Ao falar no TeamViewer ou qualquer outra coisa usando fones de ouvido, eu costumo jogar som no fundo.
O problema é que o que eu estou falando pode ouvir o som de fundo.
While speaking on TeamViewer or anything else using headphones I usually play sound in the background.
The problem is that the whoever I'm speaking can hear the background sound.
You are probably using skype to talk to them. Make sure you disable your sound in teamviewer. In ur settings, on your computer disable the sound from teamwiever.
If you are using TeamViewer to talk to another person, you shouldn't be able to hear them.
