1594185 - Firefox does not play sound on .ogv video although automatic playback for audio and video is set in security preferences

Status: RESOLVED WORKSFORME

(Core :: Audio/Video: Playback, defect, P2)

Description

[Ulrich Moser]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:70.0) Gecko/20100101 Firefox/70.0

Steps to reproduce:

I uploaded an .ogv video to my website and it plays perfectly on the notebook I used for production of the video. Starting the video on another notebook I see the video but there is no audio. The video can be watched at https://zpk-moser.de/index.php/coaching/coaching-blog/72-projekt-coaching-01
The production machine uses Ubuntu Mate 16.04 while the two notebooks that cause the problem run on Ubuntu Mate 18.04

Actual results:

I went to preferences - security and privacy and activated autoplay for audio and video and then audio works but when I leave firefox and go to the video again I have silence although in the preferences it still says autoplay audio and video. If I save the preferences again audio is back. When I jump back to the intro there is no intro sound it only comes back as soon as the content starts.

Expected results:

After I activated autoplay for audio and video videos shall always play correctly with sound.

This bug is more than 3 years old and does no longer exist. Tests with current versions of Firefox work well.
