audio driver problem

i have a problem with my audio driver. i seems that when i put my laptop to sleep by closing the lid it removes my audio driver and the icon with the speaker says "no audio devices installed" when highlighted. I have been fixing this problem with system restore but it keeps happening and i do want to keep system restoring. can someone tell me whats wrong with my laptop

Try downloading the latest drivers for your sound card.

That may not fix it,but it`s the first thing to try.

to be honest, that is not alot of info on your laptop to tell you how to help it, but do like Po' Girl said and download the latest software for you system
