I randomly get colleagues complain of Echos on my slack and google meetings. They often complain that they can hear themselves and it has been distracting for them. I’m currently running the version 1.10.0 release4 on my RM10 using the 1.5.1 GLKVM app.
You can use earphones first. In our previous version, we disabled the microphone's noise suppression and echo cancellation, because these two features significantly degrade the microphone's audio quality. Perhaps in a later version, we will expose these two options in the foreground.
