Basically title. A setting to only pause playback on headset disconnect in the case that the disconnected device was playing.
In my specific case, I'm playing music through an earbud and get in the car. I connect a USB DAC to the phone. Poweramp hands off audio from the earbud to the USB DAC without issue, but will pause when I put the now-silent earbud away, disconnecting it. I would prefer that it keep playing, because the disconnection didn't interrupt anything or force an output change.
The setting as it exists is good otherwise, and I'd like to leave it on, because I don't want music to come out of my phone speakers when I disconnect something that's in use.
