Yes, the internal speaker only has one volume level for playback.SJCam Official, you do not understand what I am talking about. When you replay a video on the camera screen, there is no way to adjust the volume on the internal SPEAKER (Not the microphone input level) during video playback on the camera screen. Your comment above states that there is an "audio/volume" menu and there is NO SUCH menu item on V1.15 firmware. There is a "Microphone Volume" menu that is used to adjust the microphone input sensitivity. This is not a volume control that is used to control speaker volume during PLAYBACK of recorded video.
