If you are using your speakers, make sure to select “Speakers” when entering a Via activity. We also strongly recommend that you install the latest version of Adobe Flash Player to suppress any return audio, or echo. Another very efficient solution would simply be to use earphones, for example those from an MP3 player; however, note that the sound of a Web camera microphone is of much lesser quality than that of a microphone integrated to a headset. For optimal quality, get a USB headset with an integrated microphone.
