There is no way, install another sound software and then make the sound file.

Do you mean "can't hear"?

The original driver and utility software for your audio hardware is likely available on the manufacturer's website in this order:
1. Computer system manufacturer (Acer, Dell, Gateway, Hewlett-Packard, etc.)
2. Audio component manufacturer
3. Motherboard manufacturer

If the necessary software is not available at #1, for #2 or 3 you will need to determine whether your audio component is a discrete adapter card or integrated onto your motherboard. If you would post your computer brand and model, I could better point you in the right direction.
