Good afternoon, all! I just got an iphone 7 plus a couple of days ago, and am having a strange issue. My ringer volume is set to 100 percent, and when I play music, that too, is played at 100 percent volume. Unfortunately, notification sounds, such as my chime app for time announcement, as well as the lock sound and other push notifications, are at a very low volume. I've tried turning off audio ducking, but this doesn't seem to help. I have tried to turn up the volume when sounds like this are playing, but I'm usually not quick enough as most sounds are very short, not to mention that pressing the volume buttons interrupts the sound. Does anyone have any ideas what might be causing this or how I can fix it? I have VO volume control in my roter; remember there being a weird issue with that when I first had my 5S, and I had to reset my phone to fix it. I hope that this isn't a similar issue. It seems that the vo volume is working exactly as expected, so why the volume of notification sounds is so minimal is difficult for me to fathem. Any suggestions you may have would be extremely appreciated.
