How can I setting when I click to play video then background audio auto pause and after play finish video auto play back the background audio? Becuase many client don’t know right bottom can stop the background music.
And when I play video A then I go to play video B, video A can auto pause?
The audio/video extension controls do not allow to setup such mode in which only one audio source is active at any time. Perhaps it would be better to start with audio disabled? This way the users will need to intentionally turn the audio on with the bottom menu button, and if they do so, they will know which button is responsible for controlling the audio.
