My volume is at 100%. My Ringer and Alerts slider is at 100%. When i test the volume slider in Settings -> Sounds, it plays loudly. If I pick any sound category and test the sound it's super quiet. All system sounds on my iPad Pro are very quiet and I cannot get them play as loudly as the slider volume test. App sounds, music, movies, etc are all fine. It's just the sounds like "Text Tone", "Sent Mail", "Send Mail", etc... I've tried rebooting, etc... anyone else have this problem? No other issues on the Pro. I'm loving it.
