No sound on Instagram videos
I use an iPhone 5 and the sound for videos on my Instagram app isn't working. i have tried it on my 4S and also on my iPad and volume on both of those works fine. The switch at the side is on, my phone isn't on silent however I have just gone into instagram and played a video and if you switch to silent and then straight back on to 'on' straight away the sound then works on the video. If you go to replay the video I get no sound again. Surely this isn't right. Has anybody else experienced this? i have deleted the app and reinstalled, switched off using the home button and the sleep button and nothing, no volume on my Instagram videos at all. Could anybody suggest anything that I could maybe try?
Thanks!
