Sound issues when the game hangs or loses/gains focus

[fgsfdsfgs]

Whenever the game hangs due to intensive loading or saving, some sound artifacts can happen, like crackling.

In the case of map loading, they usually stop happening after the loading is completely done.

After saving, taking a screenshot with PS + START, or minimizing the game to Live Area and returning to it, the same sound issues happen and can persist until the next time the game hangs or loses focus, as if the sound buffer falls out of sync with the internal mixer or something.
