Speaker Test
You can use this tab to test each connected speaker to ensure if 4- or 6-
channel audio operation works properly. If any speaker fails to make sound, then
check whether the cable is inserted firmly to the connector or replace the bad
speakers with good ones.
Select the speaker by clicking it to test its functionality. The one you select will
light up and make testing sound.
