So the volume buttons on the side of my iPhone when pressed will bring up the speaker icon, but will not adjust the volume. I get no sound at all, unless I go into the iPhone app general settings and play with the volume there. The change volume with buttons setting is on, so I know that is not the problem. I have tried restarting the phone, I am in the midst of trying a hard reset, as much as I hate to do it. If that doesn't work, I have run out of options. Anyone have any advice on this issue?
Added (1). The sound settings are at the max, it's not that.
