You'd have to do some things inside the operating system, which means rooting, which means no repairs. There are some files that set max limits on earphone, Bluetooth, speaker, etc. They're usually around 70 or 80, and an increase of only 5 in the one you need the increase would blow your socks off. But check in the S7 forum at XDA Forums if you want to go that route. I don't have an S7, and playing in system files isn't something I'd want to give you without trying it first.
