Instagram video sound won't work on my iPhone? Help!?

[217]

My sound won't work for the instagram videos. It works for listening to music and watching videos on other apps but not instagram. I can hear the sound if I log into instagram on the computer but not my phone. Did anyone else have this problem? And if so, how do you fix it? Thanks a bunch!

Your phone can't be on silent.

if u look on the side of your phone where the volume button is there will be a little button type thing and it will be orange a little bit and just slide that button up at it should work
