When I talk with my friend on private voice chat, he hears me fine, but I hear an annoying echo of my own voice 3 seconds later. I use earphones and a built-in microphone at the top of my laptop screen. My operating system is Windows 7, and I am using the latest version of SL Viewer 2.6. Can I just adjust some settings to resolve this problem, or do I need to use a headset? Thanks!
