Can you specify which android device and microphone model you're working with there?
Are there any audio preferences available to choose from in the GoToMeeting mobile app settings?
the Android device is sold by WorldTradeDisplay, the model is TMLPF-5503-R, it have a Rockchip RK3288, 2gb ram, Android 7.1.2, Linux versione 4.4.143. The microphone is integrated in the webcam, it is a Logitech C920.
In the GoToMeeting mobile app i have not found audio preference, can you help me to check?
I'm not familiar with that device, and was unsuccessful at looking it up online. Although I haven't seen external webcam hardware used with Android mobile devices I will see if it is possible to integrate the two together.
