Playing video - no sound, have to run sound volume completely down and then back up to get any volume
I have an iPhone 8 plus, wife has an iPhone 8. Both on IOS 13.3
Not sure exactly when it happened - but some IOS 13 update borked this. Both of us have the exact same issue. When attempting to play any video that is in Messages or in the Photos app - playback occurs with no sound. Sound volume is all the way up.
However, if you take the volume slider completely down, and then back up - we get the volume - for a while. Seems if the phone goes back to sleep we have the same problem again.
Soft booting restores sound volume - but only these two methods will restore sound volume.
Need a permanent fix instead of running the volume down and then back up, or rebooting the phone.
