Don't hear other players (wot) win.7

Hello, I didn’t find a topic. I had to create a new one. I don’t have a sound in voice communication, I don’t hear platoon players, only green flashes by nick during a voice, but there is no sound. In the settings, everything is turned on, there are checkmarks, the volume is high, but not audible. Please tell me what needs to be done so that I can hear the platoon players? I’m not asking about the microphone, if that, I don’t have it, I just want to hear the negotiations in the platoon. Thanks.
