You misunderstood what I was and still am trying to accomplish. I know that I can adjust the volume using the side buttons. That's not the problem. Let's see if I can explain it better:
I want to be able to preset volumes for different things and have their levels remain static and completely independent of any volume adjustments I may make using the side buttons. If I set a volume of 30 percent of range for my morning alarm, 50 percent of the range for my phone ringer, and 65 percent for iTunes, and 40 percent for messages, I don't want them to change unless while I'm using them I change the volume manually.
For example: While listening to music I manually adjust the volume up to nearly the max and leave it there when I close the music app. The next morning when my alarm goes off, it goes off at the 30 percent I preset it for, even though I left the volume turned way up for the music I was listening to, which was the last adjustment made to the volume. This is what I'm trying to accomplish with my question posted here. I don't want to have to remember to turn the volume down when going to bed to ensure that it isn't too loud in the morning when it goes off. Conversely, I don't want to have to boost the volume again when my phone connects to my car radio to stream music to it via bluetooth because I had it turned way down for the alarm that morning. You see? Sounds to me like this would make a great app for someone to develop or a cool new feature for Apple to add in an iOS update. Thanks.
