Uploaded clip to WhatsApp but no sound

The video clip in events was shared to people on WhatsApp. It’s important as it shows anti social behaviour. But there is no sound!

I read it’s a codex problem. Can I do anything about this to work around it!? Unfortunetly I can’t download any apps on my phone, to covert videos, because my phone has no storage space, I need to get a new phone eventually (I’m chronically ill and haven’t got round to it).

Seems so stupid Wyze hadn’t sorted allowing audio in clips to work on WhatsApp!

If you have access to a PC you can download and convert the videos there.

If you do not, there are lots of web sites that can do the conversion for you. Just search on “audio video converter site”.
