Poor Audio during video / audio conference
Poor Audio / Echo during video or audio conferencing.
If you hear your own audio back as echo the problem is likely originating from another person. If the situation is reversed, then the echo is likely coming from your side. Mute your mic if you are told the other side has an echo or ask the other party to mute their mic if you hear the echo to check it that improves the problem.
If you are using external speakers, place the speakers far away from the mic and reduce the volume to a comfortable level.
For those who have external microphones, move the microphone about a foot away from the speakers. Avoid typing when using an unmuted mic and step back from the mic when using hands-free mode. You can also reduce the volume microphone level to 50% or less and reduce or turn off the microphone boost option.
Some computers have an echo cancellation feature but it could be compromised on high CPU load. Closing all un-needed programs can help reduce that load on the computer.
REBOOT your computer if you still have problems.
For Skype users, make sure to have the latest version of Skype downloaded. Skype has built-in echo cancellation which detects and reduces echo.
If none of these options are successful, use a headset or headphones instead of speakers. This is an easy way to get rid of audio problems.
Adjust the speaker on the codec.
Adjust the speaker volume on the monitor.
