Many users have encountered no sound on .mov files issue.
▪ The audio for .mov files from my canon camera has stopped working in Windows Media Player. Video is fine. No error messages, just no sound.
▪ Since re-installing Windows 7, I have no sound from MOV files shot on my Canon from Quicktime, VLC Media Player and Adobe Premiere Elements.
▪ I have posted a handful of .mov files on YouTube. Half of the files when played on YouTube have no sound, though they are not marked as matching third party content, which I know can cause the audio to be blocked.
▪ I have a few .mov files which I am trying to edit with Lightworks, the videos play with audio when I view them on my PC but when imported have no audio.
There're many reasons for MOV files playing without audio on Windows 10/8/7, Mac, iPhone, Android, Windows Media Player, Windows Movie Maker, QuickTime Player, VLC, Adobe Premiere Pro CC, GoPro Studio, YouTube, Instagram, or other platforms. It could be a problem with the file itself, hardware, or software. Read on to get the fixes for MOV no sound issue.
5 Solutions to Resolve MOV Video Playing Without Sound
1. Check the volume and sound settings
You need to make sure the media player and the device you use are not set to mute. For example, if MOV file won't play sound on Windows Media Player, you need to check the volume and sound settings of Windows Media Player and those of your Windows computer.
2. Check the speakers and sound drivers
Make sure the speakers are fine and the latest sound drivers are installed. Your computer use driver software to send information to the sound card. Therefore, if the driver is outdated or corrupted, your player may be unable to play MOV QuickTime movie file with audio. So it is necessary to update your sound card drivers in good time.

3. Check the audio codec of your .mov file
A .mov file could use an audio codec (e.g., LCPM) that your media player, device, or the social media platform can't decode, hence it plays without sound. You have four methods to fix the codec issue:
1. Install the missing codec. K-Lite Codec Pack contains all the possible media codecs you need.
2. Update or reinstall your media player and then you may get the required codecs.
3. Try a different player. If MOV file plays video only in Windows media player, no audio, try QuickTime player, 5KPlayer or other one you like. WMP isn't a good choice for MOV video playback.
4. Convert the MOV file's audio codec into a compatible one with WinX HD Video Converter Deluxe.
