No sound from YouTube video when iOS on silent

It is normal for sound to play when playing YouTube videos in browsers or in apps when the phone is on silent - however this doesn't happen in the inappbrowser, as such I'm needing to add a warning instructing users if they hear no sound to un-mute the phone - please can there be an option to allow audio from the inappbrowser even when the phone is on silent.

Start by reproducing YouTube playback in the iOS InAppBrowser while the phone is on silent, then review how the plugin handles audio in that state. Define the option's expected behavior and verify that enabling it allows audio without requiring users to un-mute the phone.
