Volume Mixer 2 is a cydia tweak that allows you to control the volume of each media channel & output separately

Description: Volume Mixer 2 is a cydia tweak that allows you
to control the volume of each media channel & output separately, instead
of being able to change it only when that channel is active (Ringer,
Audio/Video for music, video and games, Phone Call, Bluetooth headset &
headphones). You can display all of the controls in the mixer at the same
time, or choose to hide the ones you do not need.

Several skins are included, in addition to stock iOS look (which you can
fully customize by changing colors of text, sliders and thumb grabbers).

You can configure it in Settings/Volume Mixer 2, and open it using any
Activator action. Default actions for opening are long press on Volume Up
button or tapping on the volume HUD – you can change it in Settings. Close
the mixer by tapping anywhere outside it.

Compatible: Supported on all iPhone,
iPad and iPod touch running iOS 9 or later. You can download for free if you
have purchased old Volume Mixer previously.
