Irregular noise is included in the sound of any game when running on my iPhone14ProMax #430

I noticed at the time of 2022.4 version and updated to 2022.5, but the same issue occurred. I had no issues with my iPadPro3G12.9inch. Both OS are version 16.2. When the emulation starts, the initialization sequence for each system board begins, which is often noisy. Normally, the noise stops when the initialization is over and the game starts running, but in the case of the iPhone, the noise continues. The game sound itself seems to sound normal, but at the same time there is a hum and intermittent noise mixed in.

I have seen the sound system do weird things over different builds, but have not pinned anything down. A few builds ago I made sure unused parts of sound buffers were filled with silence. But that was not it.

I think we may have a threading issue in the way the core lib is built, but I am just guessing at this point.
