Caller audio looping back |
|
|
Hi
P4 3.0GHz, Win2000 Pro-SP4, Realtek AC97 Audio.
I have used NetMeeting flawlessly on the above PC for many months. Recently
I slotted my old Win95-compliant LifeView FlyVideo II video capture card into
the motherboard, and now my callers are receiving their own audio
transmission cycled directly back to them (after a short time interval
delay). Does anyone know how I can remedy this? (How-To URLs appreciated).
Thanks

Echo that your partners hear is caused by the setup at your end. I am not
sure how the video capture card is a factor though -- assuming you are not
using it for audio.
Are you using a headset? Generally the only way to eliminate echo is for
the echoing side to use a headset (the echo is usually caused by the mic
picking up audio from the speakers though it could be a misconfigured or
faulty sound card).
Careful placement of the speakers and mic and manipulation of output sound
levels and mic gain can also limit echo but finding an appropriate setup
and reproducing it is often problematic.
Many newer voip programs have software sound management algorithms that
attempt to eliminate echo (and many times succeed) but use of headset at
both ends is still the most reliable method.

Hi Brian
Thanks for your help. I solved the problem! I knew that the problem was at
my end, and you were correct that it was a faulty setup. I simply had to
access Volume Control and set it as per the following:
1 - Double-click SoundVol to bring up its main window.
2 - Options/Properties/Playback/set Microphone to Mute (this killed loopback)
3 - Options/Properties/Recording/set Microphone to Select (this killed
playback of my own transmission through my own speakers).
There are so many factors affecting the correct setup of a PC these days -
not just audio - that finding the solution now is complicated greatly.
I am using handheld mic and separate speakers; as you say, a headset is
probably a better solution.
Hope this helps anyone else with the same problem.
Thanks again Brian for your assistance!
