+	 *   Playback is normal
+	 *   Playback immediately stops after the non-pow2 buffer
+	 *   Playback gets distorted on the non-pow2 buffer
+	 *   The entire program segfaults.
+	 * The workaround is to always specify a power of two buffer size
+	 * and hope that SDL_sound always fill it. (By lucky coincidence,
+	 * I already submitted the Ogg fix.) However, this won't catch
+	 * cases where a loop happens because the read at the end of the
+	 * file is typically less than the buffer size.
+	 *
+	 * This fix addresses this issue, however it may break in
+	 * other conditions. Always decode in buffer sizes of powers of 2.
+	 * 
+	 * The HACK:
+	 * If the buffer is short, try filling it up with 0's
+ 	 * to meet the user requested buffer_size which 
+	 * is probably a nice number OpenAL likes, in 
+	 * hopes to avoid a possible Loki bug with

+	 * that it may take longer for the loop to start
