I have verified that my client has acoustic echo cancellation enabled by subscribing to the publisher echoCancellationModeChanged event and calling publisher.getEchoCancellationMode(), however I am still hearing an echo of my voice. Any thoughts why this might be and how I can fix it?

igagen,

Can you give us some info about what machine and what browser you are running? Is this by any chance on a new MacBook Air?

Hi Ankur,

It's a new MacBook Pro with the Retina display. I was using the latest stable Chrome (21.0.1180.89).

Thanks,
Ingmar

Hello Ingmar,

I'm also using the rMBP

If you are opening the same application in 2 different tabs, one in which you are publishing and one in which you are subscribing, this is expected. The reason is that the there is some state that we cannot share across two tabs in order to properly negotiate the EnhancedMicrophone object in Flash. If however you are experiencing this echo inside one tab while you are publishing and subscribing to someone else, then this is a real problem. Please try this out and let me know.

No, I only have one tab open. I just verified again, and I'm still hearing the echo. My roommate who is on a Windows Sony Vaio running Chrome also, did not hear the echo on his end.
Is this issue specific to the new MacBook Pros?

Hi there - to clarify - you're hearing your voice; is your roommate hearing his own voice? Are either of you using a USB microphone?

[igagen]

Yes, I am hearing an echo of my own voice, delayed a few seconds. Both of us are using built-in microphones, not USB. My roommate did not hear an echo on their end. Also his room is far away, with the door closed and we can't hear each other aside from through the video. I am using a new retina MacBook Pro (Mountain Lion). My roommate was using a Sony Vaio (Windows 7). We are both using the latest stable version of Chrome, 21.0.1180.89.

Since you are hearing echo, the problem is in the computer of your roommate. Your voice is sent to your roommate but the computer and then it bounces back at you as echo.

I suggest the following tests:
1. Check again all the echo cancellation settings in your roommate computer.
2. Ask your roommate to lower the volume the speakers. This should improve echo cancellation handling.
3. If possible ask your roommate to use headsets. It should completely get rid of the echo.
4. If all the above do not help, ask your roommate to try an echo canceling software like SoliCall Pro.

Ok, I tried again with my roommate, and we checked the 'echo cancelation' option in his system preferences, but then he actually started hearing an echo, where before it was only my end. There is no echo cancelation setting on the new MacBook Pro that I know of, so I assume it's automatic.

I tested with my other roommate who is on an older MacBook Pro, and we got a loud screeching sound throughout the video session.

In comparison, I tried a Google hangout, which worked fine on all laptops without any configuration. Not sure what else to try, but if a headset is required to get consistently good quality results, this service will be much less useful to me.

Thanks for following up.
