Can't comunicate with ATIS, Tower ecc

[teoandrigo]

Hi!
I'm new in Flightgear.
I can't listen and I can't comunicate with ATIS.
How can I switch on radio in Boeing 777?

I already place the correct frequency of airport but It doesn't work.
Thanks
Matteo

After selecting the correct channel, you have to activate the mic button of the corresponding radio (L, C, R) on the captains radio stack. Hit Ctrl+C to light up clickable buttons, you have to press the correct volume button to enable/disable listening to it.
