When the user plays media remotely, and presses on the volume keys with the screen off, verify whether not only local playback is active, but also if remote playback is active to see if the volume should be adjusted. When adjusting the volume with screen off, adjust the remote volume if applicable. When controlling volume, give priority to local media playback.
