Agh, why didn't I think the problem was with my headset?! I've been wracking my brain for the last few days trying to figure it out, and I finally found the fix. Turns out to be a really easy one too. I tried switching from my headset to my speakers and noticed that the voice acting actually worked on my speakers. I looked on Razer's support site for ideas on how to troubleshoot my headset, and I came across this entry on how to reset to factory default (http://www.razersupport.com/gaming-audio/razer-megalodon/). Well, turns out it did the trick! Just thought I'd throw that out there for anyone that gets a similar issue.
