My speakers aren't giving bad any nouns?

I be uninstalling a few programs the other day, and next I restarted my computer. I opened up my iTunes, and I couldn't hear any nouns! Then I opened Windows Media Player, and it say that I might not have a nouns device installed on my computer. The speakers I currently have are the Logitech X-540. Yes, I've be to the site and no, they don't have the nouns driver for me to download. I've tried the whole system restore shtick, but I can't run back farther than yesterday. I've gone to the device manager and that didn't lend a hand me either...Any warning? ]:
