Almot in my installation, i found the problem was into the SB Live! DirectMusic Synthesizer.
I made the tests on Direct X panel, and it is wich make sound bugs.
I move the hardware accelleration two steps back... and the quality one all back.
Then i go to my Audio settings and change the Synthesizer
from SB Live! Synth A (DF80) wich was using by default...
to SB Live! Sw Synth (DF80)
The good is it seems to solve the problem....
The bad is SwSynth means Softwatre Synthesizer...... is is acellerated by software, so it uses the CPU
Some times i hate this sim....
