Description of your issue, suggested solution and other information

youtube-dl.exe "http://www.rte.ie/player/it/show/centenary-30003958/10552342/"

The resulting file .flv has an issue with audio.
The audio is perfecly fine on the website.
But if you play the .flv file using VLC the audio is jumping more or less every 2 seconds.
This issue is everywhere in the downloaded file.
I tried downloading all three versions of the file using -f 0-0 then -f 0-1 then -f 0-2 but the issue is still there.
Try for example to play at 11:30 you will notice that the audio is not constant. It is more evident when there is a high pitch instrument playing.

Confirmed with VLC 2.2.2, while the same file plays well (no jumps in the audio stream) in mpv 0.16.0. You may want to report it to the VLC team.
