I'm waiting for this feature.
Would be great

It would help a lot so we could hear voices over chopper ambients.

This is a crucial issue with our server, as some people find the chat annoying, and turn off VCON. Then when an Admin is saying a global message, they won't hear it. This fix would be hugely helpful and much appreciated, thanks. *NOTE* This also means that you could have separate sliders for each channel, so you could, for example, have Global and Side chat loud, but group, command, and vehicle chat lowered.

this is a must have for most rp servers

This can improve RP greatly, because as a cop at a checkpoint, it is crucial to be able to hear what the civ players are trying to say.

This sounds conveniant

This is still an issue. It would be nice to hear people in direct without turning up the ridiculously loud sounds of every vehicle as well.

Just had my ticket closed for this ticket, and it's something that's 2+ years old.

Direct communication worked previously before 1.54... Now it's completely unusable.
