tracks pausing while opening other tabs/browsing

Not sure if this problem is stemming from the site or my laptop but I’ve always been able to listen to the jukebox in an opened tab while browsing the web but today it goes in and out as if on pause when I navigate away from the page. When I go back to the tab it’s in it automatically starts back up. Sometimes it continues to play and sometimes it just pauses for no reason and starts back up on it’s own and sometimes I have to go back in to the tab and it starts and sometimes I have to go back in and hit play again. I haven’t changed any settings and my laptop is only a few months old?
