Well honestly
ACS is quite a mess of a engine, if you don't have RespectFilteringEnabled turned OFF in the SoundService properties it may or may not cause things to break.
Now turning this off isn't the BEST idea if you are trying to be exploiter proof, but ACS is ACS.
You would be better off rewriting most part of it or find a fork of ACS.
But if you don't want the trouble or just don't really care about exploiters, just disable RespectFilteringEnabled
I would still recommand trying to find a fork of ACS or even make your own fork as ACS is quite literally the worst engine ever in term of security.
Even our ACS is forked if you didn't notice.
