Volume notification no control

On iPhone, adjust the sound volume of media, alerts, and sound effects using the side buttons, Siri, or Control Center. When you're on the phone or listening to songs, movies, or other media on iPhone, you can use the buttons on the side of your device to adjust the audio volume. Otherwise, the buttons control the volume for the ringer, alerts, and other sound effects. You can also use Siri to turn the volume up or down.
