No sound on videos

Can you post a link to a page where this is happening, so we can see it for ourselves?

See as long you can’t embeded different video format. You try to load the video as wmv extension and it is not supporting with modern browsers.

Take a look into the above link to find the info of supporting video format.

I would say try to upload your video in youtube or vimeo and link back to your video tag.

Hope it helps

Thanks,
