[1.12] Low pass filter doesn't update

[Enlight3ned]

When you go behind blocks, I assume that sounds from the other side should get "muffled". There is nothing wrong with the actual effect but it only updates when you esc out to the options and back in. Is this intentional or a bug?

This is with the latest version

EDIT: Seems to only affect Immersive Engineering multiblocks
EDIT 2: Only affects IE Multiblocks that have continuous sound (ie. Crusher)

It's a byproduct of how Sound Physics works, it only evaluates the environment when the sound starts playing, so it's fine for relatively short sounds but for looping sounds it's not great. I added at some point a feature that continued to evaluate the environment but it was badly implemented so I removed it but I'm planning to reimplement it in a better way.
