It has come to our attention that videos may not play with sound on mobile devices within LinkedIn. This is not just for Vaetas videos, but for any videos.
Here is how LinkedIn has responded in their help center:
"Sorry to hear for your trouble sharing videos via your iOS device with LinkedIn!
Following are some troubleshooting tips to try:
Log out of the application and then log back in.
Try restarting the device.
Check how much disk space is available on the device.
Alternate between a data connection and a wifi connection.
If the above steps don't work, try uninstalling and reinstalling the LinkedIn application on your device."
