I watch my races on my big screen - PC editing machine - with a professional sound system attached to it.
I leave my system at a high volume and I manipulate the volume through windows or software sliders.
The problem is when the race is loading, a popup AD jumps to the front AT MAXIMUM VOLUME and sometimes this is annoying (late at night or someone is asleep etc)
what I do; I figured to enter the AD controls and mute it but it takes 10 seconds .....
CAN YOU DEVS SETUP THE STARTING AD WITH THE SOUND MUTED PLEASE ???? OR WITH THE CONTROLS NOT HIDDEN ??
Because that makes GPRO run out of money :P Plus i beleive they have some sort of pop up asking you to turn it off, plus the adds are actually still there in the boxes, its just greyed out so it actually makes no difference
Your solution definitely solves the problem, but respectfully I would go the "muting the tab" route. I do use adblock throughout but I whitelist GPro since this is my way of contributing to the maintenance of the site/business.
