I'm trying to get sound on Dark Souls: Prepare to Die Edition for the PC, however it won't work

Here is the background. The sound worked perfectly fine about two days ago. I had a few friends over, and decided to plug in my loudspeakers rather than my headphones. I set that up, and then play the game, audio is working fine. After they leave I use my headphones again without any issue.

Today however, using my headphones I tried to play the game but alas had no sound. I restarted my computer, and tried again, still no sound on my headphones. I plug in my loudspeakers, set them as default, and then start the game, and I get sound coming through my speakers. I then close the game, unplug the speakers, and reopen, but there is no sound on my headphones. I also tried to set them as default and restart again.

TL;DR My Dark Souls was working good on my headphones till I played it w/ speakers, now it will only work on my speakers.

I have generic speakers and Razer Kraken 7.1 Headphones.

Generic speakers use both a 3.5mm and a USB where Razer is solo USB.

I'm on Windows 8.1, playing Dark souls Prepare to Die Edition from Steam.

After a reinstall, I believe I went into task manager and closed Kraken APO Sys Audio Launcher and that fixed the issue.
