Q: Why several video formats (e.g. 1080p) have no audio?

A: Now, Youtube uses DASH to delivery audio and video separately. It also stops storing video and audio as a single file for some resolutions. FastestTube can download the files that are actually present on Youtube's servers only, so it downloads video and audio as separate files for those reasons.

But you can still download audio and video as separate files and merge them in the single file. Please, refer to this article for further details.
