No sound when uploading video to Facebook

[AC Question]

I have recorded a few videos, and they are fine when watching them on the phone. When I then upload them to Facebook, there is no sound on the video when watching them...

Anyone have an idea how to get sound on my videos on Facebook?

Welcome to Android Central! Is this when they autoplay on your Facebook wall, or even when you click on it and watch it fullscreen? The volume is automatically muted when it first starts autoplaying, so make sure the mute is off.
