My computers sound isn't working

I have a HP ENVY TouchSmart 15 Notebook PC, all of a sudden my sound is not working on my computer after it did its daily updates.  I get a error message that says CAN'T PLAY: make sure headphones or speakers ae connected and that your computers sound card is enabled. With the code 0xc00d3fa (0xc00d3fa). 

Any help would appreciated in fixing this problem.
