If the media volume control on your apple iphone 4s wont work and only does with headphones plugged in, then chances are that there is moisture or dirt on the outer connectors. 99.9% its usually the hardware that needs cleaning and not a software firmware issue at all. This is a common problem that occurs to most users and resetting the device back to factory settings usually makes no noticeable difference at all.
Follow the instructions below to quickly get the sound working on your iphone 4S once again before taking it down to a store.
1) Get a cotton bud and dip it directly into cleaning alcohol solution.
2) Cleaning the charging / dock connector located at the bottom, going upwards and downwards across the gold metal contact pins.
3) Now place the wet side of the cotton bud into the headphone socket and twist it around.
4) Restart your smartphone and check to see if the sound is now working on videos, games and apps.
