Right now, I'm adding a rudimentary sound engine to my game. So far, I am able to load in a WAV file and play it once, then free up the memory when I close the game. However, the game crashes with a nice ArgumentOutOfBoundsException when I try to play another sound instance.

Specified argument was out of the range of valid values. Parameter name: readLength

I'm following this tutorial pretty much exactly, but I still keep getting the aforementioned error. Here's my sound-related code.

The exception occurs on line 156 when I am playing the sound:

source.SubmitSourceBuffer(buffer);
