Google Map No Voice

Recently, I finally found the root cause of the Google Map no voice or not talking issue. Although I made sure that it was not muted and crank up the volume all the way, I still could not get the navigation voice. So I lived with it. However, my wife's Android phone also has the same issue, so enough is enough.

My root cause was the media volume.

1. Press up on the physical volume button.
2. Select the 3 dots (...) highlighted.

3. Slide up the media volume highlighted.
Why can't Google/Android make it such that when you push on the volume buttons, you really want to bring up/down on all the volumes.
