Can't stop AI radio chatter during scripted conversations with radio subtitles. These commands do not work: player setVariable ["BIS_noCoreConversations", true]; player disableConversation true; enableRadio false; enableSentences false; - if I'm missing something, do vote down and explain to me! But presently, I'm still getting voices like 'Area clear!' etc. Would be good perhaps, to get a new command. Something like setAITalk false/true...

Apparently, enableSentences works. But I tried 'enableSentences false' in a unit's init. line and I still got the 'area clear' voice (there was only the 1 unit on the map, so I know where it was coming from). It does appear to work most of the time, however.(I'm really sorry, Moricky, if I've missed something or have not fully understood the role of enableSentences false).

It'd also be great if this could silence radio command voices for the player. See: issue 16884. http://feedback.arma3.com/view.php?id=16884.
