[1.1.42, macOS] Popping noise caused by non-blocking save

[duskwuff]

If non-blocking-saving is enabled on macOS and the game is saved while a sound is audible, there is a momentary popping noise. Under some circumstances, the noise can be extremely loud.

This behavior first showed up when I upgraded to a new (M1) MacBook Pro with macOS 12.0. I didn't experience the same behavior on an x86 MacBook Air with macOS 11 -- but I'm not sure whether it's the new hardware or the new OS that triggered this behavior. This behavior does not occur if non-blocking-saving is disabled.
