Every time i go into a server without the headset-icon, i can't send any voice messages to my squadmates when using the squad com channel, but i can hear them just fine.
The local voice channel however is still working no matter what server i'm in. I haven't got a headset(i am using headphones) because my microphone is build-in since i have a laptop and so do my speakers.

Does someone know how to solve this problem?
