I am updating my old Packard Bell EASY Note E1245 laptop?

I have no sound whats so ever!Did I ever have audio !!I cannot remember as it has been ages since I blew the dust off this machine!!Please help as I am hoping to hand it down to my young son who is already hard of hearing.Do I need to invest in some external speakers?If so, which would you suggest be the best.As with many of our kingdom folk,money is very tight at the moment.
