Recording don't have sound

[thuylinhdtl]

Hi all, my zoom records do not have any sound, neither video files nor audio files. I have turned my mic on, it still working and everyone still able to hear me. But only in the recording files there are no sound at all. What should I do. I have checked everything in setting.

Hello @thuylinhdtl,

Welcome to the Zoom Community! We're glad to have you here.

I'm sorry for the late response. If this has not been resolved yet, you can try this: 

If you have saved a recording in the .MP4 file format and you are unable to hear the recording audio, try the following:

1. Open the recording file with a different video player or change the default video player being used on your Mac or Windows device. Some video players have difficulty playing certain file types.
2. If the sound still does not play, it is possible that the mic was muted in the zoom app, the headset was muted, or the Zoom app had the wrong microphone selected. Perform an audio test before you start the next recording to ensure everything is working as intended. 

Let us know if you need further assistance.
