This is likely caused by having only an audio-only playlist and a high-bandwidth audio+video playlist. The short version of the problem is that the initial bandwidth calculation thinks it isn't sufficient for selecting the audio+video playlist, so it picks the only-audio one, which unfortunately locks it to being audio-only forever, preventing a switch to the audio+video playlist when it gets a better estimation of bandwidth.

We have an open issue for only allowing audio+video playlists when there are both audio-only and audio+video playlists in the manifest, but unfortunately, we haven't been able to implement that behavior yet. In the mean time, doing either of these will let you get around this:

• set the enableLowInitialPlaylist option -- this is the best option, since it should always select the lowest-bandwidth audio+video playlist for its first playlist
• set the bandwidth option to a value high enough to select the audio+video playlist -- for this media, the effect should be the same as using enableLowInitialPlaylist since there's only one audio+video playlist, but it's something you may want to keep in mind if you add more rates

It's also worth mentioning that Apple no longer recommends having an audio-only rate; instead, they recommend a very-low-bitrate audio+video rate. Removing the audio-only rate would of course eliminate this problem since there would be only audio+video playlists to choose from.

As you can see in this implementation
VideoJs Test HLS V4,
We have included the videojs-hlsjs-plugin and it works.
But without videojs-hlsjs-plugin if we set enableLowInitialPlaylist option to true still not work.

Looks like some wires got crossed. While @squarebracket's recommendation about the audio-only rate applies, the options are for contrib-hls and videojs-http-streaming, not for videojs-hlsjs-plugin which uses hls.js internally.
We don't maintain that plugin, I would look at the hls.js documentation and videojs-hlsjs-plugin docs for options that do similar things.
