I've been working on an XACT class wrapper and have it working to the point it will play streamed music. I noticed the music is playing with a bit of a synthesized distortion effect on it. At this point I'm only loading the global settings, wav banks, and sound banks. Not sure why or how this is happening. I'm using Microsoft DirectX SDK (February 2010). Any ideas?

I found the solution in a post on a different site.

Since I'm testing my code, I played the sound via a key press. I don't have a condition keeping the execution of the key press from re-entering the same code. This didn't seem to cause any problems until I noticed the sound was off.
