Cancelling The Echo On Hdmi Monitors - Avaya Scopia XT Series Deployment Manual

HDMI compatibility
Important:
If the tone level is not constant but increases and decreases (the tone is amplitude
modulated), the HDMI monitor is incompatible with the XT Codec Unit or not set properly.
Audio standards compliance
You may experience audio problems when calling older endpoints that are not fully compliant with
more recent standards, and thus not able to recognize and manage recent audio protocols such
as Audio G.719 (full band).
Solution
The endpoint administrator should disable specific audio codec if there is any compliance issue
with older endpoints.
If configuring from the endpoint, you must first enable advanced configuration, as described in
Enabling Advanced Maintenance on the XT Series
1. Access the audio settings. From the XT Series web interface, select Administrator
Settings > Calls > Preferences > Audio. From the endpoint's main menu, select
Configure > Advanced > Calls > Preferences > Audio.
2. Disable specific audio codecs by selecting No from the lists.
3. From the web interface only, select Save.

Cancelling the Echo on HDMI Monitors

About this task
An HDMI monitor might insert a delay in the audio, causing an echo.
To improve echo cancellation performance with Microphone Pods, you can use the system's
automatic or manual estimation of the audio delay. You can also generate the audio delay
manually. Then you can train the echo cancellation to use the manual estimation as described in
this procedure.
If configuring from the endpoint, you must first enable advanced configuration, as described in
Enabling Advanced Maintenance on the XT Series
Procedure

Administrator Settings > I/O connections > Audio-Inputs > Echo canceller. From the
