testing with it is irrelavant.
You should test with apps using Uniaud APIs such as MPlayer, VLC, fluidsynth, KMP and so on.
To test with kaidemo correctly, do like:
--- Code: ---1. Run kaidemo with the original uniaud.dll.
2. Replace the original uniaud.dll with the new uniaud.dll. You don't have to reboot.
3. Then, run kaidemo again.
--- End code ---
Nevertheless if there are no differences, you're lucky. It's fine to use the original uniaud.dll.

I tested the MP4 with VLC. I found no audio changes with the test uniaud.dll

Thanks for this instructions. I had tried it with kaidemo, and I hear no difference between the two .DLL. I guess I'm lucky here.
