Hi, Just wondering if there is a way to mute individual apps. Ideally, I'd like to be able to be on a phone call (using the headphones) and continue to watch a video on screen with the video sound muted. Doing it with the iOS volume controls will mute both the video sound and the call sound. So is there any way I can just tell it to mute the video and not the phone call? I am jailbroken btw.
