Libjitsi echo problem on Windows

We are developing VoIP client for windows using Libjitsi.

Has anyone faced echo issues on Win10 with Libjitsi?

We have applied following adjustmenets and it didn’t help

  1. AEC is enabled
  2. net.java.sip.communicator.impl.neomedia.audioSystem.wasapi.automaticgaincontrol = FALSE

Thanks
Michael
