Sound but no voices

Any idea what could cause this? I noticed it after swapping between two expansions but trying to isolate the issue in a separate project hasn't been successful.

Seems to be something to do with switching from a sample map with mutli-mics to one without...

I figured out the problem. When changing presets I was purging/loading mic positions, but for the sample map without multi-mics it was freaking out, so I prevented the purging happening when the sample map has only a single channel.
