Why is there no input sound while using AM350 with VibeEngine in Microsoft Teams?

Please try the steps below: 

1. Turn off “Monitor Microphone Sound", as marked in the red box blew. This option must be turned off because the microphone sound can be wiped out by Teams’ echo cancellation. 
 
2. If Headphone Monitoring is necessary, select “Microphone Sound” as marked in the green box below.
