Am I going crazy or was I able to hear the sound on YouTube videos when my ringer switch was turned off, but now with iOS 8, the ringer switch must be turned on in order to hear the audio on YouTube videos? I thought my new i6 was broken when I played YouTube videos from Facebook (so far the only way by which I've tried watching videos) and I was getting no audio. Just for yuks I switched the ringer switch to on, and audio started playing. Definitely never had to do that before. Is this a new "feature"?
