Hi all

I have a site which is pulling in an mp3 as a background track which the users can switch off if they wish.

On a later frame I have a selection of external videos (3) which all have soundtracks that the user can watch.

My grief is this - if the user decides to keep the background track ‘on’ how can I fade it out if they decide to watch any or all of the videos?

Thanks for any pointers 🙂
