JavaでLWJGLを用いてOPENALで音楽を再生した際、異常な音が鳴る

Question

JavaでLWJGLというOpenGLやOpenALをまとめライブラリを用いてOpenaALで音楽を再生した際、やたら高速に再生される、ノイズまみれに鳴る等、異常な音が鳴ります。原因はDLLやPC環境に問題が無いという事以外、原因不明です。再生する度に違う音がなります。数値の部分をいじっても、全く解決できません。
一体どうすればいいのでしょうか？

以下がコードです。

LWJGLとはまた別のラッパーであるJOALを使用して無理やり修正しました。
結局LWJGLでOpenALが動かないのかは原因不明です。
