DirectX Audio

I have a huge problem.
I'm trying to play a game on my computer but whenever I start it up it's saying it fails to initialize DirectX Audio. I must've done something to it when removing programs in the control panel. Is there some way I can repair or get a new DirctX Audio system or something? I'm not good with this kinda thing so  could really use the help.

Dear asshole who fucked up my DirectX:

I hope you die. You had to stand there while I packed up my groceries and chatted happily with the cashier because I'd bought good food---even cheap meat is good when you guy fresh spices to go with it. I"m sure you think that you're somehow entitled to steal anything you can find because somehow you've been wronged. But consider this: this is who I am. You have just deprived me of one of my two methods of running graphic intensive apps on my windows box, and my only method of playing most windows games. I can feel the blackness sweeping in on me, a depression that a year of war somehow doesn't equal. In war people want to kill you. Evdiently your fellow citizens just want to screw you. I wonder if I were a young guy with muscles, a high-and-tight haircut, and the obvious look of a veteran if you'd have stolen their DirectX.

I hope you die. I have no way of using anything except 640x480 GDI in my games now, or of using my cards 3d abilities. That's what you did to me. That software component represented 1/3rd of Windows and was a necessity. I had it exactly one month. You'll probably pop he .dll files and use it to boast to all your shitty friends about the free DirectX you scored. I paid for that phone, and I hope karma tears you to shreds.

If anybody offers sympathy, I will scream. I want revenge. I want trial by combat. Oh, and by the way, Cub Foods? Tahnks for being so not helpful. There are assholes who steal, and then there are assholes who just shouldn't work with the public. Thanks bunches. I'll take it to corporate if I have to. I hate you.
