Audio only files guide

[brandonocasey]

Description

It would be really nice to have a guide for audio only playback. So that we can direct questions towards it

Proposal

1. Add a Guide to /docs/guides/audio-only.md outlining how audio only files can be played.
2. Update the FAQ to include this guide.

Good suggestion @brandonocasey. I was having the same issue and i did not know how to work with video.js iand audio files. I have to try other options. If you can help me towards this problem that would be nice.
