No sound from downloaded youtube videos

[ghost]

Hi, there is no sound in the videos I downloaded from youtube. Is anyone else having the same issue?

I used this command.

youtube-dl -ct -f 134 youtube_url

Tried playing the video with vlc and umplayer.

youtube-dl 'http://www.youtube.com/watch?v=UxxajLWwzqY' works fine, could you post the video urls and maybe the output for the available formats( run youtube-dl THE_URL -F)

For example I tried this.

$ youtube-dl -ct -f 134 http://www.youtube.com/watch\?v\=E6KwXYmMiak

Here are the available formats. BTW, does "Dash Video" mean it will strip off the audio?

$ youtube-dl http://www.youtube.com/watch\?v\=E6KwXYmMiak -F

Yes, formats tagged as DASH video only contains the video, while the DASH audio versions contain the audio.
Just run youtube-dl http://www.youtube.com/watch\?v\=E6KwXYmMiak and it will download the correct version.
