Echo Cancelling on HDMI Monitors
About this task
An HDMI monitor might insert a delay in the audio, causing an echo.
To improve echo canceller performance, you can use automatic or manual estimation of the audio delay
by the XT Codec Unit.
You can also generate the audio delay manually. Then you can train the echo canceller to use the
manual estimation as described in this procedure.
