Why is there no sound from the dash cam?

[Nadine]

If there is no sound from the dash cam, and the speaker is not damaged, it is usually a setting issue. The specific reasons are as follows: Mute is enabled: The settings page of the dash cam has a mute option. If there is no sound, the mute option may have been turned on. Solution: Disable the mute setting and turn the volume back on. Recording function is turned off: If you find no sound when playing back the video, the recording function may have been disabled. Dash cams usually record audio by default, but many people turn it off for privacy reasons. Solution: You can enable it in the settings interface.
