Unsolved JW.ORG streaming audio doesn't work

[pablotto]

For this website the audio of video doesn't work...
In the previous version before 6.0 It worked.
All video start but audio no.
For example

https://www.jw.org/en/library/videos/#en/mediaitems/2018Convention/pub-jwbcov_201805_19_VIDEO

Thanks
