There are so many different volume levels to configure in iOS that it’s not even funny. One moment you’re turning down your volume, and the next, you might realize that you’ve just muted your ringtone instead of quieting down your Now Playing volume.
iOS tries to be smart about how it configures volume depending on what you’re doing at any given point in time, but it’s far from perfect. Fortunately, a jailbreak tweak called Volume Mixer 3 by iOS developer VladMax offers users a higher sense of fine-grained and manual control over each individual volume setting present on their iOS device.
