Many countries? South Korea is the only one I can find a source for online. In Japan it appears to only be a voluntary choice among device manufacturers.

"voluntary" choice in Japan is basically the regulators telling the carriers that if they don't do it they'll have to regulate. From the carrier's point of view, it's a matter of doing it now in friendly terms, or doing it tomorrow with the regulators on their back.

How about Ukraine?

How do those laws address devices without the capability to produce sound?

The shutter sound can just be a beep as far as I know. One digital camera I bought for dirt cheap did that, presumably to cut costs.

By forbidding them, most likely.

So the law mandates a speaker, and logic to convert data to audio, be bundled with every optical CCD?
