Description
Every audio and video source element should have a valid type attribute.
The type attribute allows the browser to select a media source without downloading media to test if the format is supported. To see this in action, compare network activity for [simpl.info/video/noautoplay](https://simpl.info/video/noautoplay) with [simpl.info/video/notype](https://simpl.info/video/notype).
To test, check that every source element for every video or audio element on a page has a valid type attribute.
