Yeah that seems to be the issue.
You're not 100% right with the difference between non snapshot vs and vs created from snapshots.
The actual reason why user cant hear each other anymore is the encryption. So i guess you had voice encryption enabled on your snapshot, but not on the normal server?
BTW: Im currently watching the issue and try to recreate and fix it. (This can may also fix some kind of ping timeout after a few hours)
