NO SOUND

TECH SUPPORT

I HAVE AMD 1700 SOYO MOTHERBOARD WITH BUILT IN SOUND, WIN98SE.
WHEN I LOAD DRIVERS FOR BUILT IN SOUND CARD ON MOTHERBOARD.
WHEN I BOOT THE MACHINE THERE ARE NO ERRORS, DEVICE MANAGER OK.
THE PROBLEM IS THE WINDOWS SOUND ICON IS NOT THERE. I CANNOT ENABLE IT. I HAVE GONE TO CONTROL PANEL & MUSIC CONTROL PANEL AND CANNOT ENABLE IT.
1) WHAT CAN I DO ?
2) WHAT IS CAUSE ?

I HAVE REMOVE THE SOUND DRIVER IN DEVICE MANAGER AND REBOOT THE MACHINE.
SAME PROBLEM.
