Is there a way to play 2 apps that run audio/video concurrently (even though I'm only enabling the audio in one)? For example, not uncommonly, on OSX, I'll have video running of only passing interest, so I'll mute it, then play audio from another source. With PiP now in iOS9, it would be great to have something like a live game running in PiP, but muting it to play my own audio. Is there a workaround, with an app perhaps, to allow for this? Thank you for any help.
