Are visual Effects(Particle) Camera Dependant and switching cams Will Always have Problems?

Ok so i decided to add 2nd cam to my player. can switch views.by pressing key

i have some Denotations which are created with particle stuff( PS they are the free Denotation system in the Asset store).

I noticed if i explode some of my detnoation objects (triggered by colliding with them) it works. but then if i switch camera, the rest of the detonations that do explode if i dont switch cameras, no longer explode.

even the explosion sound seems to go wacko if i switch cams. like the sounds that do sound with one camera, dont sound with another.

I do have an AudioSource and listener on both cams.
