line 406 is missing in section.php (audio for background video)

Hi there!
We love the video background, but I am confused about an option…
Referring to this post ( https://kriesi.at/support/topic/background-video-with-no-sound/#post-229951 ), we would like to edit the config-templatebuilder > avia-shortcodes > section.php (line 406) in order to enable audio.

You recently referred to this very post here as well: https://kriesi.at/support/topic/background-video-3/ but not here: https://kriesi.at/support/topic/is-is-possible-to-have-audio-with-video-background/

The problem is I cannot find the ‘video mute’ string at line 406, which, in my section.php file, appears to be empty. I cannot find ‘video_mute’ anywhere in the mentioned file…

We have requested a specific front end option here as suggested by you: https://kriesi.at/support/enfold-feature-requests/

Please help us. :)

Thanks for your willingness and have a lovely day.

Paolo
