I have the same problems on my iPad Mini. I was caught out initially by having the sound effects muted which caused the ring to be muted too although the visual alert did activate (not much use when asleep!).
There is a simple fix I think - Apple should disengage the alarm from all the other sound settings (do not disturb, mute etc) so that it ALWAYS rings if set. Leave the user to switch it on and off and that way we can have confidence that other iOS settings will not be inadvertently affecting it.
However today neither the visual alert nor the ring went off on a repeating alarm which as far as I can see is correctly set up. I think Apple have some work to do here because the clock and alarm is a basic and essential function.
The alarm app is poor on iOS. It's main problem is that it is too diffuclut to know how/if it is configured. I don't like Android but its alarm function and the 3rd party apps are miles better.
