Why can't I play media in a call on my galaxy s6?

[AC Question]

I can't watch YouTube videos or play music in a call and it's annoying.

No offense, but I'm trying to think of a situation where that type of multi-tasking would be useful. I can only imagine trying to hear the person I'm talking to while music or a video is playing. I would imagine there's a software limitation, preventing sound output from multiple apps. If you root you MIGHT be able to get around that but I wouldn't know the first thing about doing it.
