Stupidly Silly, It Works, Not My Idea
I was surfing like mad trying to find an answer to this issue. I need the phone to be able to ring outloud in case work needs to get to me at night, but don't want all the other sounds to wake me.
No luck until more surfing this morning. Wish I could take credit for it but someone else gave me the idea. Tested it and it works.
Take a headphone jack, you can even take an old one that does not work and cut off the jack. Plug it in to your iphone. YOU ARE DONE!!!!
Phone rings loud and clear. All else tries to play through the headphones. So simple, so stupid, so elegent, and it works!!!
