Reland audio: Add addtl permission sync behavior

This relands f81b2de4fdf649c47d3b335530571c70a4e266ed.

Serial based sysprop listening likely fires spuriously: attempt to add
barrier logic to existing cached property listener. Since CachedProperty
isn't thread safe, we will need to check the sysprop directly and add
some locking.
