Hi, I installed google chat/cam. I can hear the other party. I can see the other party. They can hear me. They can see me. I however cannot hear them. Upon going into Settings and SOUND I noticed the output volume being muted. Would this have been the reason I wasn't able to hear people? When muted I plugged in headphones and couldn't hear any "static/friction." When I unmuted and plugged in my headphones I could hear the cord being inserted into the computer -"static/friction." I went into Google and made sure everything was set up properly on that end. I did the check. I could see myself. The computer was hearing me and I could hear the test sound I had to click on. What else could I be missing? I'm asking because I'm not exactlyl sure what the OUTPUT SOUND is. What is it for? I mean it makes sense - sound going out but that confuses me because people can obviously hear me (sound going out). Thank you for any advice.
