Sure. But same can be said for pretty much any garbage collected system.
If you don't create objects or cause objects to become unreachable, you also won't be creating garbage. So you won't have GC pauses. Unless the GC system is braindead and runs even when there's no heap pressure.
With a stop-the-world garbage collector, allocations on other threads can result in your audio thread being paused, so you have to not be allocating objects on any thread, which is a significantly more difficult requirement than simply not allocating on your audio thread while audio playback is occurring.
