Particularly this is the problem in busy airports, like Heathrow (EGLL). F.e. I'm loading with 707, and as soon I switch the battery on, AI speech system starts narrate all requests and permissions. Yes, my radios is not even switched on at this point. And if you start with enabled AI/MP and ATC in the sound configuration, disabling those options will do nothing (tuning the radio out of freq or switching it off do nothing too), at least immediately, as if like there is still messages in the voice buffer, and they _should_ be replayed at all costs. They'll stop eventually, but this is really annoying. And this is not how it should work, I believe.

upd. Most amusing part, is that in some cases narration starts with even battery off and sound option disabled.
