In most situations, the onus is on the ebook creator to provide media controls--usually with javascript. Sigil's qtwebengine will provide a very basic set of controls if none are provided. But I don't have the first clue which reading devices/apps might provide similar defaults. If you want your epub3's media to be playable on the widest variety of devices/apps, then you probably shouldn't leave the media controls up to rendering engine defaults. You should code the controls yourself. Unfortunately, that's not something Sigil will do for you.
You should also check epub3 specs to see which codecs are required to be supported by compliant epub3 rendering systems.
