Re-reading I see that you have check valves which probably satisfy the vacuum breaker requirement.
The vacuum breakers on my mix valves sat on top and had a replaceable gasket it.
Plumbking would be the expert here, but it is conceivable to me that you are hearing air being
sucked in if you have a vacuum breaker or check valve not sealing. If they are serviceable
you might try cleaning the seals of any deposits.
