My only assumption is maybe there were changes in the previous ROM regarding AddMusicK. 256 bytes is not exactly large but methods to free that space is not without consequence.
Without the steps to accurately replicate the problem there is only so much we can do besides conjecture. For now, the simplest solution, is to change the following on Line 56.
You may notice a slight difference in quality but to most players/listeners it'll be negligible. Increasing the decay may help but that's beyond the scope of the question.
