Question / Help Microphone Issues

Mulwarp · Jan 14, 2016

Hello.

How can I get rid of the audio echo - without disconnecting the camera (which also records audio)
I have tried various settings without any luck - even "muted" the audio on the red "audio" bar in the main window, there´s still a high echo when music is played but muted on the main window...:

Post your full log and instead of "current log", you can use any one of the dated logs of when you recorded or streamed.

Remove the mic option from the webcam video capture device and add the mic to the mic/aux dropdown in audio tab.

Also if you are using speakers, don't. use headphones will isolate the audio
