In iReal Pro, go to More/Background Audio and make sure that it’s set to ON.
For an audio app to run background audio, it would have a setting for background audio OFF/ON. To run another audio app in the foreground at the same time, this app must allow the background audio through (many apps do not do this so you have to check.)
