Why? What's wrong with the on board sound?
You will need to add a sound card if purchasing the motherboard on its own. I would recommend an Envy 24-HT for this one as there are some known issues with certain CMI-8738 types of card
However given that Amigakit are selling this as a complete system it will come with a soundcard which has been tested and will be working so you shouldnt need to worry ;-)
