Hello, I'm connecting a webcam to a Fire TV Cube with USB OTG and developing and app. Permissions and access to webcam video it's OK but when asking permissions to access to the mic I get a windows to go to settings but nothing happens. I know may be access to mic used by Alexa might be restricted but I need to access unless to the mic to the camera as we are developing an app with video call functionalities. Obviously the app already works in Android phone and tablets.
We are trying to provide permissions with adb to try but it wouldn't be a solution for an end user app.
Any ideas ?
