Audio issues on PSCX-ReARMed

I’m currently using the latest nightly (June 20th) on an iPad mini 1st gen, and am having trouble with a few sound effects. The background music is perfect and consistent, but some sound effects are cut off or just simply not there. When this happens, I drop from 60 frames to 59.5, if that has anything to do with it. Anybody else have this issue and manage to solve it?
