No More Heroes has major audio stuttering post AX- HLE

The sound stuttering occurs when the music is playing or during the attacks after the enemies do their exploding or splitting animations from being killed in the game.

Pre AX-HLE the audio sounds perfect no matter what, to get a better example of what I'm saying enter the first level of the game. Kill some of the enemies and the stuttering begins

This happens on LLE too.
3.5 works perfectly but the revisions after which tinkered with the audio messed it up.
