Video sound not working

Hi there,
I am running ELAN 5.9 on Mac OS, and one of my videos is not working. The video file was initially .mov and I could not play the sound on ELAN. I then realized that the sound wasn’t working on my computer either when I opened it with QuickTime player, but it worked when I opened it with VLC. So I first converted the file to m4v (with VLC) and then the sound worked when I opened it on my computer. But when I tried to open it with ELAN again (with the updated extension) it still did not work.
I checked the volume slider and everything is normal. I’ve always worked on .mov videos or .mp4 but it has never done that before. If you can think of a solution I’d be really grateful!
Here’s the logging message if it can help:

Thanks a lot!

Quick update: I changed the the preferences (Edit>Preferences>Platform/OS) and I ticked the “VLC Player Library” box, and it worked! If you ever encounter the same problem, it may be the solution?

Good that it works with the VLC player.
I assume that if you would convert the .mov file to .mp4 it would also work with the default player on macOS, but if the VLC based solution works well for you, then you can stick to .m4v.
