I am using Jitsi Android App in a Samsung Tablet with an external speaker plugged in Tablet’s headphone output 3.5mm connector. So, during jitsi call, the sound from remote person is reproduced on external speaker. The Acoustic Echo Cancellation cannot avoid the Tablet’s microphone to capture sound from remote person, and the remote person hears its own voice (echo).
How can I avoid this echo? It seems Jitsi is not using echo cancellation when using the external speaker.
Thanks in advance.
