We need to know what sound card you have. The driver should be on the restore disk supplied with the computer, but knowing what Tiny computers are like, I doubt that it is. Any reasonable maker would also have the drivers on their website, but you probably won't find it there either. Try downloading and running SIW click here. This superb little utility doesn't need to be installed, it will happily run from a USB memory stick or whatever folder you download it to. It should then tell you what your motherboard is. If the sound is integrated into the motherboard we will probably then be able to find the driver.
