For Windows to be able to recognise the sound-card in your PC it must have driver software installed for it to work.
Sound-cards, like most other devices, require driver software to work properly. So if you are having sound problems and you have determined that its a software issue you may be able to get a suitable driver from Windows Update or from the sound-card manufacturer’s website. This will also make sure that you have the latest driver for your sound-card. Make sure you know the name, make and model of your sound-card to make it easy to find the right driver.
As a general rule, it’s important to keep all your PC’s drivers fully up to date so you might want to invest in some software to help you do this.
